When updating Windows Pro 7 to Windows 10 activation may fail. The name of the university KMS-server has also changed a few times, making Windows computers using the old name get unactivated.
It may look like this:
slmgr.vbs /ato should
try to do an automatic activation if the computer is part of the
Active Directory. If it is not part if the Active Directory you need
to specify the KMS-server, see below.
slmgr.vbs /skms kms.user.uu.se and then
slmgr.vbs /ato again.
/dli. It should look like this:
-type=srv _vlmcs._tcp.user.uu.se. If that is the case, the
address kms.user.uu.se should be changed to the new one. Please
send mail to firstname.lastname@example.org to let us know
if this is the case. In the example below both reference to the same
server which is correct.
