About Page Defrag, it appeared that Windows 2000 accepted the pagefile when Page Defrag was done defragmenting then when at the login screen, used the shutdown menu to reboot Windows 2000. If I log in right after it was done defragmenting, then Windows 2000 will complain about the pagefile being corrupted and disable it! In short, if I don't reboot again before logging in, the error message saying that the pagefile is corrupted pops up and Windows 2000 disables the pagefile.
