Loading Default User hive (ntuser.dat)

Loading Default User hive (ntuser.dat)
From some of the testing I have done, I am finding that some registry keys do not work correctly if they are just created under HKU\.default.

I have found that if I load the ntuser.dat file (C:\Documents and Settings\Default User\ntuser.dat) into regedit and make the necessary changes, then they will work correctly when a new user logs in.

I can script this using reg load, add, and unload. I was wondering if there was a better way to get that done with just using NSIS and not needing reg.exe on the existing pc (Windows 2000).

Any assistance would be appreciated.

Thanks,
DF
