Consider two people using remote desktop to log into a server. On that server, define what you mean by "currently logged in user", there are two distinct ones.

maybe a stupid question but; why? If you need to store something as a service you can always use the HKLM. if you need the HKCU you'll kindly need to ask the user for a token so you can impersonate him (see ImpersonateLoggedOnUser) but when you are doing that you might as well have a process running in the users space that can access the HKCU....

HKEY_CURRENT_USER is a link to one of the entries under HKEY_USERS and is set in the user registry space at logon. I am not sure that that link is available to a service running under a different account. A simple piece of additional code in your service program should soon be able to tell you.

Since multiple users may have logged on ,use WTSEnumerateSessions to get a list of all the sessions and exclude session 0 from it.Next,use WTSQueryUserToken to obtain the user's sid and format it into a string by ConvertSidToStringSid.
You should get something like S-1-5-21-3853930826-1272693629-3426184057-501.Appending it to HKEY_USERS\ and you will get the key name you want.
