Path to Powershell.exe (v 2.0)

Question

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:\Windows\System32\WindowsPowerShell> dir


    Directory: C:\Windows\System32\WindowsPowerShell


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.

Answer 1

I believe it's in C:\Windows\System32\WindowsPowershell\v1.0\. 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:

• 64 bits version: C:\Windows\System32\WindowsPowerShell\v1.0\
• 32 bits version: C:\Windows\SysWOW64\WindowsPowerShell\v1.0\
