Be warned you will need to re-enter your activation key and reactivate Windows using this process (not a big issue if you are using a KMS key).
Wouldn’t it be nice if there was a sneaky fix to reset the rearm counter Well there is. The script is interactive and will tell you how many days are left (very handy as you can look it up extremely quickly this way) and lets you choose if you want to reset the time or not. At least in Windows 2012 this problem has been mitigated as the rearm counter is now set at 1000.
To use the script, simply save to your RDS server and run in an elevated PowerShell prompt. I have tested on Windows Server 2016 and it definitely still works. But they no longer test or maintain the script. In the Windows Server 2012 and Server 2012 R2 era, Microsoft provided the following PowerShell script for this scenario. For whatever reason, you may end up in a situation where you need to extend the grace period for Windows RDS server (remote desktop services, aka terminal server.) This can be a pain, especially if things time out and you lose RDP access to the server.
