Hi,
Five years on and this has not been fixed by either of the two huge corporations involved, instead people need to roam around like homeless beggin for some food, pathetic!
I write this and thank everyone who made the effort to solve it. Here is my take in case is of any use to anyone.
My problem started with a Dell Studio XPS, HDD (500GB) about to blow, replaced it with 1TB, Computer worked but many things didn't, Windows update, troubleshooter, I couldn't download anything with IE etc, etc.
I have tried just about everything suggested here, first what was suggested by the official Microsoft employee, the file checker worked but there were things it couldn't fix. Tried the FixIt link it run through but made no difference I even run several tools
provided externally from this forum but most of them didn't work they just got stucked at some point I presume because of the same problem. Quite early on it was clear to me that the Intel matrix was being pointed as the culprit but despite all the attempts
I wasn't able to update it. After many hours wasted I went to: control panel>programs and features>Intel matrix storage and uninstalled. That did it for me, while I haven't tested it thoroughly all the problems that were driving me insane seem to be gone and
since I have no RAID on this computer I think I am not going to miss it at all. Hope this helps!
