2000 professional Home and Pro Version ?????
Windows 2000 comes in few flavor:
Professional, Server, Advance Server, Advance server Data Base Center, there is no such thing as Home version.
Windows 2000 Professional was more geared toward corporate users but it works great as a stand alone Home desktop operating system,,,, you are right about system restore, it does not exist in Windows 2000 but you know what, Windows 2000 with SP4 does not need the restore option as much as Windows XP does....if you learn how not to abuse it, it will work just fine.
