Path to Powershell.exe (v 2.0)
Where is the Powershell (version 2.0) located? What is the path to Powershell.exe? I have Windows Server 2008 and Powershell installed. When I look at this folder:
PS C:WindowsSystem32WindowsPowerShell> dir
Directory: C:WindowsSystem32WindowsPowerShell
Mode LastWriteTime Length Name
---- ------------- ------ ----
d---- 20.4.2010 17:09 v1.0
I have only Powershell v1.0. But when I type
PS C:> $Host.version
Major Minor Build Revision
----- ----- ----- --------
2 0 -1 -1
PS C:>
It shows that I have v2.0 installed.
I believe it's in C:WindowsSystem32WindowsPowershellv1.0 . In order to confuse the innocent, MS kept it in a directory labeled "v1.0". Running this on windows 7 and checking the version number via $Host.Version (Determine installed PowerShell version) shows it's 2.0.
Another option is type $PSVersionTable at the command prompt. If you are running v2.0, the output will be:
Name Value
---- -----
CLRVersion 2.0.50727.4927
BuildVersion 6.1.7600.16385
PSVersion 2.0
WSManStackVersion 2.0
PSCompatibleVersions {1.0, 2.0}
SerializationVersion 1.1.0.1
PSRemotingProtocolVersion 2.1
If you're running version 1.0, the variable doesn't exist and there will be no output.
Localization PowerShell version 1.0, 2.0, 3.0, 4.0:

Here is one way...
(Get-Process powershell | select -First 1).Path
Here is possibly a better way, as it returns the first hit on the path, just like if you had ran Powershell from a command prompt...
(Get-Command powershell.exe).Definition
