The key to extending the grace period is a command-line program in Windows 7 called
Software Licensing Manager (SLMGR), which is actually a VBScript script named slmgr.
vbs. (It can be found in c:\windows\system32 by default.) Using this script with the -rearm
parameter, you can reset (or, in Software Licensing Manager lingo, “re-arm”) Windows 7’s
30-day activation grace period. This effectively resets the clock on the activation grace
period back to a full 30 days whenever you run it.
You can run this script successfully only four times, (30 days of
initial grace period plus four additional 30-day grace periods).
1. Open the Start menu, select Search, and type cmd.
2. Right-click the cmd shortcut that appears and choose Run as Administrator from
the pop-up menu that appears. Windows 7’s command-line window appears.
3. Type the following text in the command-line window and press Enter
slmgr.vbs -rearm.
When the command is run successfully, the Windows Script Host window appears
“Command completed successfully. Please restart the system for the changes to take effect.”
Click OK to close the Windows Script Host window and then restart the PC. When
you reboot, reload the System window. The grace period has been reset to 30 days.
To get the system window, Right click the My computer and click properties, the lower side of the window has the activation section, there you get your Activation status.
