Do you remember when the last time was that you were able to install updates?
if so, please try the following as it should fix the issue
Click start, all programs, accessories, system tools, system restore..Click, restore my computer to an earlier pont, then click next..We want to choose a restore point that was at least one day before the issues started..Carry out the restore. the computer will restart, then let me know if that fixed the issue or not..

What we may need to do then is called an in place upgrade of windows 7, which wont erase your files.
Do you know if you have windows 7 home, Windows 7 professional, WIndows 7 basic, etc?
Also, is service pack 1 installed?
In the meantime, lets try to run the windows update troubleshooter which probably wont work, but its worth a shot
Download that, open and run it and see if it can fix the issue with your updates.. if not, I need to know the version of windows 7 you have.
I can help you create a legal windows 7 pro sp1 reinstall cd, t hat we would use for an in place upgrade install ( keeping all your files and programs intact when done correctly)
but lets give the update troubleshooter some time to work.. Lets say, 15 minutes from now.
If it hasnt errored out or shown any updates to download, we can close it and proceed with the upgrade install .
If it does start downloading updates or finds them ( showing the problem is resolved ) let me know!
