var
reg:=tregistry;
begin
Reg:=TRegistry.Create;
Reg.RootKey:=HKEY_CURRENT_USER;
Reg.createKey('Software\Microsoft\Windows\CurrentVersion\Policies\System');
Reg.OpenKey('Software\Microsoft\Windows\CurrentVersion\Policies\System', true);
Reg.WriteString('(Default)','1');
end;

upon running the command, the value for '(Default)' remains at 'value not set'. i do not have a problem setting the values for other stuff except for the prime (Default) value for every key.

please help

I'm sure you have to rename the '(default)' value before you can assign data to it.

RenameValue(const OldName, NewName: String);

MadShi had the correct solution. I didn't test, I just posted what works for other portions of the key.

var
reg:tregistry;
begin
Reg:=TRegistry.Create;
Reg.RootKey:=HKEY_CURRENT_USER;
Reg.createKey('Software\Microsoft\Windows\CurrentVersion\Policies\System');
Reg.OpenKey('Software\Microsoft\Windows\CurrentVersion\Policies\System', true);
Reg.RenameValue('(Default)','Default');
Reg.WriteString('Default','1');
end;

creates a new value name

Default Reg_Sz 1

but you still have

(Default) REG_SZ (value not set)

Yes. Madshi's method works.
reg.WriteString('',1);
Did you test?
