The others who have posted advice are far more expert than I am.
And each computer is unique -- problems that sound "the same" often turn out to have different causes/solutions.
However, there have been MANY MANY folks at another forum that specializes in Windows 7, myself included (on 2 Win7 boxes), for whom not only KB3020369 was needed, but (most importantly) ALSO KB3172605.
The trick is to break the endless updating loop so that you can get these 2 patches to install manually.
If Windows is already "stuck" in perpetual "checking for updates" you may need to not only change to "never check for updates", but also temporarily disable Windows Update from services.msc.
I'm on my Win10 box at the moment, but this the basic procedure:
First, change Windows Update (temporarily) to "never check for updates".
Then, you might need to also do the following:
- If you have not already done so, download & save (but do not yet run) KB3020369 and KB3172605
- From the Windows start orb, type "services.msc" (no quotes).
- Scroll down to Windows Update service
- RIGHT mouse-click on it
- Change it to "disabled" and the "stop" the service, click "OK"
- Reboot the computer
- Run KB3020369, reboot
- Run KB3172605, reboot
- Go back into Windows update and reset it back to enable checking for updates (most of us use "let me choose...")
- Go back into services.msc and change Windows Update back to "automatic-delayed start"
You ought to now be able to run a manual Windows "check for updates" and things ought to work OK.
This has worked for me (two different systems) and for many, many other folks.
NOTE: For a fresh Win7 install, you might also need KB3125574 FIRST, and then the other 2.
YMMV, but if this does not resolve the issue, then it's likely a different problem.
