If you guys wanted to install PowerShell v2.0 CTP, the first thing you need to do is uninstall v1.0. Apparently, though, you won’t find any of those usual uninstall process like using the Add/Remove Programs console or the Uninstall Windows PowerShell from your Program Files. Have no fear. You can always use your registry. Simply look for the UninstallCommand key from HKLMSoftwareMicrosoftUpdatesWindows PowerShell 1.0 The path would really much depend on your operating system’s setup like what your service pack you are currently running. In my case, I am running Windows XP Service Pack 3 so the so the registry key for me would be HKLMSoftwareMicrosoftUpdatesWindows PowerShell 1.0SP3KB926139-v2 Run the Value Data from the UninstallCommand key to uninstall Windows PowerShell v1.0. Once you’re done, you can now install v2.0. You’ll be surprised that it now creates an entry in the Add/Remove Programs console.
