I have gone back and forth, three times with installing, testing, then using restore point to go back before this installed update: 2019-08 Cumulative Update for Windows 10 Version 1903 for 64-based System (KB4512941). This update is slowing down windows. After installing, I click on a short cut on desktop, it takes windows 15 seconds to start it's loading circle. My web browser is ok but my web clients are affected (Steam,Origin, Arc ect..) When I use my restore point and go back before the installed update, they work normally again. What I have not done yet is use Uninstall update in settings and bypass it, kind of don't want to do it for it's importance but afraid I will have to because it is insanely annoying.
I am currently in touch with microsoft about this issue.
