Windows Important Security Update Error

Hi,

I have a problem with updates that try to install every time PC restart.
They give me everytime error code 80070490 and if I try to press Try again then give me error code 8024AFFF.
I try to solve the problem with Microsoft FixIt, then update was installed succesfully, but after restart they try to install it again (everytime the same update) and give the same error.

I found some solution on the net that not work for me:
1. Windows Update error 80070490
2. Error code 0x80070490 when you use Windows Update or Microsoft Update to install updates
3. Code Error 80070490 checking for Windows Updates - Microsoft Community

I not use first option becouse I not have original DVD, I have a PC with preinstalled system Windows 7 Home Premium.

Anyone have any ideo how to solve this problem?

Since it's 18 hours since you posted this with no response, I'd say it may be because you didn't provide the info that this forum requires. Run the SURT program, the sfc scan, and post the logs that are requested in the instructions found here:

Hopefully then you get a better response. I'm new here too and just learning the ropes, BTW.
