By default, service's run in the LocalSystem account, which allows them to
run outside of the context of any user login session.  However,
HKEY_CURRENT_USER is only accessible once a user actually logs in.  The only
way to gain access to HKCU from a service is to either:

1) manually log in a specific user account via LogonUser() function

2) detemine if the user is already currently logged in, grab its security
tokens, and adjust the tokens of your own calling thread to impersonate the
user.  Note that with the introduction of XP's "Fast User Switching"
feature, this may become even more complicated since multiple users can be
logged in at the same time now.

When no user is logged in yet, any access to HKCU is going to go to
HKEY_USERS\.DEFAULT since the current user's key has not been loaded yet.

The LocalSystem account has full access to the entire machine.  If, on the
other hand, you configured the service to run under a specific user account,
then the service is restricted to whatever the user account is restricted
to.
