Upgrade to Windows 2008 is Blocked by Windows Powershell

19 June 2012

When trying to upgrade Windows 2003 to Windows 2008, the upgrade may fail because Windows Powershell is installed. You may then be unable to find Windows Powershell in Add/Remove Programs, even when you look at installed updates, and even when you look for any of the various KB numbers. A workaround is to rename the C:WindowsSystem32WindowsPowerShell folder (and C:WindowsSysWow64WindowsPowerShell in x64) and retry the upgrade. You’d think it would look into the registry or something, but it doesn’t!
