How to get around Windows PowerShell when upgrading XP to Vista

Medium Priority
Last Modified: 2012-08-13
Hello - I have an XP Pro SP3 machine with tons of applications installed, that I need to upgrade to Vista, and then to Win 7 Pro.  There is 1 compatibility issue preventing the upgrade, which is it wants PowerShell 1.0 to be uninstalled first.  The problem I'm having with that is that Powershell is not listed ANYWHERE as a program, hotfix, or update in the Add/Remove list.  Also, XP is not allowing me to back off SP3, which I think might include the PowerShell.  I tried removing the Powershell registry key, but it still fails the compatibility check.  Any ideas out there on how to get around or remove Powershell 1.0 to upgrade to Vista?

Hmm - I looked, and there is no Kb926139 anywhere in the registry.  I wonder if it's called something else?

Check in the Windows directory and see if there is a folder for kb926139
