Same 'rearm' command that worked for Vista extends activation-free grace period

Computerworld - 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.
Microsoft allows users to install and run any version of Windows 7 for up to 30 days without requiring a product activation key, a 25-character alphanumeric string that proves the copy is legitimate. During the 30-day grace period, Windows 7 operates as if it has been activated. As the grace period shrinks, however, increasingly-frequent messages appear on the screen. For example, on days four through 27, a pop-up asks the user to activate once each day. During days 28 and 29, the pop-up displays every four hours, while on Day 30, it appears hourly.
But by invoking the "slmgr -rearm" command at a Windows 7 command prompt, users can reset the time-until-activation to 30 days, said Woody Leonard, a contributing editor to Windows Secrets and the author of several computer books, including Windows Vista All-in-One Desk Reference for Dummies.
"You can run the -rearm trick a total of three times," said Leonard. "If you perform a -rearm at the end of each 30-day period, you end up with 120 days of full, unfettered Windows 7 use, without having to supply an activation key."
