Please help me explain2. If the key not original, is there any way for i to buy the volume license from Microsoft, i meant not from 3rd party or Microsoft partner. if yes.. please help me provide the contact of Microsoft overseas s

Win 10 activation is expiring - volume license

Finally got it activated but still confused as to what is really going on with activation.

here is what I did:

-got another Win7 Pro key from a friend (non volume license one)
-I tried to activate it, but it gave the same error message as before, "could not activate with this key"
-following suggestion above, I tried it a second time. This time it activated !!! (internet was connected both times)

don't know why just doing it 2 times makes it work. maybe someone else can explain that.

I checked it with ShowkeyPlus and to my surprise it now said it was activated and showed the installed key as the generic Win10Pro key that is listed in above post. But I did not enter that key. ????

 

windows 7 volume license if i use this volume license to activate a windows 10

Win 10 activation is expiring - volume license

I was able to replicate the error using aVL install media





Then using a Win 7 Pro COA key --

-- I got the 'key is not valid" error code 0xc004f050 before internet connectivity was established




Subsequently it activated on a 2nd attempt with internet connectivity

Licence channel changed from this...




... to this.




The error message is misleading regarding the validity of the Win 7 key.
