Where to buy Windows 7 Software

[unfazed]

Anybody here heard of Virtual Machine.

You can use Windows version or Vmware who have a free desktop version

I run XP pro and Windows 7 as VMs in the windows 10 pro, to test old software for people who have had to buy new machines which are not down gradable.

Solves the backward compatibility issues of old software. You can even run old dos based programs this way.
