windows - Why can a double clicked batch file not find a registry value for deletion? -
i wrote bat file delete registry entry.
reg delete hkey_local_machine\software\microsoft\windows\currentversion\run /v value /f when execute in cmd, works.
but when execute double click, doesn't!!!
error message:
error: system not find specified registry keys or values anyone else can tell me why!
on 64-bit windows there automatic start of 64-bit applications
hkey_local_machine\software\microsoft\windows\currentversion\run
and automatic start of 32-bit applications
hkey_local_machine\software\wow6432node\microsoft\windows\currentversion\run
if batch file executed 32-bit cmd.exe in directory %systemroot%\system32\ being automatically redirected 32-bit applications %systemroot%\syswow64\, registry path
hkey_local_machine\software\microsoft\windows\currentversion\run
is automatically redirected to
hkey_local_machine\software\wow6432node\microsoft\windows\currentversion\run
if batch file executed 64-bit cmd.exe in directory %systemroot%\system32\, can called 32-bit applications on windows x64 using redirector %systemroot%\sysnative\ instead of %systemroot%\system32\, registry path
hkey_local_machine\software\microsoft\windows\currentversion\run
is indeed referencing
hkey_local_machine\software\microsoft\windows\currentversion\run
so suppose value exists in run key 32-bit applications (below wow6432node), batch file on double click executed 64-bit cmd.exe because 64-bit windows explorer used. therefore value cannot found in run key 64-bit applications.
the solution use
%systemroot%\sysnative\reg.exe delete hkey_local_machine\software\wow6432node\microsoft\windows\currentversion\run /v value /f please note special redirector %systemroot%\sysnative\ exists on 64-bit windows , 32-bit applications, not exist on 32-bit windows. take consideration if batch file should work 32-bit windows.
for more information redirections on windows x64 read msdn articles
