In the Windows 8 Release Preview, we continue to deliver the re-imagined experience of the web browser, incorporating your feedback to provide the best browsing across all Windows 8 devices, including more of the web you browse every day. Rob Mauceri, the group program manager for Internet Explorer, authored this post. --Steven We built a new browsing experience in lockstep with Windows 8 to give you all the advantages that Metro style apps offer. We built that experience by extending IE’s underlying...

Today, Windows 8 Release Preview is available for download in 14 languages. This is our final pre-release, and includes Windows 8, Internet Explorer 10, new Windows 8 apps for connecting to Hotmail, SkyDrive, and Messenger (and many more), and hundreds of new and updated apps in the Windows Store. Since our first preview release last September, millions of people now use the pre-release product on a daily basis and millions more have been taking it through its paces, totaling hundreds of millions...

While we're hard at work making sure you never have to turn off your PC and can run in a connected standby state, we know that there will still be reboots for updating key system components. We've previously talked about reengineering the Windows boot experience and how we modernized and touch-enabled the core boot loader and choices. We've also made boot go by very fast . In fact, it is now so fast that we had to look at the design to enable the kinds of diagnostic boots required by those who do...

This post goes into the details around the multi-monitor experience for Windows 8. From the very first public release and demonstrations of Windows 8 we have shown improvements over Windows 7 for multi-monitor scenarios and have shown how we support new Metro style apps within a multi-monitor environment. We have continued to develop and refine features for multiple monitors and have significantly enhanced the experience as we move to our next milestone, the Release Preview. This post provides a...

This blog often focuses on the bits and features and less on the “philosophy” or “context” of the product. Given the level of brand new innovations in Windows 8, however, we think it is worth putting Windows 8 in the context in which we approached the design. As with any significant change to a broadly used product , Windows 8 has generated quite a bit of discussion. With millions of people using the Consumer Preview for their daily work, we’ve seen just as many points...

As we developed the app model for Windows 8 and the new Metro style apps, a key architectural requirement has been to deliver apps to customers that can be used with confidence--confidence that apps will be well-behaved with respect to resources, that apps will not interfere with other apps, that apps use system resources with your permission, that apps can be installed and uninstalled with ease, and so on.  These attributes require a robust platform and strong set of tools for developers. ...

One of the intrinsic capabilities of Windows 8 is the ability to use multiple accounts on any PC. This makes it much easier for parents to use tools that can help protect their children from content on the Internet as they see fit. It is also a great way for each family member to maintain their own unique online identity while still sharing a single PC. Microsoft has been a leader in creating tools to help maintain a safe computing environment for all users as well as for parents in particular. With...

We’ve written about tons of improvements in the OS kernel, networking, and file system. While for most client PCs, the tried and true chkdsk utility is one we rarely use anymore except in very rare circumstances, we are using Window 8 as an opportunity to improve this utility. We wanted to focus on rethinking how the utility works to increase availability and reduce downtime due to chkdsk operations. In looking at the real world usage of chkdsk, we note that corruptions are exceedingly rare...

We thought we would follow up the previous post with an FAQ which is based on the comments and discussions, so Bernardo put this together so things are in one place. Some of these might be introductory for some but since the comments covered a lot of topics, it seemed reasonable to start at the beginning. --Steven What are the codecs needed to play DVD? A codec is software that is used to compress or decompress a digital media file, such as a song or video. MPEG-2 is widely used as the format...

In this post we wanted to update you on Media Center and Windows 8, specifically how we will make sure Windows 8 fully supports the capabilities of Media Center as it is in Windows 7. We took the feedback about maintaining the functionality very seriously, and we clearly understood what we’ve heard many of you saying around the value of Media Center for movies, Internet TV, broadcast TV, optical media, music, photos, and all the other scenarios it covers today. Many said in comments and email...

We have talked quite a bit about SkyDrive and using your Microsoft account for the sign-in and roaming capabilities of Windows 8. These are just two aspects of a broad service infrastructure that you can tap into when using Windows 8 (and Windows Phone, Xbox LIVE, and a host of other services and apps). We want to talk more about the capabilities and features of cloud services for Windows 8 and Windows Phone. To get started, Chris Jones, the VP of our Windows Live group responsible for the development...

In February, we told you about our goals for connecting your apps, files, PCs, and devices to the cloud with SkyDrive and Windows 8 . Since then, we have provided the App Preview of a Windows 8 app to access SkyDrive, and we’ve updated the SkyDrive web experience. Today, we are delivering new capabilities for SkyDrive across the Windows platform. Mike Torres, and Omar Shahine, group program managers for SkyDrive, co-wrote this post. --Steven     Over the last year we’ve been hard at...

With more and more people providing their own hardware for work, the "bring your own" PC is becoming more commonplace and IT Pros want to have the confidence that they can support their clients who follow this trend. The presence of BYO does not change the need for IT Pros to manage, secure, and remain accountable for the network assets of an organization, and we all know that written policies can only go so far. This post focuses on managing WOA PCs, which are designed with this "consumerization...

Modern operating systems take a different view of the resources on the system. Regardless of the form factor, it is important for the OS to more effectively manage resource utilization than in the past. Currently, it is far too easy for a single process to consume available resources (memory, CPU, disk I/O) even when this does not improve the overall performance for end-users. The very role of an OS is to balance resources and make sure you can complete all the things that you want to do on your...

Last September we blogged about experiencing Windows 8 touch on Windows 7 hardware , introducing the story of touchscreen hardware, how it is evolving, and what we expect Windows 8 will bring to the ecosystem of touch. We discussed how our engineering efforts (software and hardware) are driven by key user experiences, how these experiences play a big part in how we evaluate Windows 8 hardware, and how we communicate with hardware partners. Since that post, we’ve been working closely with our...

There’s a ton of innovation in the world of displays—from pixel density, to aspect ratio, to core technologies. Windows 8 is designed to grow and improve as the display ecosystem grows and improves. Our goal is to support the broadest range of display technologies so PC makers can build PCs or you can use external displays that provide the best experience for your needs. To do this, we architected the WinRT to provide the platform necessary to support this diversity. This is a complex...

In this post we want to talk about the new Internet Explorer 10 browsing experience.  We have considerably improved the underlying browsing engine with performance , standards, and features as we have previously blogged about.  IE10 designed for a Metro style experience is a new and improved way of browsing, where you can truly focus on the information you want to browse rather than the task of browsing – a fully immersive experience.  At the same time it provides all of the safety...

As we start to talk about some more of the details of the Consumer Preview release and some of the changes, or just features we haven't had a chance to blog about yet, we wanted to take a step back and re-introduce the team a bit--a reminder of the people behind the features we talk about. Building Windows 8 is a pretty significant undertaking and involves a team with diverse backgrounds and experiences. We're proud of the fact that the diversity on our own team reflects the diversity of the customers...

We’re very excited to get to the point in the project where we can provide a pre-release version of Windows 8 that is broadly usable by the tech community on a daily basis. We know folks who are anxious to run the Windows 8 Consumer Preview are probably interested in suggestions around what hardware to use. This post provides the technical details behind system recommendations. These are not system requirements , and are not final, but simply a view of what works best for running the Consumer Preview...

Today is a big day for the Windows team. At Mobile World Congress in Barcelona, Spain a few moments ago, we unveiled the Windows 8 Consumer Preview to our partners and press. Based on a broad range of feedback, we have made over 100,000 code changes and the Consumer Preview represents a refined product ready for broad and daily usage by those of you willing to test a pre-release OS. You can download the Consumer Preview starting now at http://preview.windows.com . If you tried the Windows 8 Developer...

Since its introduction in Windows 2000, Multilingual User Interface technology, or MUI, has allowed customers to install additional display languages on their Windows PCs and to switch between them. But for the majority of users, the language you got when you booted up your Windows PC for the first time was likely the one you were stuck with. For Windows 8, we have reimagined the display language experience, focusing on making additional display languages available to all Windows users , making them...

Many folks reading this blog are active users of SkyDrive and Mesh, both part of the broad set of Windows Live services (like Hotmail), and the Windows Live Essentials programs (Messenger, Photo Gallery, Movie Maker, Mail, and more). With their introduction and with Windows 7, we have talked about how these services really complete the Windows experience. As we developed Windows 8, we thought deeply about how these services can take an even more active role in completing the experience—offering a...

A big part of this blog is going behind the scenes to show you all the work that goes into the engineering of Windows 8. In this post we take a look at something we all care very deeply about--as engineers and as end-users--real world web performance. We do a huge amount of work to get beyond the basics of anecdotes and feel as we work to build high performance web browsing. This post is authored by Matt Kotsenas, Jatinder Mann, and Jason Weber on the IE team , though performance is something that...

Windows 8 is a product we design for an incredibly broad spectrum of people around the world. One of the areas where we have worked to deliver an even greater level of innovation is in ensuring that Windows 8, particularly the new Metro style experience, is accessible to everyone regardless of their physical abilities. In this post we will talk about the engineering work that goes into the features we refer to as “accessibility” – though as you will see, many of these features are broadly applicable...

One of the notable aspects of Microsoft Windows has been the flexibility the architecture has shown through shifts in technology and expansion of customer usage over time. What started out as an operating system for one person working solo with productivity software is now the foundation of a wide array of hardware and software technologies, a spectrum of connected Windows products, and an incredibly flexible approach to computing. With Windows 8 , we have reimagined Windows from the chipset to the...
