Windows version upgrades (not monthly updates) move Duplicati from SYSTEM profile to `Windows.old`, which isn’t great (especially if you don’t notice before Windows removes that folder). For a service, safer places for Duplicati config use [Duplicati.Server.exe](https://duplicati.readthedocs.io/en/latest/07-other-command-line-utilities/#duplicatiserverexe) options `--portable-mode` or `--server-datafolder` which you can add by editing the service in Windows, or pass as [Duplicati.WindowsService.exe](https://duplicati.readthedocs.io/en/latest/07-other-command-line-utilities/#duplicatiwindowsserviceexe) options.

This is odd though, although details are scarce. If it was a Windows wipeout, you’d lose the configuration.

[Downgrading / reverting to a lower version](https://forum.duplicati.com/t/downgrading-reverting-to-a-lower-version/3393) talks about locations. It sounds like your service is likely using `C:\ProgramData\Duplicati`, but if you start Duplicati as you logged in, that’s the one in the user profile.

[Sysinternals Process Explorer](https://docs.microsoft.com/en-us/sysinternals/downloads/process-explorer) shows what executable image a process is on if you mouse-hover over it.  
Task Manager can probably do this if you select an `Image path name` column. Duplicati processes often come in pairs, with the initial launch from Program Files, then child on whatever’s the latest update found.
