Windows 7 states not genuine Win7 boot after moving partition


For some reasons after playing with disk partitions Windows 7 thinks System partition label was changed (for example from C: to V:).
As a consequence Windows now thinks that your installation is not licensed... 


And here's a very simple solution that saved my day.

  1. Hit control-shift-esc to get the task manager and ran regedit
  2. Navigated to HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices, backed up and removed the data inside
  3. Reboot

 upon reboot, the system will checked the key again and validate the license.
