Something like this

Uses
Registry;

procedure TForm1.Button1Click(Sender: TObject);
var
reg:tregistry;
begin
reg:=Tregistry.Create;
try
reg.RootKey:=HKEY_LOCAL_MACHINE;
reg.OpenKey('\SOFTWARE\Microsoft\Windows\CurrentVersion\',false);
if reg.ValueExists('Some_Value') then begin
if reg.ReadString ('Some_Value')='1' then Button1.Caption:='Yes';
if reg.ReadString ('Some_Value')='0' then Button1.Caption:='No';
end;
finally
reg.Free;
end;

This works fine for strings but does not seem to work for DWORD.

Sorry typo polices instead of policies and I should use integer for DWord

procedure TForm1.Button1Click(Sender: TObject);
var
reg:tregistry;
begin
reg:=Tregistry.Create;
try
reg.RootKey:=HKEY_LOCAL_MACHINE;
reg.OpenKey('\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\system\',false);
if reg.ValueExists('EnableLUA') then begin
if reg.ReadInteger ('EnableLUA')=1 then Button1.Caption:='Yes';
if reg.ReadInteger ('EnableLUA')=0 then Button1.Caption:='No';
end;
finally
reg.Free;
end;
end;

You are more than welcome to ask, add

reg.WriteInteger('EnableLUA',0);

to the code

procedure TForm1.Button1Click(Sender: TObject);
var
reg:tregistry;
begin
reg:=Tregistry.Create;
try
reg.RootKey:=HKEY_LOCAL_MACHINE;
reg.OpenKey('\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\system\',false);
if reg.ValueExists('EnableLUA') then begin
reg.WriteInteger('EnableLUA',0);
if reg.ReadInteger ('EnableLUA')=1 then Button1.Caption:='Yes';
if reg.ReadInteger ('EnableLUA')=0 then Button1.Caption:='No';
end;
finally
reg.Free;
end;
end;

Regards,
B.
