Vista - Can't Uninstall Powershell!!!

Ok so I've tried everything. I am running 2003 64 bit.

1) After checking show updates there is not a powershell or windows hotfix
listed in the add remove programs.

2) in my C:\Windows directory there is not a $NtUninstallKB926139

3) There is not a powershell directory in my system32 folder

4) there is not a powershell directory in my registry under
localmachine/software/microsoft

When i download the install it still tells me I need to uninstall previous
version before I can install this one!!!

WTF!!! this is so frustrating.

Thanks in advance,
Greg

Meaning you don't find it in the Windows updates section despite
having checked the show updates checkbox?
I can see it here, it's called "Windoes Powershell(TM) 1.0 and has
the powershell icon.

Lots of Greetings!

Try running this utility:

http://www.microsoft.com/technet/sys...ssmonitor.mspx

while attempting the install. It will show which files and registry entries
the installer might be finding that would indicate that PowerShell is still
installed.

Perhaps:

Live Search: msiinv.exe

It will look for Software\Microsoft\PowerShell\1 value Install.

In 64 bit there is also a PowerShell key in the 32 bit mirror,
Software\Wow6432Node\Microsoft\...

Hi Greg,

Can you check whether you have "Microsoft Command Shell" installed in the
registry key ? Powershell is known as "Microsoft Command Shell" till Beta 2.
"Microsoft Command Shell" runtime used to be part of Windows SDK earlier.
The official name was announced after Beta 2. Because of potential legal
issues we were not allowed to show "Microsoft Command Shell" in the error
message during installation.

Hi

I have the same problem on thesame system. Found the foloving solution:

1. Rename or remove directory: C:\WINDOWS\SysWOW64\windowspowershell

2. export and then delete the foloving reg key:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\PowerShell

3. export and then delete the foloving reg key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell

4. Install new version of Power Shell

P.S. Now it is also listed in Add/Remove programs under the HotFix KB926139

As with others, I can't get rid of the Powershell virus. I uninstalled it
before upgrading to Vista Home Premium. Now am trying to upgrade to Vista
Ultimate and I am getting the message that it must be removed again!. I have
attempted to remove it using the add/remove programs. It keeps reappearing.
I was able to rename, but not remove the Windowspowershell directory.
Regedit will not let me delete either of the PowerShell keys. I get a
message "Error While Removing Key".

There has to be a better way to get rid of this curse.

Powershell can be uninstalled via control panel -> Turn Windows featured on or off
Deselect Windows Powershell and reboot.
