For security I use windows defender and malwarebytes and I have disabled windows updates along with 'automatically install drivers from manufacturers'.

That's was quite a good way to get rid of people who only upgraded gpu's 7 years prior to that and still had only 5 fps less rather than invest a 500 dollars for a cpu+mobo+ram upgrade for 5 fps more, taking into account most at that time still used 1080p 60hz displays. Remember with the 'backdoor' in intel cpus older than 2019 etc etc, then microsoft came up with a patch that crippled performance by up to 90% if you don't buy a brand new cpu etc etc. I also believe that farce intel+microsoft invented is a lot to add to that. They had generally terrible performance considering their powerful pc's. I have seen dramatic differences in game performance at people with newer versions and a lot more powerful pc's than me, at the time. when I install net framework 3.5 on my pc, the installation process is completed successfuly but at the end there is a setup error saying an error occurred.

Because 1607 was always working flawlessly for me.
