Switching between Windows 8 versions, maybe for a reason or just out of curiosity (like me) has just got easier. Windows 8 Upgrade and Downgrade tool called UpDown8 can make easy upgrade from Windows 8 Core to Enterprise or downgrade to Enterprise to Professional.

For Windows 7, there was a Windows 7 Downgrader which did some registry edits to make downgrades possible. UpDown8 also does same thing. You don’t to open Registry and play dirty, this tool can do it on behalf of you.

If you are not yet on Windows 8 RTM Final build 9200 and still using RP then you might be looking for Upgrade of Windows 8 Release Preview to RTM without losing Data or Format.

If I’ll upgrade Windows 8 Enterprise to Windows 8 Pro this will be available for 180 days too?

    Rohit Langde - September 3, 2012

    Which version are you currently using? I am amazed to know that you are being given 180 days of trial period.

    Windows 8 Enterprise Evaluation version has 90 days trial period. Read more-
    While none of the RTM builds have any kind of Trial/Grace period to run. Read more-

      Andrei - September 3, 2012

      I’m talking about the initially 90 days trial plus the next 90 days after rearm. 90+90=180. It’s correct?

        Rohit Langde - September 3, 2012

        That is ONLY available on Windows 8 Enterprise Evaluation.
        If you use THIS Upgrade/Downgrade tool to get Professional version, it will ask you Key while installation itself and there is no grace period for PRO.

Do I need to reinstall all applications / tools / etc if I switch from Enterprise to Pro?

    Rohit Langde - November 7, 2012

    Yes, User applications will have to be re-installed.

      Arjan - November 7, 2012

      Which makes this tool utterly useless… Because I can just insert the dvd/usb/whatever or mount the iso and reinstall Pro version..
