I have spent the better part of a day hunting the Internet looking forr a way to download Powershell 2.0 to my already Win7 environment. Windows 7 is supposed to come with PS 2.0 however - I have 1.0.

How do you upgrade Powershell when there is no download made specifically for Windows 7?

It's weird that your Windows 7 has the version 1.0 when by default it has to have version 2.0. Any idea how this happened? Anyway just to confirm try running the command $psversiontable. If this command gives a result, you have version 2.0. – Thomas Jun 27 '11 at 14:22

I suspect that you really have 2.0. The 2.0 version installs in a directory named 1.0 which often causes this confusion. In a PS session type:


And I suspect that you will see:

PowerShell 2.0 ships with Windows 7 in the box.

Version 2.0 is integrated with Windows 7 and Windows Server 2008 R2 and is released for Windows XP with Service Pack 3, Windows Server 2003 with Service Pack 2 and Windows Vista with Service Pack 1.
