You need to repair your Windows installation first, sometimes after enough updates it just corrupts itself.

Ain't that the truth. My older desktop's DHCP and WLAN services no longer work. So either I reinstall Windows 10 or see if I can get what I need it to do on Windows

Not sure if you're referring here to Windows or Microsoft as a company. Could fit either /S

Something that might work is downloading the current ISO, then mount it and run the setup
