I currently have an illegal version of XP Pro Corp installed on my computer, as of today windows update has stopped me from being able to update my version of windows, i've tried ways around it without any success.

My options are to:
- obtain updates 'elsewhere'
- Format and install a diff version or my legit xp home
- Convert my current version to home.

Is there a way to convert it to home so i can use my original serial??
