vista caused this
I reeeaaalllyyy hope they are not still supporting Vista.
What makes people think that Vista is stuff is the changes Vista has. Vista no longer has DOS. It uses CMD and a different boot operation. And many programs and games were incompatible with Vista. But the OS overall is pretty good.
DOS was implemented in XP. Which is why you can run DOS programs that would otherwise give an error in Vista+
If you're right, DOS must be emulated.
