In a project, we have lots of Windows user that have bought licenses for 1 month, 2 month,... 1 year and so...
CURRENT SITUATION (WHAT I DON'T WANT):
When users are created and added to the OS, a solid expiration date is given.
WHAT I WANT:
Users' expiration date should be calculated automatically after first login. The user might not need his account right when purchases the license.
In another words:
When a license is purchased at Jan 1, he should use the license until Feb 1. No matter whether he really logs in or not. He cannot come Feb 5 and begin using his license because that has expired then.
What I want is that when he comes at Feb 5 and begins using, the license update until March 5.
Environment: Windows Server 2012
