Microsoft s first Patch Tuesday for 2010 will be very light: A solitary bulletin addressing a vulnerability that is rated critical only for Windows 2000 users. The bulletin is rated low for every other affected version of Windows, meaning it is extremely difficult to exploit or has minimal impact. In addition to Windows 2000, the issue affects all Windows versions, including XP, Vista and the newest Windows 7. Microsoft says a known SMB denial-of-service issue will not be fixed this month.
