I'm only going to install programs from Microsoft, not from some random source. However that Diagnostics tool shows an error: Windows Update error 0x80070490(2016-05-11-T-01_59_11P). I think this is the same error as last time. These Microsoft diagnostics
and fix it programs can't seem to fix the problem, so why even bother running them? Also, after running the Diagnostics tool updates show "never" as if no updates were installed, but they are there.
You can't turn off updates, because then security is compromised, as if it wasn't bad enough on Windows in the first place.
