Hello, i used to replace the explorer.exe from the registrykey "winlogon" with my own startup .EXE . This worked like a charm for Win XP and later on for Win 7 (had to deactivate UAC for it to work on Win7). Now on Windows 10 i cannot get it to work at all. As usual i replaced the regkey "winlogon" with my own shell and i also deactivated the UAC. I also tried to link the "winlogon" to a shortcut that will start my .EXE with adminrights but still it does not work. After the initial boot up the screen just stays black...it does not start my .EXE . Sorry for my bad englisch but i hope it´s possible to understand what i am trying to do achieve here. Thanks in advance.
