What software is that?

I have lots of programs developed in Quick Basic 4.5 and Visual Basic
3; lots of critical stuff I use often ...

e.g.(s) - converting numbers between different bases, calculating
times between dates, regression curve fittings ( linear, polynomial,
exponential and power models ), censored data analysis, Gauss-Jordan
elimination calculations, stereo imaging software, John Conway's game
of life, mortgage calculations, thermal endurance life testing
analysis, thermal degradation data analysis ( both conventional and
FTFM methods ), wire insulation thermal data analysis ( 3 models )

- to name a few that come to mind.

None will run in Windows 7, 8 or 10 !

16-bit software? If you are running a 64-bit Windows, 16-bit
software will not run.

So glad I have an XP virtual machine !

I use DOSBox myself for some 16-bit utilities that I wrote in
QBasic.
