changing back to win2000

[emily]

i have xp pro on some of my machines now. i have a dos
program that for whatever reason is having trouble running
on the computers with xp. there is no trouble on the win
2000 machines.

I gues my question is can i change to win 2000 without
having to format the drive. I really dont want to reload
all the other programs, etc...

thanks

The only way to return to Windows 2000 is to reformat your
drive and reinstall Windows 2000 "clean".

Have you tried using XP's Program Compatibility Wizard?

Open XP's "Help and Support" and type: OLDER PROGRAMS , and hit enter.

Greetings --

There is no "rollback" to Win2K.

If you want to replace WinXP with an earlier OS, you're certainly
entitled to do so, as long as you've purchased a legitimate copy of
that earlier OS. (Although I can't imagine why you'd want to.)

To replace WinXP with an earlier OS, you'll have to boot from the
appropriate boot disk, format the hard drive, and install. There is
no supported downgrade path or technique.

Simply boot from the Win2K installation CD. You'll be offered the
opportunity to delete, create, and/or format the system partition as
part of the installation process. (You may need to re-arrange the
order of boot devices in the PC's BIOS to boot from the CD.)
