Ok howbout this...
if you open up "My Computer" and goto:
%SYSTEMDRIVE%\Documents and Settings\
(%SYSTEMDRIVE% = the drive that windows is installed on)
this is where all the user funk is normally stored on the drive. In that directory you should find:
Administrator (for the administrator user)
All Users (For stuff that is common to all users)
Default User (Default stuffs new users will get when they are created)
and a directory for each user you have on the system.
Using Regedit:
The reg paths in the previous post tell windows where all the funk like "My Documents", "Favorites" and whatnot will be found.
HKEY_CURRENT_USER refers to the user that is currently loged in and is relative the logged in user (What Joe would see here when loged in would be different from what Jane would see), these can be unique to the user.
HKEY_LOCAL_MACHINE is the system wide settings these are the defaults for system.
If the keys in the HKEY_CURRENT_USER hive point to the users directory under "Ducments and Settings" everyone will have seperate directorys for their junk. If they are set to something like "%ALLUSERSPROFILE%\whaterver" everyone would be sharing the same junk.
Lets take favorites for example..
using Regedit follow the path for HKEY_CURRENT_USER from the previous post. in that path you will se Favorites REG_SZ and the path that windows is using to store your "favorites" that SHOULD be pointing to <driveletter>\Documents and Settings\<YOU USERNAME HERE>\Favorites if not then you can click on the name of the key and change the path to wherever you want it to be located.
hmm that should be clear as mudd
