why when i run the loop function Check_Windows_Turned_OFF ,installer stop work and auto closed??

!include "x64.nsh"
!include "WndSubclass.nsh"
!include "WinMessages.nsh"

Function Check_Windows_Turned_OFF_Action
  ${If} $2 = ${WM_QUERYENDSESSION}
	WriteRegStr HKLM "SOFTWARE\1" "1" "OFF"
    Quit
  ${EndIf} 
FunctionEnd

Function Check_Windows_Turned_OFF
FindWindow $0 "#32770" "" $HWNDPARENT
${WndSubclass_Subclass} $0 Check_Windows_Turned_OFF_Action $5 $5
FunctionEnd

Section
BK:
Call Check_Windows_Turned_OFF
Goto BK
SectionEnd

That loop makes no sense. You can't call code in sections if you are subclassing.

What is the correct way to do this?
Should change all the codes?

I don't know if I make it right also, but if I want to avoid exit from the installer, I use the following code in the section:

; Dummy section
Section Dummy
ENDLESS_LOOP:
  Sleep 1000
  GoTo ENDLESS_LOOP
SectionEnd

Your function Check_Windows_Turned_OFF_Action should be called automatically on every message that is received from the dialog.
