FYI, you are changing HKCU keys, the confusion is these keys are not named HKCU until the "Current User" is logged in. So mission accomplished, at least in theory.For future readers, if someone wanted to make the changes permanent, they could mount their WIM with DISM (to C:\Mount in my example), and modify the ntuser.dat offline. Just change the reg load command to point to the mount directory. reg load "HKU\DefaultUser" "c:\Mount\users\Default\ntuser.dat" Question: Anyone know of a program that can take a .REG file and convert it to reg.exe compatible script ? If I understand correctly you are looking to run a .reg file so you are not prompted to import the file into the registry and it runs silently. I do this by using winrar. I create a vbs script to silently run the reg file like below ----------------------------------------- dim WshShell Set WshShell = WScript.CreateObject("WScript.Shell") 'On Error Resume Next wShshell.Run "regedit /s yourregfilehere.reg" ------------------------------------------- I then package this script and the .reg file into winwar as an sfx and add the sfx commands below ;The comment below contains SFX script commands Setup=whatevername.vbs TempMode Silent=1 Overwrite=1 The resulting sfx winwar pakage will be saved as an .exe and can be pushed out to run the reg file silently. I can attach an example if I havent misunderstood your question ~G
