C++/CLI and C# winform test in different OS

​Hi, I have some problems about C++/CLI and C# winform at .Net framework.

How to test my program in different OS.

The OS just like winXP、win7、win8.1、win10.

I build my program finish and test it in my computer, that had no problem.

My step is

1. Build and test in IDE.

2. Create a installer by "Visual Studio Installer - Setup Project".

But other people install in their computer had some problems.

(Not about .Net Framework version and VC++ runtime package)

I had test in clear win10 in virtual Box, but i had no other OS to test...

I have MSDN subscription (Visual studio subscription). So, I want to know how can i to test in different OS.

My apologies for the pool English.

Thank everyone for answers.
