Updating The Registry

[sepehr]

i've posted this in couple of forums and searched alot but didn't comeup with much info

as u know for registry to take effects it needs windows to be restarted and
delphi offers some APIs that does sth and updates registry automatically like setting a wallpaper,but i can't get to update registry after creating a
"NoDrives" key in
Software\Microsoft\Windows\CurrentVersion\Policies\Explorer
then changing it to some values to hide it

now after all of this i can't update my registry without restarting and that's a BIG drawback for my program
