I've got a copy of the fairly rare/dismal racing game Kraze, by 7Seas/Candella. It was working on Win10 fine last year, but now boots up and does nothing (not even the pre-launch splash screen).
I ran it through Process Monitor and it seems to get so far then just stops.
I don't know if the issue is caused by updated graphics drivers, or, more likely, updated Win10 files.
If you're someone good at analysing these sort of things, send me a PM.
