Install Windows 7 without the product key.

After installation has completed, start regedit.exe and navigate to:

HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/CurrentVersion/Setup/OOBE/

Change MediaBootInstall from "1" to "0"

Quit regedit.exe and start the command line utility with administrator rights (enter cmd into search, and right-click it — choosing Run As Administrator).

In the command line window, type: slmgr /rearm

Wait for the Command Completed Successfully notification.

Reboot.

Run the Activate Windows utility.

Enter your product key.

Cross your fingers for a successful activation confirmation message.
