I downloaded and ran hvciscan_amd64.exe. It identified seven drivers that "failed with compliance failure mask 00000202."
ssudcdf.sys
mbtusbser.sys
ctaud2k.sys
PxHlpa64.sys
rzpmgrk.sys
tifsfilt.sys
timntr.sys
I found details on each (description, company, version, date created, size, and multiple directories) for each and .inf files for five. I was able to delete an older version for ctaud2k.sys, but trying to delete any others said "File Access Denied: You require permission from SYSTEM to make changes to this file." I'm very reluctant to try removing the drivers or any .inf files since some are for Creative, Razer, and Acronis, all of which I use (I keep them all up-to-date). I don't recognize the names or companies for several, but that doesn't mean they aren't in use behind the scenes.
It seems strange, but after I deleted the older ctaud2k.sys, I tried rerunning hvciscan_amd64.exe (as an admin using PowerShell or Cmd) again and got the message "This app can't run on your PC. To find a version for your PC, check with the software publisher." After I rebooted, it worked and gave me the same results.
As suggested by Rodrigo.Queiroz, I also ran Disk Cleanup (Start menu, select Run as administrator) and deselected all options except "Device driver packages." It didn't seem to make any difference in the upgrade, but after rebooting, I haven't encountered any problems as a result.
