Which Operating System occupies more Hard Disk Space?
I am currently having Windows98 and I want it to upgrade it. I have 15GB Hard Disk space and 128MB of RAM.
My question is can I upgrade it to Windows XP or WindowsNT or Windows 2000.
Which one will eat LESS HardDisk Space. Is it WindowsXP,NT or 2000?

Please let me know. Any help in this regard would be appreciated.

Thank you.
