UPDATE 2/21: When calling 1-866-PC-Safety - be sure to let the support agent know you are calling in reference to a Windows Update issue. Also: Microsoft has released KB949358 containing information regarding the issues related to KB937287.
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.
So far, we've been able to determine that this problem only affects a small number of customers in unique circumstances. We are working to identify possible solutions and will make the update available again shortly after we address the issue.
Customers who may be experiencing this issue can use system restore to correct it or contact 1-866-PC-Safetyfor help troubleshooting. Additional guidance will be available via Microsoft's free Update Support Center soon.
