Maybe until #13 is merged, we can add a section to help people wanting to update windows version (that should avoid some issues)

We can add something like that:

### Update Windows version (from 1909 to whatever you want)
Open regedit program from your wine drive
`C:/windows/regedit.exe`

Then look for `HKEY_LOCAL_MACHINE/Software/Microsoft/Windows NT/CurrentVersion` and replace `CurrentBuild` and `CurrentBuildNumbere` by `whatever version you want`

Also we can add a link to releases with a bit of text to fix issues like #55 or #65
