I checked my windows 7 pro 64bit which does NOT have ie 10 (i found too many problems trying to install it on several ie 7 machines, i think it is actually made for windows 8), it did not have this problem but I uninstalled the kb anyway just in case but:
I just purchased a windows 7 pro 64 bit computer for a business client of mine. The computer is 1 week old. It is in my lab right now getting all its needed programs and updates, I plan to bring it to the client next week.
I installed 46 Windows updates on it prior to yesterdays. This Optiplex came with ie 10 installed already.
I did the updates yesterday. After looking at the posts here and on the Windows Update Forum site I decided to turn it on this morning. I had shut it down after I did the last update and reboot.
I was planning on turning it on this afternoon to work on it anyway
When I turned it on, everything was crawling along. IE 10 just sat there loading. Office 2010 sp2 took 10 minutes to load
Firefox would not load at all.
So i went and uninstalled the KB
After the reboot I prayed- mind you this is a brand new machine!!!
IE 10 now opens fine, Office opens fine and Firefox loads
And everything else seems fine
I do not know if there is a problem because ie 10 is installed, my other computer has ie 9
I will tell you I installed this kb on 3 windows 8 computers and 2 windows 8 tablets- no problems
Seems it is a Windows 7 issue
