Hi,

I'm trying to get paths (CSIDL_MYDOCUMENTS, CSIDL_DESKTOP and 
CSIDL_PROFILE) for all the interactive users from a service application 
running in the LocalSystem account.

SHGetFolderPath() takes a hToken parameter, which "can be used to 
represent a particular user". Is there another solution than calling 
LogonUser() to generate this token ? To call LogonUser(), knowing the 
user password is compulsory, and I want to avoid to store any password 
in my application.

I know how to enumerate the users, but I don't see exactly how I could 
fetch the paths I need without knowing each user's password.

Any hint appreciated !

Regards,

A.R.

Because the service runs in a separate user acccount, it has to load the 
Registry hive for another user before it can query values from its 
HKEY_CURRENT_USER key.  Use LoadUserProfile(), ImpersonateLoggedOnUser(), 
and RegOpenCurrentUser() for that.

If a particular user is already logged in, you can enumerate the running 
processes for that user and extract a token from one of them that you can 
then duplicate and impersonate as needed.  But for users that are not logged 
in, you have to use LogonUser().
