  • You Don’t Have to Be An Administrator to Run Remote PowerShell Commands

    I was just read blog entry which complained about having to have administrative access to execute PowerShell commands against a remote server.  This is not the case. We are “ secure by default ” which means that if you want to do something that exposes a security risk to your machines, you have to make a conscious decision to do so.  We are secure by default so that you can feel confident...

  • Windows PowerShell and the Windows Management Framework

    There’s been a lot of great excitement that’s accompanied the release of PowerShell V2 and Windows Remote Management (WinRM) – also known as the Windows Management Framework. We’ve also heard the occasional question on whether it’s possible to install them independently. When we’ve heard this concern, it is usually focused on security. To be clear, Windows Remote Management (WinRM) has been part of...

  • Windows Server 2008 R2 Rocks!

    One of the things I like to say is that, “Microsoft is incapable of sustained error”.  By that I mean that Microsoft is an intensely self-conscious culture, fearless about confronting shortcomings and  constantly looking for ways to do things better.  We beat ourselves up pretty brutally about the shortcomings of Vista and committed ourselves to doing better going forward.  This...

  • Why is Get-ChildItem so Slow?

    We get this question fairly frequently when it comes to slow network connections. The performance of directory listings (especially on a laggy network) are limited by the .NET APIs we call to retrieve the directory information. There are two limitations to the current set of APIs: Forced Retrieval of Attributes When we do a directory listing, we show the standard attributes of the file or directory...

  • Workaround for Add-Member on plain .Net objects

    Introduction While I was fixing bugs, I came across an interesting bug ( https://connect.microsoft.com/PowerShell/feedback/ViewFeedback.aspx?FeedbackID=382818 ) that seemed to have a very simple fix upon first glance.
