I'm running WinXP, 32 bit. I'm the only user. I never set a password for being the "administrator" but I understand the default is that the first person who logs on to a new copy of XP de facto becomes the administrator and I am listed as that in Control Panel c. no pwd. because I never set one. It's never been a problem but recently I tried to install a new program and it asked for the administrator's password which, of course, doesn't exist. It seems to me that the simple thing to do is just create a password as I should have done in the first place. My question is: Am I risking anything if I just do that at this late date on a computer that is 5+ years old now? Thanks in advance for any help. DocBill
