KB978601, KB979309, KB981332, KB980232 & KB979683 were the five security Windows Updates for Windows 7 that were sent out on Tuesday, April 13, 2010.
I waited until today to see if there were any reports of folks having trouble with these. Didn’t see any reports, though I will confess I didn’t look that hard.
I took a risk. Bit the bullet. Installed all of them.
It required a restart. I am posting this, from my Windows 7 machine, after the restart. I am still alive … I think. << smile >>
It seems OK. So if you are vacillating, give it another 24 hours and then go ahead. I will keep you posted.
Good luck. All the best.
