User/SID doesn't appear in HKEY_USERS

Hi,

I'm looking to add a key to a the HKEY_USERS hive through the reg command but when I run it I get an "invalid parameter" error. When I got to the HKEY_USERS hive I don't see the SID concerned however when I go to HKEY_LOCAL_MACHINE > SOFTWARE > MICROSOFT > WINDOWS NT > CurrentVersion > Profile List I can see all the profiles and corresponding SIDS.

I'm not sure how this is supposed to work, what changes do I need to make to a user to have the SID populate in HKEY_USERS so that I can add the registry entries?

The user's hive is found here: c:\users\x\ntuser.dat

If it is not loaded, you can do it manually from the file menu > load hive

I'm aware this file exists in Windows XP but I've never been able to find it in Windows 7. So you think the hive exists but just isn't visible? I tried making changes on this profile such as mapping drives for the hive to appear but no joy so far!

The file is there. It is marked as a system and hidden file. To see it in explorer, both type of files must be enabled in folder options.

Sorry I missed the setting about viewing system files. I can see the NTUSER.DAT file now and open it in regedit but I don't think it's helping when I'm trying to run this script.

Here is what I'm trying to do, I've got a batch file that performs several registry modifications on the SID of a user account. I'm having to run the batch file to 'remotely' edit the users registry from an admin account due to system restrictions on the actual user. When I run it I get an error "invalid parameter", I can't see the SID under HKEY_USERS so I'm assuming that's why the command won't work; the key doesn't exist.

Is there a quick way for the system to create this SID entry in the registry? I thought mapping drives and printers would create personal information and so the SID would appear but no luck so far.

Here's an example of a command in the batch file:

reg.exe add "\\PCNAME\HKU\S-1-5-21-294320614-28697689200-2976616192-6280\SOFTWARE\Avaya\Supervisor\16.0\Automation" /f

Any ideas?
