HKEY_CURRENT_USER under system account

[dh]

We have a 3rd party DLL which reads entries under HKEY_CURRENT_USER.

However, the DLL will be used under system account. My questions are:

1. System account has its own HKEY_CURRENT_USER though it is not shared with
other users?

2. If 1 is true, then what we can do is before loading the DLL, we have
another program runs under the system account too, which will write entries
into HKEY_CURRENT_USER under the system account. Then load the DLL. Will this
work?

3. Is there any better way around this, if 2 is a solution at all?

Thanks!

No better way to find out than to try. Check this out:

Yes, it's ".DEFAULT".

If the DLL loads unter the system account then
HKEY_CURRENT_USER points to ".DEFAULT".

Get the users access token (WTSQueryUserToken XP+ or steal
from explorer under W2K) and get user's HKEY_CURRENT_USER
by LoadUserProfile.
