PowerShell News

Windows PowerShell just got a version update, V2 (CTP).

Windows PowerShell : Installing Windows PowerShell V2 (CTP) - PowerShell Blog

For some reason I was under the understanding that once PowerShell was installed on a system, it couldn't be uninstalled.  That post above actually shows how to do it:

Uninstalling Previous Versions of PowerShell

PowerShell v1 RTM shipped as updates to the OS. Therefore, it will show up only in the updates section. To look for previous versions, do the following:

On Windows XP/Server 2003:

Go to Add/Remove Programs
Select Show Updates

Look for any of the following KB numbers which indicate earlier versions of PowerShell
o   KB926139 – Windows PowerShell v1.0 RTM – English Language Version
o   KB926140 – Windows PowerShell v1.0 RTM – Localized Installation Package
o   KB926141 – Windows PowerShell v1.0 RTM – MUI pack
o   KB925228 – Windows PowerShell v1.0 RC2

Versions of V1 prior to RC2 are MSI based installations and they will appear as Windows PowerShell in the programs list

·         Uninstall the previous version that’s installed

On Windows Vista:

Go to Programs and Features
Click on View Installed Updates
Look for any of the following KB numbers which indicate earlier versions of PowerShell

o   KB928439 – Windows PowerShell 1.0 RTM
o   KB923569 – Windows PowerShell 1.0 RC2

Version of V1 prior to RC2 are MSI based installations and they will appear as Windows PowerShell in the installed programs list

Uninstall the previous version that’s installed

On Windows Server 2008:

Launch Server Manager
Go to Features
Click on Uninstall Features. This brings up a list of installed features to choose from
Select Windows PowerShell and uninstall

That's good information to know!
