After installing Windows Operating System using this tutorial , your Windows OS should be "Windows License is Expired".
Once your build reaches the license expiration date, your computer will automatically reboot approximately every 3 hours and the windows will no longer boot, 2 weeks after the license has expired.
So if you want to test the windows, you can use trial license on your Windows for 5 times by following this steps :
- Open Windows Powershell in Administrator mode ( Run by Administrator )
- Restart the system for the changes to take effect
Congratulations your trial windows license is extended for 180days (6 month).
If your windows license expired again after 180 days, you can extend it by
slmgr -rearm again on Windows Powershell.
180 days x 5 = 900 days (approximately 29 months!)
