I have some software and I'd like to know if it works on the next version of Windows (Windows 10).
With Windows 10 you have 30 days where you can roll back. So you could upgrade and then test it, if it fails, roll it back.
You also have the option of virtual machines.
I don't recommend asking others if they have had success because their computer spec/environment is likely to be different which may cause different behaviours.
As per @BigChris comments
You've also got the "compatibility mode" options that attempt to help older software continue to run on newer OSes... ideally, though, the OP should be finding out from the software vendor if they have a new version for Windows 10...
