Windows 7 Home to Pro Upgrade Problem

If you have installed SP1 you'll need to uninstall it first to use Windows Anytime Upgrade.

The upgrade from Home Premium to Professional will look for Windows Home Premium, not Windows Home Premium SP1.

SP1 (KB976932) can be unistalled via Control Panel>Programs>Uninstall a Program.

Actually mine went pretty smooth with SP1 installed, but I think there's something else going on here if the OP is having this much trouble upgrading, it certainly couldn't hurt to try it without SP1.

I find it listed by further going into "Installed Updates" under
Service Pack for MS Windows (KB976932) if the update was not carried out manually.

After Upgrade? Anytime Upgrade says the computer will automatically restart.

Did you install all Windows updates?
