There've been a thousand and one ways to get your hands on Windows Vista SP1 or various beta versions over the past few months. But Microsoft is set to post the manual installer for Vista SP1 on March 18. If you're not in a hurry, you can wait until April when the update will be available through the Windows Update service.

In other news, Microsoft has confirmed that Vista's successor, which goes by the clever codename of Windows 7, is on track for a 2010 release. We've heard a lot of dates over the last few months, ranging from 2009 to 2011. But Microsoft has consistently said Windows 7 was part of a 3 year cycle. They just didn't really make it clear when the 3 years started. Apparently the answer is, 3 years from the time Windows Vista shipped to consumers. Not the date when Vista development began, or 3 years from the date it was shipped to manufacturers.

Does that mean we'll see a public launch of Windows 7 in January of 2010? Eh, maybe. On the one hand, a lot can happen in two years. On the other hand, when you're trying to retool an operating system as widely used as Windows, you want to spend as much time as it takes getting things right, otherwise you wind up with... Windows ME. What, you thought we were going to make a dig at Vista? How little you know us.
