How to test a program for compatibility with different operating systems and architectures?

Question

Software testing

Are there any services or software with which you can check the application for compatibility? Ideally - with different OS versions. That is, so that it can be done both under Windows 10 and under XP. Also interested in the possibility of checking the work under x86\x64.
It will not work for everyone you know. You need a budget option. It remains only to install a virtual machine or something like that?

Answer 1

Actually yes. Usually they do this now, deploy a virtual machine park and test in them. Very comfortably. Install once, make a copy of a clean system, and every time with a clean system. Moreover, if the customer has some specific environment, then it is very easy to deploy it in a virtual machine, up to forwarding the corresponding equipment there (but it is not always forwarded, alas).
