We've heard a few reports about problems customers may be experiencing as a result of KB937287, the servicing stack update I blogged about last week, and I wanted to provide a quick update for you. Immediately after receiving reports of this error, we made the decision to temporarily suspend automatic distribution of the update to avoid further customer impact while we investigate possible causes.
I had issues with this particular update (KB937287) on a Vista x64 machine. It wouldn't install from Windows Update. I looked online to see if others were having the same issue and found that several were.
The solution was simple. Manually download and install the update.
I'm sure that will be enough to confuse many users though. MS needs to find a way to get that update to work properly via Windows Update or it will cause a lot of problems.
