what do update numbers mean?

Hi,
Is there a way to check out Windows updates using the number eg KB2630937? Since I downloaded a batch of updates last week I am having a weird problem and I want to see which update might be responsible but just having a long list of numbers tells me nothing. I have looked on the Windows forums but if there is an answer there I am too thick to find it so I come to the experts.

 

And, to go along with the above, you might consider restoring to a point before the updates to clear up the problem, then configuring WU to download only, and selectively install until you find the culprit.

 

KB2630937
(K)nowledge (B)ase, so you can look them up at Microsoft support.
http://support.microsoft.com/search/?adv=1

 

As already posted, KB = Knowledge Base, but the number you show seems not to be a valid one.

A valid KB number, e.g. 2345886, can directly be appended to the URL support.microsoft.com/kb/ → http://support.microsoft.com/kb/2345886/ and it will give you all the information about this particular KB article.

 

thanks everyone, lots of avenues to explore. the number I quoted was just an example, I have about 25 to check out. Poor me
