I run XP Professional on my computer and I'm the only person who uses
this computer. I have a small hard drive, so XP uses the FAT32 file
system. I can't encrypt files using FAT32 as can be done with the
NTFS file syatem so I don't have any password issues to deal with here
.... I do have a third party program that I use to encrypt files tho.
I've recently changed the Administrator's name to something else.

That's the background ... now for the question:

Is it safe for me to change the Administrator's (now named something
else) password? To do this I make my own account part of the
Administrator's Group and then try to change the Administrator's
password from my account. When I do this I get a warning that I may
make changes that are irreparable such as losing passwords, etc.
Is this safe to do? Can I change the Administrator's password on a
regular basis or is this something best left alone once set?

Thanks for any good advice.
