So are you the type that will immediately download it, cross your fingers, get out your lucky rabbit foot and hope for the best?  Or will you be waiting a few weeks to see if this Service Pack causes more issues than it fixes?

In a blog post, Windows Vista product manager Nick White acknowledged having encountered driver compatibility problems with the initial deployment of SP1, though at this point those problems aren't exactly news.

"We spent the last couple of months looking closely at reports of driver problems on pre-release builds and, to be safe, we held the public availability until March," White wrote. "We've completed our analysis and are happy to report that many of these issues were fixed between the release candidate (RC) and the final version. We identified a small number of device drivers that may be problematic after an update from Windows Vista to Windows Vista SP1."

The download is available via Windows Update or you can download the standalone version here.  But be prepared if you do the manual download that it is larger than the Windows Update version, it comes in at a whopping 434.5MB!  That's right, close to half a gigabyte!  So if you are the bleeding edge type and decide to download and install it now then leave us comments here on how it goes.
