Many of you know I have been a fan of PowerShellPlus for quite a while, but I was turned on to a new editor the other day that’s pretty slick – PowerGUI . Winner of this years Windows IT Pro Magazine’s Best of Tech Ed IT Pro Breakthrough Product Award this editor/GUI is not to shabby… The editor and...

I  got a great question based on yesterday’s post (by the way my e-mail was blocking a lot of external messages that’s fixed now so I apologize to anyone I missed a mail from).  The person was asking how they could figure out what physical disk a virtual machine is using when configured for...

Hyper-V WMI Documentation First off I am happy to say the Hyper-V WMI documentation is finally post beta quality!  I want to personally thank a few members of the test team for writing much of the sample code and working very hard to get it posted.  There are now samples in C# and VBScript...

Hyper-V has a WMI API that will allow you to create a thumbnail image of any running or paused virtual machine.  You can create any sized thumbnail you want (640x480, 800x600, 1024x768 etc…).  Creating the image is pretty easy, you just call GetVirtualSystemThumbnailImage passing a reference...

Since I did my last post on snapshots I have gotten several comments and few e-mails asking how to map ReturnValues to actual human readable strings.

Hyper-V virtual machines have configuration options that control what happens when the parent/host server shuts down, start’s up, or if a virtual machine’s worker process terminates unexpectedly.  The first two conditions (parent/host shutdown, startup) are pretty self explanatory but what would...

I have officially given up on the “Hyper-V WMI Using PowerShell Scripts” serious, not because of lack of interest but because or extreme interest implying that I would need to do Part 5, 6, 7, 99… Counting past 5 is hard so from now on I will just title the posts for what they are doing.
