    Assuming that is successful will I then be ok to go back and use MCC again to do a clean install?


    Thank you
    Yes, absolutely. 1. Great that you created a backup before moving to Windows 10! 2. Make sure the Windows 10 that you upgrade to is fully activated before you clean install over it. From an elevated command prompt ("Run as Administrator" command prompt) type slmgr /dlv . Look in the information returned for an expiration date. You should not find one. Then type slmgr /exp . That should return that your machine is permanently activated. If you get those two results, you are supposed to be good to go to do a clean install of the same version of Windows 10 and "skip" or "do this later" when it asks you to enter a product key.

    All seems ok and running slmgr /dlv under cmd as administrator does not show any obvious expiration date. Running slmgr /exp returns that "/exp" is "unrecognized option" but does display several pages of information all of which you have to press OK on to move to the next but means nothing to me.

    What I have noticed is that the last 5 digits of the product key which it displays are identical on both my updated machines. Are in fact all the upgrade and subsequently clean install product keys the same / generic or is something wrong?

    "System" under "Control Panel" on both machines shows product key as being activated.

    Oops. Meant slmgr /xpr

    All product keys for Windows 10 upgrades will be the same for same versions. Upgrade Windows 10 product keys are now only placeholders and can be ignored by users.

    That works! I can see the shiny smile now!

    On the first upgrade here that actually went on back at the end of July I ended up trying the in place upgrade to repair type install and that went well for a change seemingly "bug free". BUT! It simply wouldn't activate during that first week and by the weekend knew it was time again for the "clean install"! That activated within a day!

    Since then the second desktop and laptop seeing two initial upgrades and 5 clean installs two on the desktop and three one the 32bit on the laptop that had been running the 32bit 7 was then to see the second clean install become the 64bit followed by a need to nuke the OEM primary off the drive when you couldn't shrink it or grow it to fill in where the other small OEM and 3rd party ware parts had been. In each case however upon arriving at the desktop for the first time and checking all went well finding them all acitvated by the time the set up was finished!

    Surprisingly other then the repair install on the first system the second desktop not the laptop however saw a totally bug free upgrade the first time around! I had put a clean install on a second primary created to test the notation you could use the same media on various machines without seeing an upgrade on each one separately? FALSE! Mandatory! The first clean install only confirmed what I already knew!
