Microsoft never sold MSDOS 7 separately. But when upgrading from Windows 98 to Windows 2000, you'll end up with a hidden MSDOS 7 on your hard drive.

That leaves me with 4 questions:
What is it all about?
Where does it come from?
What happens, when upgrading from Windows Me?
And why is it there in the Windows 2000 final release, but only functional in the Windows 2000 Release Candidate 2?
