Recently the 180 Day trial of my development Windows 7 Embedded install expired. This necessitated that I attempt to reset the Grace Period.
The following seems to work;
- Open Command Prompt under Elevated Privileges
- Enter “slmgr.vbs /rearm” and press Enter
- Wait for the command to complete, and ok the dialog box
- Restart your system
- Windows should prompt that it is not genuine
- Open Command Prompt under Elevated Privileges again
- Enter “slmgr.vbs –atp” and press Enter
- Ok the Dialog Box
- Restart Windows
- Goto your System Properties
- The machine should now have 180 days once more
