im still having troubles i can not for the life of me get it to work....
here what i do
well first this is where my atomic is found at
c:\atomicfe

then i open up new text document in that document i write the following  exactly
c: 
cd \ 
cd atomicfe 
atomic.exe 
save it so it says atomic.BAT

then i keep it in the same folder as atomicfe
and then put it in the windows folder

then open regedit
HKEY_CURRENT_USER\ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion \Winlogon 
Add or Edit the Key : Shell 
HKEY_CURRENT_USER\ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion \Winlogon 
Add or Edit the Key : Shell 
HKEY_CURRENT_USER\ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion \Winlogon 
And put Shell = Atomic.BAT
like this

save it exit restart and no luck, when it boots it does nothing just goes back into windows like nothing happend,am i doing som thing wrong?
