Meaning/importance of my SFC/Scannow errors in CBS.log & are they problems fo

Many, many variations of what seem to be the “errors”. See examples below for full text, but this CBS.log file is after successfully running “Dism/online/cleanup-image/scanhealth”, chkdsk/F, and sfc/scannow (many, many times). Have tried safe boots, and using windows 8 disk for “automatic repair”. In the CBS.log, I get 100s of: “DIRSD owner warnings”, “ignoring duplicate ownership”, “cannot repair member file [various *.Json files]”, and “failed to open [what appear to be windows update agent] packages”. How important are these errors and how fix? When I try to upgrade to Windows 10 in next weeks, will it “solve” these problems, or choke/crash when trying to upgrade? Other than these error messages, I am able to use my computer and many applications fairly normally. There are two exceptions, that are either clues to the above or are symptoms of the above. Real problem 1: When I reboot, my system will freeze sometimes about 10 seconds after Windows is opening all of its various processes. When I do a hard reset, sometimes the situation repeats, in which case I do a second hard reset. Windows always works fine after these resets. I am guessing that a delayed process is causing this but in searching have not come up with a clue. Real problem 2: I am able to use Logitech’s wireless keyboard and mouse, but no other keyboard and mouse in Windows. When I boot to the Asus UEFI bios utility ALL attached usb (wired and not wired) mice and keyboards work. Have spent 2 full days fiddling with Device Manager USB and HID drivers, updating, uninstalling, etc. to no effect. Have fiddled with Asus z87 MBO settings, incl USB, to no effect. My main question is that since I can certainly get by until Windows 10 arrives, will that “solve” these problems, or will all hell break loose. I really, really do not want to do a clean windows install and reinstall some 100’s of apps, many of which are real pains. Any and all help is deeply appreciated. I have spent the last 5 days trying to solve this myself, and realize this is way over my head. I can send new full CBS.log file if/when requested.
