This is a FEATURE of running as a limited user rather than as the Admin.
No limitied rights account can pry into the contents of the system or another
LUA account -- no extra software required
- as ADMIN, add a New User account
- set that account as limited access
- log into the New User (which will create the directories)
Repeat 2-3 for an account for your snoopy brother.
(CAUTION: Quickbooks has a problem running from the above setup --
google LUA Quickbooks for insight on the issue).
Use the Admin account ONLY for system maintenance (MS UPDATES) and
run email/browsers from the New Account.
You can copy your existing files to the \Documents and Settings\
New User\ location while logged in as Admin.
Now change the Admin password and the New User Password.
