We all know that we can use Windows 7 without entering a product key for 30 days. But do you know that the grace period until activation can be extended to a maximum of 150 days?
There is a way to do this and note that you should use this method when you have 2-3 days remaining for product activation as this method can work for a maximum of 4 times (30 days + 4 X 30 days = 150 days).
Here you go:
Open the Start menu, select Search, and type cmd.
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.
Type the following text in the command-line window and press Enter when complete:
When the command is run successfully, the Windows Script Host window appears, noting “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.
