'wine cmd -c ver' ?
Thanks for the suggestion. It's semi-helpful, but doesn't distinguish in some cases: With wine-5.9-196-gc0cb9cbe95:
nt351 / Microsoft Windows 3.51.1057 nt40 / Microsoft Windows 4.0.1381 win95 / Microsoft Windows 4.0.67109814 win98 / Microsoft Windows 4.10.67766446 winme / Microsoft Windows 4.90.73010104 win2k / Microsoft Windows 5.0.2195 winxp / Microsoft Windows 5.1.2600 win2k3 / Microsoft Windows 5.2.3790 vista / Microsoft Windows 6.0.6002 win2k8 / Microsoft Windows 6.0.6002 win20 / Microsoft Windows 6.1.7601 win2k8r2 / Microsoft Windows 6.1.7601 win30 / Microsoft Windows 6.1.7601 win31 / Microsoft Windows 6.1.7601 win7 / Microsoft Windows 6.1.7601 win8 / Microsoft Windows 6.2.9200 win81 / Microsoft Windows 6.3.9600 win10 / Microsoft Windows 10.0.17134
so vista/win2kr8 are the same and win20/win2k8r2/win30/win31/win7 are the same.
