Okay, I installed the System Readiness Tool, and I finally have a CheckSUR.log file to give people, diagnosis : wow, there's about 70 000 lines of issues in there, there was no CheckSUR.log in the CBS.log file I had uploaded.
I'll be uploading that here, this is the last chance before I decide to reinstall. snick, my windows 7 x64 ultimate disc doesn't allow me to make a Repair Install, when I click setup.exe after extracting the iso contents, I only get a Windows 7 header with an Install button, nothing like the image shown in the guides.
Since I've seen that Installed Updates is almost empty and a program I need, needs .NET 2.0 and that fails to install because it says I must use the Turn on or Off Windows Features thing, and surprise, that turns out to be empty too now.
I think the malware I picked up (firefox hijacking) a little after KB4474419 failed again and again, sometimes, I don't know how, I have ESET NOD32 antivirus and malwarebytes, the thing was really difficult to get rid of, and I think it infected some very important files, I remember reading CheckSUR or such and other stuff in system32 I had to quarantine out, no way to clean up the files, then all my issues showed up, I had to use malwarebytes, zemana anti-malware and malwarebytes adware to clean it all up, it took a while to find somebody who had a guide and who was aware of that old school browser hijacker (it only did so on Firefox strangely, didn't touch IE11 or Iridium). But I definitely lost some critical files or else things wouldn't be this messed up.
So I'll be attaching or giving a link to my CheckSUR.log file, I think that will tell those who really know what's up with those kind of files what's going on here. Also, even downloading updates I had installed, in Windows update where one sees one's history of updates...everything is there and installed fine, yet after using the Win Clean-Up tool, things got better (much faster and more stable OS, but it screwed up other things, I guess to balance things out

, trying to get an .msi file of an update I already have installed according to my history will give me dialog box saying "This Update does not apply to your computer".....I don't think that's the normal message one gets when trying to install an update th Caat is already present, now is it? Can't install basic things like .NET 2.0 because said tools are blank, which makes no sense. To be clear it is thee Installed Updates window that is practically empty, there's .NET 3.5, silverlight and that's about it, it's nonsensical.
Hope I can finally close that thread soon after someone take a look at this, I'm seeing it definitely has to do with updates, WUT did not help, so maybe something will click here, I found out what's causing the update issues big time. It's strange how I can still manage to do a lot of things, the system doesn't act broken at all, except when certain native windows features are messed up such seemingly all .NET packages disappeared except for 3.5, hopefully it hasn't cleaned itself up of all the updates I've done since this install, about a year 1/2 ago.
