Hi Susan. You might be right in saying that KB3022345 doesn't actually corrupt any files, only that it produced an erroneous report of corruption, if I've got it right - I'm a layman but as a user. this is what happened to me:
My Compaq Presario CQ71 had been hanging up at shutdown and there had been occasions when I've had to start in Safe Mode and use System Restore to get back on track.
My first source for help was the HP Update Help Centre and I installed an updated BIOS but it happened again. I lost internet connection, Windows Security and System Restore. I sorted it using system restore via system recovery at the Esc phase of powering
up. Running Got The Power's fix resolved my problem.
Using any search engine, input "KB3022345 problems" and there are hundreds (at least) of Joe Public, Microsoft customers logging the problems that they've had.
I do not want to interfere in an interesting debate between two experts but may I ask you one question - when these problems happened, I had a message saying that details of the problem would automatically be sent to Microsoft, (That's the usual procedure,
isn't it?)
So will Microsoft tell us how many of these 'problem reports' from users have Microsoft received and what have they done about it?
I still remember the Microsoft up date that (temporarily, thank goodness) killed my XP tower. It was caused by some programmer forgetting that some PCs had amd processors and so the "for Pentium machines" update was disastrous.
You are totally correct in saying a major problem now is that ordinary users such as me have lost all faith in Microsoft. My XP is useless, my Win7 has a limited shelf life and WIn10 is being slowly forced on me - including removing the choice of control
over updates. Sorry for the rant, and for going off-topic but just search the web for "KB3022345 problems" and you'll see what the 'man in the street' is going through.
