Windows 7: Uninstall Powershell 1.0

14 Aug 2009   #1

Windows 7 build 7260
Uninstall Powershell 1.0

Anyone here know how to uninstall Powershell 1.0?

I would like to install 2.0 CTP3 and I can't do that till v1.0 is uninstalled.

According to the Powershell Blog website what is installed on Win7 RTM is v2 CTP3.

My version of Win7 has powershell v1, not v2. There is no uninstall routine and nothing documented as far as I can tell.

I searched Windows PowerShell Blog and found many others looking for a way to uninstall powershell, but no answers.

There's nothing inPrograms/Features... it's not in Installed Updates... and there's no Feature that can be disabled. I've heard hacking the registry can be done in some cases, but apparently this is dangerous--I read one story where someone had to reinstall after trying this.

Still looking for a way to get powershell 1 off Win7...

Still looking for solution to installing PS v2 on Win7

I also have the same problem. Cannot install Powershell v2 on Win7x64, but cannot find how to "uninstall previous version".

Has anyone made any progress on this?

Why do you think you have a version less then 2? The directory it is in? Unimportant.
While in powershell type "get-host" to get version information.

Thanks, logicearth.

PS C:\Windows\System32\WindowsPowerShell\v1.0> get-host

Name             : ConsoleHost
Version          : 2.0
InstanceId       : cee3ea88-5df9-42a0-b0d2-b32b6fd0f7fb
UI               : System.Management.Automation.Internal.Host.InternalHostUserI
CurrentCulture   : en-US
CurrentUICulture : en-US
PrivateData      : Microsoft.PowerShell.ConsoleHost+ConsoleColorProxy
IsRunspacePushed : False
Runspace         : System.Management.Automation.Runspaces.LocalRunspace
Still, as Microsoft software, it's not too much to ask for it to install/uninstall from Control Panel\Programs and Features. Perhaps next year...

You have version 2 making your problem not a problem.

Well, the problem turned out to be confusion due to misleading install directory and no entry in Programs/Features.

I tried renaming the install directory. Didn't work. Powershell could not load a slew of libraries, even after I changed registry entry.

The easiest thing to do is change shortcut properties "Start in:" entry to:

instead of:

Well I will be darned. I guess I do have version 2.0 already.
Confusion was created when I tried to install Powershell V2 CTP3, without realizing that it was already in Windows 7, and Powershell does not show itself in either the "Installed Programs" or Windows Components.
Also, I did not see it in All Programs untill I found it under "Accessories".
Thanks everyone.
