Updates are a double edged sword. On one hand they are needed, as no code is ever perfect (considering some vulnerabilities are discovered on Win 10 that have existed since the 9x yrs, the joys of having robust support for older software) , but on the other hand a lot of ancillary stuff is added to it.
Unfortunately, with Win 10, it's not quite as easy as it was with earlier versions. Even some hacks that I knew with the registry are no longer valid with later versions of Win 10 to stop updates. Bare in mind, with the rolling release nature of Win 10 (which also means that Win 10 is in a perpetual state of beta), older versions are no longer support and may no longer be supported by your software vendors as well. So while you may have Win 10 on your computer, if it's so old (>18 months), it more then likely is no longer supported. So there is a need to always be updated.
Even Win 10 Enterprise is more aggressive with the support for individual versions.
These issues seem consistent with graphics card or related graphics driver issues. If you have a graphics card (not onboard graphics) try removing/reinstalling the latest drivers
My dad was actually having the reverse issues with some of his cards in that Windows was installing the latest drivers that didn't quite work right with his card, so he had to regress to an earlier version.
