The thing that led me to your site, was the inability to update windows. I had tried everything. Any scans I attempted I did in safe mode and came up with nothing. There was nothing anywhere that would let me update Windows. I tried every suggested to fix or tweak, or reinstall this, or that, nothing worked. It wasn't that I would get an error, it would just not load and would eventually timeout. So I decided to try your site.
I'm running Win 7 Premium. I followed everything to the letter! Did the chkdsk /f on restart and it came up with nothing and I did sit and watch, and there were no bad sectors. When my computer kind of crapped out (very slow, could barely load a web page and very delayed response when I clicked on anything, like task manager, control panel etc. I ran some more scans in safe mode with other tweaking programs. I did finally manage to get better speed and response. I tried again to update windows..nothing, nada, it would not update and felt very much like that's it, computer is done. I use this desktop for work, I work from home. Then I did something I'd been avoiding...
I went to Win 10 Update and damnit I did not want it. I have it on my laptop and hate it. Anyway, it took the update immediately! I feel like I am being forced to upgrade!
