For several days now, I've been told that three "Important" updates are available for me to install on my Windows 7 64-bit desktop computer. I went to my spreadsheet of PatchWatch info, and found none of them listed. One was a Silverlight update from 5/22/2012. Perhaps that's too recent for the May 23 issue, but the other two updates are much older. One is KB2538243, which carries a 1/24/2012 date. The other is KB973685, which according to the Updates description carries a 7/12/2011 date, which is before I started to make my spreadsheet. I did searches on the Windows Secrets site for all three updates. Two searches came up completely empty, while the third, for KB973685, returned a hit from a PatchWatch column dated Dec. 10, 2009, a year and a half BEFORE the date given by Windows Updates! Ultimately this hit failed to give me any useful information.
I'm confused. I had thought that Patch Watch covered all Critical and Important updates, but that seems not to be the case. I might add that this is not the first time that I've received Important or Critical Windows updates for which I could find no mention on Windows Secrets. How am I supposed to know what to do about such updates? Are there other reliable places where people turn for information? What determines whether an update is covered on Patch Watch?
I'd be most grateful for any information people care to share. Thanks in advance.
