PowerShell & System Center

Check if PowerShell installed and version

To check if PowerShell is installed use:

HKLM\Software\Microsoft\PowerShell\1 Install ( = 1 )

To check if RC2 or RTM is installed use:

HKLM\Software\Microsoft\PowerShell\1 PID (=89393-100-0001260-00301) -- For RC2
HKLM\Software\Microsoft\PowerShell\1 PID (=89393-100-0001260-04309) -- For RTM

Also you could do the following

PS C:\Myworkplace\PS> get-host


Name             : ConsoleHost
Version          : 1.0.0.0
InstanceId       : 2a52c07a-b708-430b-952a-af9f73431b46
UI               : System.Management.Automation.Internal.Host.InternalHostUserInterface
CurrentCulture   : en-US
CurrentUICulture : en-US
PrivateData      : Microsoft.PowerShell.ConsoleHost+ConsoleColorProxy

 

PS C:\Myworkplace\PS> $host.version

Major  Minor  Build  Revision
-----  -----  -----  --------
1      0      0      0

But the above will only give you the host version not the file version and for most people that’s good enough.

In case you are curious, you could do the following

PS C:\Myworkplace\PS> (gcm "$PSHome\PowerShell.exe").FileVersionInfo.ProductVersion
6.0.5429.0
