But, SFC will only find Wndows problems that are due to corrupted files, right?
I am not sure, what else it does.... but yes it does check for corrupted or missing files in Windows system files and it tries to fix them by replacing the older version of the file or if it can not repair then it will let you know that there are some problems
that could not be fixed.
Corrupted files in windows can also cause windows crash and slow it down ... so it is a good idea to check once a month if you install unknown programs or surf web alot.
For this particular problem, it looks like the problem is caused by windows update... therefore the sensible thing to do is to uninstall any recent updates or use system restore to go back if you know which one caused the problem.
Also note that uninstalling updates might fix the problem problem but I personally think is that you have make sure that is not caused by third party software in first place otherwise you will face problems in updating your system later.
Uninstall unused third party programs installed on your new pc, get rid of unused toolbars, any other software like Sonic player on vaio computers, bing toolbar, evernote, etc. if you don't use them why keep them, just get rid of them.
Have a look a this thread, someone found a solution without uninstalling windows update:

And there are loads more, just search in the forum, see which one applies to you?
You make some valid points, but if I were to run SFC and get a 'no corrupted or missing files' result, that clearly does not absolve Windows as the culprit.
