[Bug 41269] MSI uninstaller does not clean up Registry's UpgradeCode, ProductCode

https://bugs.winehq.org/show_bug.cgi?id=41269

--- Comment #42 from Reinhold  ---
No I have not aware of such a function in Windows.

The inconsistany in the Registry with Wine comes from this bug.
- even when this bug is corrected an existing Wine Registry stays inconsistant
- only a new Wine setup AND with new installations of all those MSI apps the
Registry becomes clean ( and, of course, for a a new WINEPREFIX)

In order to get a clean Registry with an existing Wine installation when
updating the corretion, does Wine need to be newly installed AND all apps? 
My view: cannot be the solution.

Alternatively, at the Wine installation with the corrections a somehow "audit"
function needs to be added to clean the Registry inconsistancy.

I think an answer needs to be provided with the correction. Or if Wine offers
such capabilities, please let me know.
