Bug ID: 58209
           Summary: add an environmental variable to control the Windows
                    Version
           Product: Wine
           Version: 10.7
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

the current environmental variables only include:
https://gitlab.winehq.org/wine/wine/-/wikis/Wine-User%27s-Guide#environment-...

WINEDEBUG
WINEDLLOVERRIDES
WINEARCH
WINEPREFIX

there shoud also be an environmental variable to set the Windows Version
(currently set using `winecfg` and choosing Windows Version at the bottom of
the Applications tab)

usage:

WINEWINVER=winxp wine my-old-program.exe

all versions should have a corresponding WINEWINVER variable:
WINEWINVER=
 win11
 win10
 win8.1
 win8
 win2008r2
 ...etc...

This also helps speed up testing of apps with issues, it's much faster than
switching Windows Versions using `winecfg` and relaunching the app

You'll have to relaunch anyway, but you can use "winecfg /v winxp" from command
line already, to avoid going through UI.

Then you can configure different version reported for a given exe file you run,
if you need this change set permanently for some application.

Thank you, I was able to figure out the options
> Usage: winecfg [options]
>
> Options:
>   [no option] Launch the graphical version of this program.
>   /v          Display the current global Windows version.
>   /v version  Set global Windows version to 'version'.
>   /?          Display this information and exit.

> Valid versions for 'version':
>    win11  Windows 11
>    win10  Windows 10
>    win81  Windows 8.1
>     win8  Windows 8
>
> win2008r2  Windows 2008 R2
>         win7  Windows 7
>      win2008  Windows 2008
>        vista  Windows Vista
>      win2003  Windows 2003
>      winxp64  Windows XP 64
>        winxp  Windows XP
>        win2k  Windows 2000
>        winme  Windows ME
>        win98  Windows 98
>        win95  Windows 95
>         nt40  Windows NT 4.0
>        nt351  Windows NT 3.51
>        win31  Windows 3.1
>        win30  Windows 3.0
>        win20  Windows 2.0

So I could launch an app with:
winecfg /v winxp && wine my-old-program.exe
