Windows 7 will run 120 days for free

Like its predecessor, Windows 7 can be used for up to 120 days without providing a product activation key, Microsoft confirmed today.
Although Microsoft generally touts a 30-day time limit for users to activate their copies of the company's operating system, a little-known command designed for corporate administrators can be used by anyone to "reset" the countdown up to three times.
Late yesterday, the Windows Secrets newsletter published step-by-step instructions on using a single-line command to add an additional 90 days to the stock 30-day grace period.
