Windows 7 users, were there a pack of 13 updates Oct 12, 2011?

Last night when I tried to shut down Windows 7, I got the typical looking notice to not power off till Microsoft updates were installed. The only unusual thing was it said 13 updates—which is quite a large lump for one sitting.

This morning, it was still churning on #2 of the 13, obviously lost in a loop. I did a buss interrupt and told it to boot normally, and it did. But I am wondering if Microsoft really sent out 13 updates yesterday, or is it time for me to run a complete virus scan. Other Windows 7 users, did you get a large pack of updates yesterday?
