License changes in Windows XP SP1 explained

WinInfo | at | by Mike

Microsoft licensing guru Allen Nieman dropped me a note about the licensing changes in Windows XP Service Pack 1 (SP1), which will ship soon. Here's Allen's succinct one-paragraph version of the announcement:

"Microsoft will introduce additional technological measures in Service Pack 1 for Windows XP aimed at ensuring legally licensed customers receive the full benefits of owning their valid license. These changes include denying access to the Windows XP SP1 updates for PCs with known pirated installations, product key validation during activation, and the repair of cracks to activation. Additional features have been added to provide a better customer experience including an additional three-day grace period to re-activate after significant hardware changes and the ability for volume license customers to encrypt their volume license product key in unattended installations."
