Vista - Can somebody help me uninstall powershell RC2?

It's not appearing in my "add/remove programs" list.

I've done this:
Get-Process -Name powershell | Format-List -Property ProcessName,FileVersion
,StartTime,Id

ProcessName : powershell
FileVersion : 6.0.5429.0 (winmain(wmbla).060830-0116)
StartTime : 11/21/2006 7:30:52 PM
Id : 5392


The shortcut brings it up just fine:
%SystemRoot%\system32\WindowsPowerShell\v1.0\powershell.exe

Does any of this information either confirm which version (RC2 or 1.0, which
I'm 99.9% certain I hadn't installed yet) I have?

And can somebody tell me how to uninstall it even though it doesn't appear
in my "add/remove programs" list?

Thanks,
Gil Novak

Be sure to have updates displayed in the add/remove programs dialog. There
must be a check box somewhere to do this.
Based on the Fileversion I think this is RC2 which is basically the same as
RTW 1.0 (which just comes with a different installer).

I do have "Show updates" checked and it really isn't on my list. Is there no
command line equivalent way to uninstall? Or even some detailed steps on
what files to delete, and what registry entries to remove?

Thanks,
Gil

Check the result of this oneliner:

ls HKLM:/software/Microsoft/Windows/CurrentVersion/Uninstall |
%{gp $_.pspath} |
?{$_.DisplayName -match 'PowerShell'} |
select DisplayName, UninstallString

If it does not show up, then try my uninstall string:

DisplayName : Windows PowerShell(TM) 1.0
UninstallString : "C:\WINDOWS\$NtUninstallKB925228$\spuninst\spuninst.exe"

This happened to me on one of my PCs. Here is what I did:

Delete the C:\Windows\System32\Windows PowerShell directory
Delete the following registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell

Now try to install it. BTW this is likely to leave older PoSH assemblies in
the GAC but that shouldn't cause any problems other than taking up some
extra disk space.

You might want to try dreeschkind's suggestion first. In my case the
$NtUninstallKB925228$ dir in Windows no longer existed so I couldn't
uninstall it that way.

Very nice! Thank you very much! That worked :-)

Happy Thanksgiving!
