Wow64Enable And Wow64Disable Question about?

Recommended Posts

What do we need to use?
There is a lot of confusion about it, you can tell clearly and clearly ..
_WinAPI_Wow64EnableWow64FsRedirection(False) In terms of not having a mess in the operating system after doing so
_WinAPI_Wow64EnableWow64FsRedirection(True) Do we have to?


Or which of the following is the correct use?

#RequireAdmin
#include <WinaPIFiles.au3>

$CMD = 'Dism.exe /online /enable-feature /featurename:LegacyComponents'

If @OSVersion = "WIN_10" And @OSArch = "X64" Then
    DllCall("kernel32.dll", "boolean", "Wow64EnableWow64FsRedirection", "boolean", 0)
    DllCall("kernel32.dll", "int", "Wow64EnableWow64FsRedirection", "int", 1)
    _Wow64FsRedirection(False)
    _WinAPI_Wow64EnableWow64FsRedirection(False)
    RunWait('"' & @ComSpec & '" /k ' & $CMD, '', @SW_SHOW)
    _WinAPI_Wow64EnableWow64FsRedirection(True)
    _Wow64FsRedirection(True)
    DllCall("kernel32.dll", "int", "Wow64DisableWow64FsRedirection", "int", 1)
    DllCall("kernel32.dll", "boolean", "Wow64EnableWow64FsRedirection", "boolean", 1)
EndIf

Func _Wow64FsRedirection($state) ;alternativeWow64
    If Not @AutoItX64 And @OSArch = 'X64' Then
        If $state Then
            DllCall("kernel32.dll", "int", "Wow64RevertWow64FsRedirection", "int", 0)
        Else
            DllCall("kernel32.dll", "int", "Wow64DisableWow64FsRedirection", "int", 0)
        EndIf
        If @error Then Return SetError(1)
    EndIf
EndFunc   ;==>_Wow64FsRedirection

then that must be right use

#RequireAdmin
#include <WinaPIFiles.au3>

$CMD = 'Dism.exe /online /enable-feature /featurename:LegacyComponents'

If @OSVersion = "WIN_10" And @OSArch = "X64" Then
    _WinAPI_Wow64EnableWow64FsRedirection(False)
    RunWait('"' & @ComSpec & '" /k ' & $CMD, '', @SW_SHOW)
    _WinAPI_Wow64EnableWow64FsRedirection(True)
EndIf

On a 64 bit OS running a 32 bit process, redirection sets the system folder as SysWOW64. If you want to access the System32, you can use _WinAPI_Wow64EnableWow64FsRedirection (False) function.  Normally, you want to do that because the SysWOW64 DLL is missing or does not work properly.  So you should use it on very exceptional situations, not all the time...
