I'm pretty sure you're serious (not being sarcastic), so let me play straight for you... Of COURSE they dropped Virtual XP support in 10. The last thing in the world they want is any more instances of XP running anywhere.
I am serious. I’m not going to spend in excess of $100,000 to get a team together to write and debug all new programs to replace the ones I use to run my business. Win7 runs Virtual XP, so why not Win10?
