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
