When Windows 10 uninstalls/wipes an installed application from the OS, is there an event generated in the Application or any other event log, that would allow support to know this is why the app is gone?
I had a client who had installed and used a 3rd party industry specific financial application only to find it disappeared after a restart.
I figured out:
Windows 10 was at V1904 on this machine
It had tried to install 20H2 and failed some months ago
Because the user was unaware this process had failed, Windows sat in an inconsistent state
They installed an update to the Financial package which worked ok and ran without issue,
When they rebooted the computer for a separate reason, Windows rolled back the update process
as part of the roll back the installed Financial package was removed too (guessing due to Windows 10 rolling back to a system restore)
Does this also sound correct?
