Before upgrading from Windows XP / Win2k3 to Windows Vista/ Windows Server 2008, we need to uninstall Windows Powershell first

Today I find one interesting issue. If you have Windows Powershell install on Windows XP / Windows Server 2003 and if you want to upgrade to Windows Vista / Windows Server 2008, the upgrade wizard will tell you that you need to uninstall Windows Powershell first. Where can you uninstall Windows Powershell?

















There are 2 ways to do so. One is to go to Add or Remove Programs, select “show updates”, and you can uninstall it.















The other one is to go to C:\WINDOWS\$NtUninstallKB926139$\spuninst, double click spuninst.exe, and then you can uninstall it. You can also use the command line to uninstall Windows Powershell as follows:
C:\WINDOWS\$NtUninstallKB926139$\spuninst\ spuninst.exe /q

After the upgrade, Windows Powershell is not installed on windows Vista / Windows Server 2008. If you still need it, you need to install it again.

For Windows Vista, you need to download Windows Powershell Vista version in Microsoft website.

For Windows Server 2008, Windows Powershell is part of the windows components. You can see use the following command line to install it.

ServerManagerCmd.exe /install PowerShell
