Hello I just developed software on XP and later did check on win 7 and
just moment ago, the software failed on windows 10 64bit.
I'm webdeveloper and this is first time developing windows software,
so here comes the question:
Is there platform to test software on all versions of windows?
One option that I used for webdevelop, was virtualbox and
download the all versions of windows: https://developer.microsoft.com/en-us/microsoft-edge/tools/vms/
but it seems that it doesn't work for programs only for browsers
(from point I checked, maybe I'm wrong).
So are there windows versions that are full and free of charge
to download and test it in virtualbox?
Or I need to get all windows licences?
