Short story: I made use of a Win10 AIO with gVLKs inserted. Installed Pro edition and slmgr -xpr> volume activation will expire... How can I change it to get a permanent activation? (The free upgrade permanent activation). Already tried slmgr -rearm so Windows got not activated status but from that point I couldn't go further, couldn't activate it permanently. Long story: 1. I know this genuineticket.xml procedure although never played with it. 2. The "normal" upgrade process is very well known to me, I think... 3. I get a PC (not mine) which allegedly underwent precisely the normal upgrade process, from a Loader activated Win7 Ultimate to Win10 Pro (I was not aware to be honest just believe what the owner told me). So supposedly it had to have a permanent online activation. 4. As the system was unbootable and I don't want to waste time because he wanted a clean installation anyway, I decided to format and install Win10 Pro using my Win10 AIO with gVLKs inserted, syspreped, etc. on every index and I believe this is the problem. I tried two times reinstalling Pro version from scratch but slmgr -ato always said "volume activation will expire...blah blah", it was KMS activated. 5. Fine, I thought. I believe just slmgr -rearm then activate online again will suffice, but it didn't. Then I started this topic. To find a solution to this specific activation problem. Unfortunately while expecting an answer from you guys didn't come sooner and I decided to undergo the full upgrade process. 6. I installed Win7 ultimate, loader activate, online validation then upgraded with my AIO, wham! KMS activated again. 7. I restarted once again with Win7 ultimate, loader activate, online validation then upgraded to Win10 but this time using an untouched iso... That did the trick. Now permanently activated. 8. The point here is how to fix that activation problem, change it from KMS to online permanent digitally activated Win10 without reinstalling.
