    Can I use my old Product Key for a newer version of Windows on a fresh installation?


    Recently my old PC died and I just build another one. On my old PC I used a retail Product Key of Windows 8.1 and I know that I can use it again on my new PC as long that I delete my old device on my account. But do I need to reinstall Windows 8.1, activate it and then upgrade it to Windows 10/11 or I can just install Windows 10/11 and activate it with my old Product Key?

    :)

    Windows Product Key

    A friend of mine has an all-in-one that came with Windows 8 pre-installed. He erased the original OS thinking he could install another version of Windows 8. One thing he encountered, that he didn't expect, the BIOS/UEFI has a password. So, basically he is locked out from installing another OS. His BIOS has the product key nestled inside. Is it possible to find out which version the product key belong to?

    New Version of Windows XP to Combat Lack of Product Keys

    The current version of Windows XP Service Pack 2.0b is currently running very low on product keys, due to piracy the surprising longevity of the product. And so, to combat the lack of product keys, Microsoft is creating a fresh batch by releasing Windows XP Service Pack 2.0c. There should be no major differences, other than the latest patches built in and the new abundance of keys.

    This version of XP will only be available to OEM system builders, and will only be in the market until Windows XP's official EoL date: January 31st 2009. Retail copies of Windows XP will stop shipping on the January 31st 2008.
