Legally downgrade Windows Vista Home OEM license?
I have a HP Probook 4410s laptop which couldn't boot and I did a clean install of the OEM Vista that came with the laptop. After everything was up and running, I was told by the user that it was originally XP.
Indeed, i later found the OEM XP as well. To complicate things, the sticker on the bottom of the laptop has faded and I cannot make out whether the key is for Vista or XP. I then tried to change the product key to the sticker key, but the system says it is invalid. Then again, I read that the sticker does nothing from some other forums.
I don't want to redo everything or go back to XP (yes yes, Vista worse than XP, doesn't matter) So is it legal given my situation? I don't understand why they would give 2 version of Windows for nothing.
