    Can I expect problems loading 8.1 with an 8 Product Code?


    I am sorry if this has been asked and answered before. I did a search and read the tales of woe on the subject. Mostly they were a bit old, datewise. Anyway, here goes.

    I have a W7 laptop and desktop. I bought 2 X Windows 8 Pro packages. I updated my laptop to Windows 8 Pro 64bit, all perfect, no problems. Never updated the desktop.

    Many months later, yesterday in fact, I ordered a new desktop. The retailer is loading Windows 8.1 Pro for me on the new desktop and I gave him the Product Key from the second package.

    Will he have any problems loading 8.1 Pro on my new system with my 8 Pro Product Key?

    Is there a proven method to load 8.1 with an 8 key? If so could someone please point me at it?

    I am asking in preparation, in case the retailer has problems so I can point him in the right direction.

    I am hoping, with the time passed, that my question has been answered by Microsoft

    Thanks in anticipation

    Not so much MS, however the installer should know by now and have the generic product key to install Win 8.1 pro and activate using your win 8 pro product Key hopefully they will clean install the 8.1 pro rather than upgrade a win 8 pro!!!

    My installer seemed reluctant to install 8.1 at all and would probably use the "too hard" excuse

    I did ask him to load RAID as part of the exercise as I use RAID 1 mirrors (another thread)

    I wouldn't be surprised if he avoids the whole exercise and just loads 8

    Any other ideas/suggestions?

    Hello Louwin, and welcome to Eight Forums.

    In addition, see if this may help.

    Activate retail Windows 8.1 with Windows 8 Product key.

    Not trying to be flippant but if that's truly the case I would look for a new tech.

    Well, I was half right anyway

    He (the installer) claims to have tried to install 8.1 with my product key but, that it was an "Upgrade" key and, the activation refused the key.

    I don't know how hard the installer tried or whether he gave up too easily as I still don't know what to expect

    Can you load 8.1 on a "New" system with an 8 "Upgrade" key?

    The 2 Windows 8 Pro packs I bought seem to be "Upgrade only"

    Does this sound reasonable? In all the reading I have done this concept didn't present itself!

    I am picking up, what I assume, will be a blank desktop in an hour and then MY adventure will begin.

    I will follow various threads from this excellent forum and try to get, first, 8.1 to load.

    Failing that I will try to load 8 then update to 8.1. Failing THAT I will try Windows 7 then update to 8 then update to 8.1

    At this point I hasten to add that I have legal (bought and paid for) keys for all the Windows 7's and 8's I am using or attempting to use. (except 8.1!???? but that is free????)

    The whole "adventure" frightens me as I will try to use/setup RAID and EUFI....

    I would welcome any encouragement from members of this forum but, I suspect, a couple of hours from now my "adventure" starts and it will be too soon to get any encouragement

    People around me are just waking up and people further away are getting ready to go to sleep

    Yes, I've done it a few times.

    I downloaded the iso for 8.1, installed using the generic key which can be found on this site then changed key and activated.

    I picked up my new desktop and it had Windows 8 (not 8.1) installed. Entered my code/key and off it went.

    It appears to have RAID (well IRST anyway) loaded, I don't know if by intent or accident? I don't know how UEFI stands? The BIOS is UEFI but I don't know how Windows stands with UEFI? I tried to create a UEFI BOOT USB but had some problems

    I'll have a play, try to create a 4Tb mirror. See if I can port a mirror from my old system etc.

    Maybe time to put the thread to sleep?

    Thanks for all the replies...
