Func _CheckIdleTime()

       ProcessWait("cmd.exe")
       Local $hwnd = WinGetHandle("[REGEXPTITLE:(?i)(.*cmd.*|.*cmd.*)]")

    EndIf
EndFunc   ;==>_CheckIdleTime

Func _Quit()
    Exit
EndFunc   ;==>_Quit

The first attempt !!!, to control the power plan through idle. This script should adjust the power plan to the individual situation. This is to slow down the overheat. 

findTemp() function will only run on supported systems!

This batch script shows you whether your system support this function:

If the script does not work,  meaningless values are outputted.

@echo off
for /f "delims== tokens=2" %%a in (
    'wmic /namespace:\\root\wmi PATH MSAcpi_ThermalZoneTemperature get CurrentTemperature /value'
) do (
    set /a degrees_celsius=%%a / 10 - 273
)
echo %degrees_celsius%
pause

      With _WinWaitActivate we can wait for a window to process it.
      But is there any logic so that we can wait for this window title and based on the window text (like 2 or more patterns will be there) we can click yes or no on the window.
       
      Func _WinWaitActivate($title,$text,$timeout=0)
       WinWait($title,$text,$timeout)
       If Not WinActive($title,$text) Then WinActivate($title,$text)
       WinWaitActive($title,$text,$timeout)
      EndFunc

      Whenever we try to access a network share it will prompt for credentials based on the shared folder settings.
      Like the below prompt


      Once you save them, they are saved in Windows Credentials of Credentials Manager in Control panel (run --> control keymgr.dll).

       
      But not able to found exact file or registry for this setting.
       
      So, can anyone suggest how to do this process of adding network credentials using AutoIT.
