Extend the Windows Server evaluation period
Rearm a genuine evaluation with slmgr. This is not a substitute for a license.
Evaluation images stop serving after the trial clock runs out. Microsoft allows a limited number of rearms.
Check remaining time
Open an elevated Command Prompt and read the rearm count and expiration.
slmgr /dlvRearm
slmgr /rearmReboot, then run slmgr /dlv again. When rearms are exhausted, install a retail, volume, or SPLA key you are entitled to use.
If the VPS already stopped
You may still get a console or safe-mode path from the client area. Rearm, reboot, then activate properly. Random shutdowns are often this clock, not hardware.
Licensing
Noble VPS provides the VM. You are responsible for a valid Windows license when evaluation is no longer enough.
