1. Install Windows 7 without any product activation key.

3. When the activation grace period (or evaluation trial period) is almost expired or ended, log on to Windows 7 desktop, and open a Command Prompt window (i.e. type Cmd in Start Search and hit Enter ).

4. Type any of the following commands into the command prompt, and then hit Enter :

sysprep /generalize
slmgr.vbs ¨Crearm
rundll32 slc.dll,SLReArmWindows
slmgr /rearm
5. Reboot Windows 7 to enjoy another 30 days of free usage without worrying about activation

6. When the activation grace period countdown timer almost running down to 0 again, repeat the rearm trick to enjoy another 30 days of Windows 7 for free. User can run the rearm command for maximum of 3 times.
As rearm only works for 3 times, make sure the command is only been run when the 30 days countdown of evaluation period is almost expired.

That's 4 months more than enough time for someone to save up and buy a key.
