Engineering Windows 7

Welcome to our blog dedicated to the engineering of Microsoft Windows 7

A few more changes from Beta to RC…

A few more changes from Beta to RC…

Hey folks, just wanted to provide another update (building on the recent post on some changes since Beta) on some of the changes you will see in the Release Candidate.  Again, there are many and this is not an exhaustive list.  Of course we continue to gather telemetry from the large number of people running the Beta full time.  Just a reminder, the Beta is the only official build from Microsoft.  Chaitanya compiled this list from a broad set of feature teams focused on visible changes based on feedback that go beyond “bug fixes”, though we included some of the more widely reported bugs on this list as well. –Steven

Desktop Experience

1. Improved taskbar thumbnail overflow

Our customers are enjoying how windows are grouped and revealed on the enhanced taskbar. Some enthusiasts who have a significant number of open windows for a program encounter our scaling mechanism; the thumbnail view turns into a list view. Although this UI is virtually identical to experience in XP and Vista, customers still want to enjoy new functionality of the thumbnail view. Bentronic wrote, “It's nice that there's a little close button on the thumbnail previews--why not have a similar button for when it's showing as a list?  Being able to run down the list clicking the close button instead of right-clicking would be great.” For RC we’ve made the list view architecturally the same as the thumbnail view, just sans thumbnails. Customers will now enjoy close buttons and the menus open on hover (in Beta one had to click to open them).

2. Control Panel Jump List

Right-clicking on the Control Panel icon on the taskbar in Beta revealed a noticeably sparse Jump List. A few people such as Britney told us “Should most recently used items be displayed in the Jump List of the CPL when pinned to the taskbar? Something should be shown and nothing is there right now”. In RC the Control Panel Jump List offers quick access to recently used items.

2. PowerShell Jump List

By default PowerShell in Beta launched a streamlined console. Customers could load optional modules via distinct shortcuts in the Start Menu. We heard from you that this was a confusing experience. Additionally, PowerShell did not surface a way to launch related tasks such as the Integrated Scripting Environment (ISE) from within their console experience. PowerShell now has a robust Jump List that affords a method to load modules, launch the ISE and open documentation.

3. Remote Desktop Jump List

Rajeev made us smile with his comment, “Being able to add my Remote Desktop shortcut to the taskbar—good. Saving settings and showing them in the Recent items section—awesome. Being able to pin the connections in the Jump List, so they always appear—priceless!” Well, Rajeev and others who shared this request, you will be enjoy this functionality in RC.

4. Applying taskbar settings

Have you ever customized the taskbar, only to find your changes were not saved across sessions? Has the taskbar ever inexplicably moved on you after you log in? For a variety of reasons, previous versions of Windows saved taskbar settings only after Explorer exited at the end of a session. However, if the OS is not shutdown properly these settings did not persist. Based on the bugs we saw from Beta, we decided to change our architecture and write these settings within 30 seconds (providing enough time to batch a group of changes) during the session. This means settings will now be more reliable.


5. Multi-touch zoom

One of the pieces of feedback we heard from the Beta was that customers enjoy the new multi-touch zoom feature, but wish it was supported in Windows Explorer.  In response to this feedback we have added support for the zoom gesture in Windows Explorer.  Using the zoom gesture you can switch between view modes in Explorer such as zooming from Small Icons to Extra Large icons.

Windows Explorer and Libraries

6. Invert Selection

In an effort to make improvements to performance, network bandwidth and memory footprint for various scenarios (e.g. libraries, search and search federation), we rearchitected the implementation of the view code in Windows Explorer. As part of this we did not to port “Invert Selection” since this rarely used feature is pretty complex to implement in the context of virtualized lists.  Despite the small percentage of usage we’ve recorded, those who missed it have been pretty vocal :-)  On one of the blog posts, GGreig summarized what we heard from several of you—“Invert Selection; that's a useful - sometimes absolutely invaluable - little piece of functionality, and I definitely don't want to see it go…Please reinstate Invert Selection.” Given the feedback from enthusiasts, we added back the functionality for RC.

7. Going up?

We’ve heard feedback, especially from those on this blog,  that in Windows 7 moving up in the folder hierarchy often requires multiple clicks since longer folder names in the address bar often bump the parent folder into the overflow dropdown.

For RC, we’ve improved the overflow algorithm so that the parent folder’s button will appear in the address bar at all times and therefore going ‘up’ will always be a single click away in a predictable location.  When there isn’t enough room to display the parent folder’s full name, it will appear truncated instead of going into the overflow.  If space is especially tight, then the current folder’s name may appear truncated too, but in all cases the parent folder’s button will remain as a click target in the address bar. 

In addition to making the address bar an even better tool for navigating ‘up’ in Explorer, this change also makes it easier to tell where your are as you navigate around since you can now see at least part of the parent folder’s name.  It also avoids introducing any more redundant buttons to the Explorer frame and hence taking away any more screen space from being able to see your address. Also, it goes without saying that if you navigate into a folder, you can still use the back button to go back up.  And the keyboard shortcut is also available.

In Beta, a parent folder would collapse into an overflow dropdown

In RC, parent folders always remain within single click access

8. Finding music by artist

We covered several of the improvements to arrangement views in the last post, but one we did not mention is that the “Artist” view in the Music Library now accounts for album artists and compilation albums.  ShadowChaser summarized some feedback we heard from a number of customers in a comment: “The only concern I still have is with the ‘Artist’ view… it groups by ‘Contributing Artist’, not ‘Album Artist.’”  Grouping only by contributing artist results in too many artists showing up and tracks from the same album getting split up in cases where customers didn’t expect.  In RC, the “Artist” view in the Music Library groups together multiple tracks from an album by the common “Album Artist” property when it is available, groups tracks from compilation albums together into a “Various Artists” group and finally resorts to grouping by “Contributing Artist”.  This reduces clutter when browsing music collection by artist, in addition to improving consistency with artist views in other applications and devices.

9. New folder is always available

We’ve gotten a lot of positive feedback during Beta about adding a top level “New folder” button in Explorer, freeing customers from digging into submenus.  A common complaint we received, however, was that the button only appeared when nothing is selected.  For RC, we’ve changed this so the “New folder” button will always appear, regardless of selection.

10. Right-click in Windows Explorer

For RC we’ve changed the behavior when right-clicking items in the view to address concerns customers were reporting with the Beta.  We heard feedback that it was too hard to find space and get to the view’s background context menu for items such as New and Paste.  Previously if one right-clicked over any portion of an item she would get the item’s context menu.  We now show the view’s context menu when one clicks on any large white space, including the space between a files name and its properties.

11. Content view for search results

For RC we’ve adjusted the behavior when right-clicking items in the view to address concerns customers were reporting with the Beta.  We heard feedback that it was too hard to find space

Content view is the new view mode we’ve added to Windows Explorer for Windows 7.  It’s especially useful for search results where it surfaces the most relevant properties for each kind of file (e.g. documents, email, pictures and music) as well as a contextual “snippets” of the file content where the search term match occurred.   There are a few changes here in the RC build.  One thing we heard feedback on is that customers want to know exactly which properties were being shown for each item, so all properties now appear with labels.  The text layout and colors have been updated in response to feedback to make each item even easier to parse and to avoid confusion with the colors used for encrypted or compressed files.  We heard loud and clear that many found snippets very useful and wanted to see more of them, so in the RC we’ve allowed longer snippets and we’re using them in more places.  In response to feedback we heard from customers when resizing their Explorer window or toggling the preview pane, we’ve made the transitions smoother as additional columns of information about each item are revealed when you make the view larger.

12. Intelligent re-indexing after application installation

In RC the Windows Search service now keeps the index up-to-date whenever support for new file types are introduced to the system.  We know that in the past customers have sometimes had difficulties searching for files on their computer after new file handlers are installed. (File handlers govern how content and metadata is made searchable and are typically installed with applications such as Microsoft Office or updates such as the Microsoft Filter Pack).

In Win7 Beta (and previous versions of Windows), customers were required to rebuild their index whenever a new file handler was installed to ensure that any existing files were indexed with the newest functionality.  Few customers knew to do this and it was an unnecessarily time consuming operation.  Windows Search is more efficient in RC by automatically re-indexing the specific files affected by new file handlers. Rest assured that when one installs support for a certain kind of file, she can search for those files without doing any additional work.


13. Trimming sound schemes to help performance

We know our customers care about performance. We discovered that by just trimming the shutdown and logoff WAV files, we could save up to 400 ms. Every little bit counts.

Device Stage

14. Baseline Device Stage experience

Device Stage continues to enjoy positive reviews. For example, we saw this post on on a blog: “I have to be honest this works very well, it worked with my MP3 player in showing how much charge it had and other details as well is able to display the manual and offer me everything I needed to do with it effortlessly, including having the correct icon and image of the product.” However, we occasionally hear “too bad , my N70 aint supported either :-( …hopefully they are gonna support a ton more device by the time windows 7 get released”.

We took feedback like this to the devices makers and they too would like more integration given the interest from our customers. Several manufacturers are implementing custom experiences, but a large number have also opted to support their older devices in what we call the “baseline” Device Stage experience.

This UX works exactly like full Device Stage; the device image appears on the taskbar whenever it is connected and tasks are exposed in the Jump List. On first connect, the shell Window containing all of the built-in tasks appears automatically and is always just one click away from the desktop icon or device image in the Devices and Printers folder. When the device maker implements a custom Device Stage experience for a device, it gets posted on the Web and the baseline experience gets upgraded when the device is later reconnected. The core functionality is the same, but all of the branding, imaging and vendor-specific tasks are now available automatically in the same convenient UI.

15. Devices and Printers enhancement

PC and laptop makers such as Lenovo, were very interested in doing more than just showing the machine’s icon in Devices and Printers. They told us they wanted to leverage Device Stage to help them better customize the experience for our mutual customers. In RC double-clicking on the PC icon now offers a Device Stage UX. Like the other Device Stage devices, Device Stage for PC will be enabled when the PC maker has chosen to participate with their system.

Devices and Printers

16. Unified experience for removing devices

One of the tasks customers perform in Devices & Printers is removing devices that are no longer in use. We received feedback that the remove action varied across different device classes. For example, removing a printer only removed the print queue and for Bluetooth devices it only removed the pairing of the device to the PC. We have changed this action to always completely uninstall the device across all device classes – which is the action that most customers expect.

17. Hardware properties

We know enthusiasts use the Device Manager’s property page to check the status of a device. We heard feedback that this wasn’t convenient and so we now also surface the property page directly from the Devices and Printers experience. Simply right-click on the device and one has one less reason to visit Device Manager.

18. Improved eject experience

The Safely Remove hardware functionality enables customers to make sure that their device is ready for removal. During the Windows 7 Beta, customers still had the Safely Remove Hardware functionality available on the taskbar as well as an Eject option on the context menus of applicable devices in Devices and Printers. Based on feedback, we have integrated these two separate pieces of functionality in RC and have changed its name from “Safely Remove” to “Eject”. The tool Notification Area icon still appears, but its context menu now has the option to open Devices and Printers.  Also, we have simplified the options by eliminating the drop-down submenu and made the semantics for eject functionality more consistent across the different kinds of media. For example, ejecting an optical drive now ejects the media instead of the drive and ejecting a USB flash drive ejects the entire device instead of an individual volume.

19. USB device reliability on resume

We got feedback from a number of customers that their USB devices (e.g. keyboards, mice and drives) stopped working after a suspend/resume cycle. We worked with a number of customers to get traces and isolated the causes to address them post-beta builds. The work around in Beta was to unplug and replug the device to get it functional again—easy for external devices but not possible for internal devices. This workaround will not be needed on RC builds.

20. FireWire camera support

Some customers informed us they were unable to connected their 1394 HDV camera and stream its contents to their Beta machine. With the help of customers, we were able to identify a fault with our core 1394 stack and we’ve validated the scenario works in RC.  This is another good example of the combination of telemetry and more “manual” follow up on the part of our test team.

Device Installation

21. Add Legacy Hardware functionality restored

The Add Legacy Hardware action was provided in Device Manager on past Windows releases to install non-Plug and Play devices. We removed this functionality for Windows 7 with the belief that this was rarely used. Aaron blogged, “You might have noticed that the old 'Add Legacy Hardware' option seems to be missing. I tend to use this quite a bit whenever I need to add in a Loopback adapter or some piece of hardware that is not quite installing correctly.” As a result, this functionality has been restored to Device Manager for RC to help add non-Plug and Play devices.

22. Increased responsiveness of Add Printer Wizard

There are some situations with legacy network printers in which Plug and Play cannot automatically identify the appropriate driver even when it’s available on Windows Update. For these situations, the Add Printer wizard allows customers to download a list of all the printer drivers available on Windows Update so they can manually select the driver for the specific printer being installed. The process of retrieving the list can take a few minutes and we received beta feedback that many people felt their machine was hung since there was nothing in the UI to let them know that it could take a few minutes.  We have made some UI changes to indicate that process of retrieval can take some time. Additionally, we have also improved the overall performance of retrieving the list from Windows Update.


23. Partition size reduction

In Windows Vista, configuring features such as Windows Recovery Environment and Bit Locker required significant customer interaction.  Also, a significant amount of drive space was reserved. The Windows 7 System partition enables features to be configured to work “out of the box” so very little customer interaction is needed to configure and utilize them.  Based on feedback and telemetry data received through the beta, it became clear that we could cut the drive size in half (from 200M to 100M). 

24. Reserved System Partition naming

The system partition is created automatically by Setup when installing on a machine with no existing partitions.  During the Beta the existence of this partition on default installs confused many people and feedback indicated that a label telling them that this is space reserved for the system would be helpful when browsing disk configurations, and further help prevent it’s accidental deletion by enthusiasts. We will now label is “System Reserved”.

25. Dual Boot partition drive letter assignment

For a dual boot configuration for the Beta, the other Windows OS wouldn’t get a drive letter and therefore wouldn’t show up in explorer.  We heard overwhelmingly from Beta customers that the lack of a drive letter was confusing and even caused some to believe that their secondary OS was lost. Assigning the drive letter makes it visible in explorer and aids in navigation across OS installations.

26. Pagefile reduction

Through extensive use of Beta telemetry data, we have determined we can slim down the Windows disk footprint further by reducing the default page file size to be 100% of the available main memory.  It used to be “Memory + 300MB” so on a 1GB RAM system there was an extra third allocated that is no longer required.  The pagefile on some occasions will increase in size if required, but we just pre-allocate less.


27. Improved driver support

Based on telemetry data received from the beta, we identified networking drivers that were not available inbox.  We worked with ecosystem partners to achieve increased inbox driver coverage across wireless and wired with significant coverage for some of the new ATOM-based laptops.

We hope you enjoyed yet another sneak peek into what’s coming in RC.

  • Please add 3 and 1 and type the answer here:
  • Post
  • My Belkin N1 802.11n Wi-Fi NIC doesn't have built-in drivers, so it's impossible for me to go online to download other drivers. Also, the Microsoft USB optical mouse can't wake my laptop from sleep (No Power Management tab) but my internal trackpad which also shows up as attached by USB can!).

  • First a suggestion:

    Now, when you do a CTRL click on a icon in the taskbar, you cycle trough the open windows of a given program. You can also do a WIN + # cycle for the first 9 icons in the taskbar.

    Could you please add a relative way of cycling trough open windows of the current program?

    Based on CTRL being used with the mouse, I suggest CTRL + ALT + TAB for changing only between windows of the current program.

    There is also a problem with closing windows with ALT+F4, because if you previously clicked on a desktop gadget it gets focused after all windows are closed and the next press closes the gadget without a warning and you lose all of the gadgets settings. The problem also lies within the fact, that you don't even know the gadget has focus.

  • whay not have a live thumbnails preview for windows showing in list?? just like vista and also to keep the close button which was added to RC.

  • A couple of comments from what I've read.

    I believe that Microsoft should consider taking the Zune Player and adding what the Zune Player is lacking to become a full-fledged media player. Instead of having WMP in Windows, the new Zune Player should become apart of the Windows Live Essentials Suite. The Zune player has the potential to completely replace Windows Media Player. Instead of trying to overhaul WMP again, you can start from scratch with Zune.

    I think that virtualization will eventually be apart of Windows 7. However, virtualizing 16 Bit applications is pointless. There are so many security issues with 16 bit and many poorly 32 bit apps/software. It is really time to either re-write them as 32 bit with security in mind or 64 bit ones with security. Holding on to these legacy software and 16 bit is more of a threat to Windows security than moving foward in my opinion. I believe it is time to re-develop 32 and 64 bit to better tackle security issues.

    I do agree that Windows needs to be distinguish between kilobytes, megabytes, gigabytes, and terabytes correctly.

    Any issues with IE 8 might be that many websites have not properly coded and tested their website with IE 8. Unfortunately, many do not participate in Beta testing, RC testing, and wait until after the browser is out to make changes. Those who have are rendering properly. A lot of websites have not been updated. Please keep that in mind.

    I'm using a much more updated version of IE 8 and Windows 7 Build 7057. It works a lot better than the beta build 7000. IE is 3 times better than the beta and RC builds. I have some friend who has access to the updated builds. You guys are really going to love the RC.

  • I have thoroughly enjoyed the simplicity and lean functionality of the Windows 98 start menu on XP and Vista for many years.

    However, withe '7' Beta 1, the Classic Start Menu is not an option when right clicking on the taskbar. This is one of the few reasons why I am hesitant to upgrade when this product comes out. I want to be able to use the windows 98 style start menu on Windows 7.

    One more thing, under Power Options in Control Panel, with '7', it is no longer possible when pressing the power button on one's laptop or desktop, to have it bring up a menu of what the user wants to do (Sleep/Hibernate/Restart/Shutdown/LogOff). The "Ask me what to do" option is not available for the list of possible responses Windows 7 gives when one presses the power button of the computer, from the list under "Power Option" in Control panel when configuring the button reaction the OS gives.

    I would like both of these features re-implemented and then I will as happy as a duck!


  • As writen, it could be extremly useful to have a new folder shortcut!!!

    Is it possible to desactivate in an common explorer the Ctrl+Z shurtcut (undo).

    I use to work in multi display environment with several applications opened, and sometimes I do Ctrl+Z into the wrong windows, I know it's a mistake, but this command into explorer is useless for me.

    Great work on RC!

  • Couple points.

    Show desktop...why in the world is it glued to the left. Please put it back where it belongs.

    Search. Please fire whoever created the new search. Then, zip over to Google, learn what search otta be...return and redo, properly. As it stands, you've taken a poor system, and made it horrendously worse.

  • I must applaud, as 7048 has been an overall big improvement.  The annoying Start Menu "File is in use" bug that plagued me in 7000 is gone (every time I tried to MOVE a folder from my User's Start Menu to the ProgramData one, I would get denied due to the files being "in use").  A few other little quirks in gadget rendering have been fixed (I can now finally use the Weather Channel gadget again).  And I've noticed that I've had less Sleep->Crash accidents than before (down to one from one a day).

    The downsides?  Well, a nice feature of Explorer got yanked: persistent browser windows.  Like Invert Selection, it's just gone.  I hope it comes back, but since nobody else is clamoring for it, I assume the community cannot change the Windows team's mind on this.

    Also, the taskbar STILL looks atrocious when put on the side of the screen.  The icon tiles are over-wide in large icon mode.  And in small icon mode?  The bar doesn't shrink at all, the icons just get smaller with a TON of wasted space on their sides.  I still think that 24 pixel icons would be more aesthetically pleasing for the small icon mode, but do understand that most programs don't contain the size since Windows never really used it before.

  • [Intense Suggestion]

    all View Mode can adjust icon size (for Touchscreen)

    if you need view 'Details' mode, when you use Touchscreen, these icons very small in 'Details' mode...

    Mac v10.6 will support all View Mode can adjust icon size.

    Linux's desktop system already supported.

    Why not support for Windows ?

    View Mode: Icon, List, Details, Tiles, Content

    icon size: Extra Large, Large, Medium, Small


  • Quote from

    "Date modified should always and forever be a default detail, no matter the folder type. If you refuse to make that available, say, in Photos folders, at least make it available in the primary context menu when you go to add new details. Making me dig through some of the crap details available INTO the "More..." dialog is absolutely nuts. Date Modified is wildly useful; Date Taken (which takes its place in Photos folders) is unreliable at best and does NOT provide the same utility."

    I agree strongly with chriscardinal.

    Please set "date modified" back in every view.

    The omission of this in inexplicable regarding the fact that you do do many usability tests.

  • Intense Suggestion


    keep Details Columns style consistency...

    Details Columns has two styles in Windows 7.

    Please keep style consistency for Details Columns.


  • Guys, what about a problem with DirectSound3D hardware mixing in Vista? Does this annoying developer's mistake is fixed?

    I've Creative X-Fi Platinum, so why i have use dozens of wrappers (trash like ALchemy) to get hardware mixing (btw, ALchemy works properly in very rare cases) under Vista!?!? (XP hasn't such problem)

    Please, fix problem. Software-mixing only is the past century and must not be a part of upcoming OS.

  • Hi,

    I would like you to make this path window re sizable and please, implement the same functionalities for file copy as the one made by SuperCopier.

    Your file copy options have always been insufficient.

    Thanks in advance

  • Windows 7 is telling me "Your battery is bad and may cause your computer to shut down quickly." I absolutely love that Windows has the ability to know such things. This is a wonderful advancement and I realy think more things like that should be put into development. For example, Windows knows my battery is bad, but what if it could do something about it? Windows could have a utility to help put the battery through a full discharge and re-charge cycle. I know some high-end IBM laptops have had this feature. I don't think a lot of consumers know about the benefits of doing this. Windows could realy help stretch the lifespan of batteries just by adding a simple feature like this.

  • I too had problems with my mouse and keyboard in windows 7. I hope the bug you fixed is the same I encountered. I am using a ThinkPad R61 and the mouse, when connected to the dock, intermittently stops working for a second or two, but only when other devices are also connected to the usb ports of the dock. I think it was my printer which when connected messed up the mouse. Also, yesterday the keyboard stopped working after leaving windows 7 idle for an hour (it didn't go to sleep). A sleep/resume cycle made it work again.
