Error Code 8000FFFF when trying to update windows (windows 7 64bit)

I just received th error code 8000fff. My computer runs very tight, its used specifically for gaming and email. System was running perfect but noticed there was windows updates to install. Did the update a few minutes ago and all updates failed to install. Along with the update install, for whatever reason it turned off windows defender and im being prompted to turn it back on.

WIndows Spec:

windows 7 64bit ultimate edition build 6.1.7601 serive pack 1 build 7601

virus free not antivirus or internet security programs

Ran "microsoft safety scanner and malwarebytes" no issues

firewall is configured correctly

system running fine until doing windows update



Core 2 Quad Q6600

8gb 1333 memory

gigabyte motherboad G41 chipset

Geforce GTX 460 1gb

velociraptor primary HD (HD temp 29c)

hitachi secondary HD (HD temp 30c)

*not running in RAID"

CPU temp: 41c

GPU temp: 35C



IE 9

Version ( 9.0.8112.16421)

update version: 9.0.3 (KB2586448)


Here are the install items that failed to install.

update for windows 7 for x64 based systems (kb2633952) fail

security update for windows 7 x64 based systems (kb2619339) fail

It looks like it went and tried to install it twice as well. It shows double entries in the install history.

Again, this was a standard click on windows update through start menu for windows 7 64 bit. No issues prior to this system was running fine.

I did go to this url from the windows 7 information page and installed this fix

Since then my system is running slowwwww im going to do a restore but would like to know why components failed to install, all except the malicious tool . It also turned off windows defender which now wont turn back on.


UPDATE: I did a system restore. The restore point that was set automatically before the above FIX would not restore at that point, said corrupt. I had to restore from a point 2 days prior. System is back running fine, but have not attempted to update my system until i know what happened or what is wrong.
