Windows updates issues can be difficult to fix at times, considering that the windows update engine is an integral part of the windows operating system.
Sometimes, its easier to do a system restore. Please note that a system restore isnt the same as reinstalling windows. With a system restore you wont lose any pictures, music, files. And the only programs you would lose would be programs you installed after the restore date we choose. And if we dont like what the system restore does, we can undo the restore and put the computer back just like it is now, by clicking undo restore.
So lets try this as a first repair attempt. As its an effective repair that has little downside.
Click start, all programs, accessories, system tools, system restore..
Click, restore my computer to an earlier point, then click next..
We want to choose a restore point that was at least one day before the issues started.. To be safe, go back a couple of days before you think the problem started. Or even a week.
Carry out the restore. the computer will restart.
Then, try opening and running windows update and see if it can check for and download updates. Let me know the results when you can. And whether this works or not please send a reply so that I can either continue to assist you, or so we can mark this issue as resolved.
