restart explorer.exe

Hello,

I am changing the Desktop folder location in the registry and I would like to restart explorer.exe to apply changes.

Problem is: after explorer restart only the libraries open and desktop icons, task bar, clock etc are missing (see attached screenshot)

It works after restart, but I want to avoid a restart

 

#include <MsgBoxConstants.au3>

While ProcessExists ("explorer.exe")

    ProcessClose ("explorer.exe")

Wend

sleep(1000)

Run("explorer.exe")

sleep(1000)

If NOT ProcessExists("explorer.exe") Then Run("explorer.exe")
EnvUpdate()
MsgBox(0,"",@UserName)

Hi hendrikhe,

I would do it like so:

#include <WinAPI.au3>
#include <WinAPISys.au3>

;Save icon positions (probably not needed since we are doing a graceful exit ..)
DllCall("shell32.dll", "none", "SHChangeNotify", "long", 0x8000000, "uint", BitOR(0x0, 0x1000), "ptr", 0, "ptr", 0)

;Close the explorer shell gracefully
$hSysTray_Handle = _WinAPI_FindWindow('Shell_TrayWnd', '')
_SendMessage($hSysTray_Handle, 0x5B4, 0, 0)

While WinExists($hSysTray_Handle)
    Sleep(500)
WEnd

_start_explorer()

While Not _WinAPI_GetShellWindow()
    Sleep(500)
WEnd

EnvUpdate()

; continue script

Exit

Func _start_explorer()
    $strComputer = "localhost"
    $objWMI = ObjGet("winmgmts:\\" & $strComputer & "\root\CIMV2")
    Local $objexplorer = $objWMI.Get("win32_process")
    $objexplorer.create("explorer.exe")
EndFunc   ;==>_start_explorer

Try this one:

#include <WinAPIShellEx.au3>
#include <SendMessage.au3>

_Restart_Windows_Explorer()
ConsoleWrite("+ Result: " & @error & @crlf)

Func _Restart_Windows_Explorer()
    ; By KaFu

    ; Believed to save icon positions just before Shutting down explorer, which comes next
    _WinAPI_ShellChangeNotify($SHCNE_ASSOCCHANGED, 0, 0, 0)

    ;Shutting down explorer gracefully
    Local $hSysTray_Handle = DllCall("user32.dll", "HWND", "FindWindow", "str", "Shell_TrayWnd", "str", "")
    If Not IsHWnd($hSysTray_Handle[0]) Then Return SetError(1)

    Local $iPID_Old = WinGetProcess($hSysTray_Handle[0])

    _SendMessage($hSysTray_Handle[0], 0x5B4, 0, 0)

    #cs
        Local $i_Timer = TimerInit()
        While IsHWnd($hSysTray_Handle[0])
            Sleep(10)
            If TimerDiff($i_Timer) > 5000 Then Return SetError(2)
        WEnd
    #ce

    Local $i_Timer = TimerInit()
    While ProcessExists($iPID_Old)
        Sleep(10)
        If TimerDiff($i_Timer) > 5000 Then Return SetError(3)
    WEnd

    Sleep(500)

    Return ShellExecute(@WindowsDir & "\Explorer.exe")

EndFunc   ;==>_Restart_Windows_Explorer
