Disable PatchGuard & Driver Signing

[Fyyre]

Hi Gelip!

Did this work for you? If so -- wonderful! =)

I will note:

hFiref0x and I created UPGDSED based on my "disable PG/DS" idea and research.

I'm not sure if you tried using it... it should still work fine, although the project is no longer updated.

Perhaps someone released a more modern way to disable DSE and PatchGuard? However I am unfamiliar with what alternatives are.

Be well!

OK, I make second mk_bcdentry_UEFI.cmd script for UEFI:

ECHO OFF

ECHO.
ECHO Copy of required files...
ECHO.

set PATCHTEMP=%CD%
cd %PATCHTEMP%
echo y | copy %WINDIR%\SYSTEM32\winload.efi %PATCHTEMP%\osloader.efi
echo y | copy %WINDIR%\SYSTEM32\ntoskrnl.exe %PATCHTEMP%\ntkrnlmp.exe

set OLD_GUID={46595952-454E-4F50-4747-554944FFFFFF}
set ENTRY_GUID={46595952-454E-4F50-4747-554944FEEEEE}

ECHO.
ECHO Delete BCD Entries, if existing...
bcdedit -delete %ENTRY_GUID%
bcdedit -delete %OLD_GUID%
ECHO.

ECHO.
ECHO Creating BCD Entry...
ECHO.

bcdedit -create %ENTRY_GUID% -d "PatchGuard Disabled v3" -application OSLOADER
bcdedit -set %ENTRY_GUID% device partition=%SYSTEMDRIVE%
bcdedit -set %ENTRY_GUID% osdevice partition=%SYSTEMDRIVE%
bcdedit -set %ENTRY_GUID% systemroot \Windows
bcdedit -set %ENTRY_GUID% path \Windows\system32\osloader.efi
bcdedit -set %ENTRY_GUID% kernel ntkrnlmp.exe
bcdedit -set %ENTRY_GUID% recoveryenabled 0
bcdedit -set %ENTRY_GUID% nx OptIn
bcdedit -set %ENTRY_GUID% nointegritychecks 1
bcdedit -set %ENTRY_GUID% inherit {bootloadersettings}

bcdedit -displayorder %ENTRY_GUID% -addlast
bcdedit -timeout 10

ECHO.
ECHO Setting PEAUTH service to manual... (avoid BSOD at login screen)
ECHO.
sc config peauth start= demand

ECHO.
ECHO Calling patcher!  Please press "Patch", next "Exit" before continue here...
ECHO.
%PATCHTEMP%\no_ds_pg.exe
ECHO.
ECHO.

ECHO.
ECHO Copy of required files...
ECHO.
echo y | copy %PATCHTEMP%\osloader.efi %WINDIR%\SYSTEM32\osloader.efi
echo y | copy %PATCHTEMP%\ntkrnlmp.exe %WINDIR%\SYSTEM32\ntkrnlmp.exe
ECHO.

ECHO.
ECHO Process complete.  Upon reboot system and select "PatchGuard Disabled v3".
ECHO.

pause

You need select file osloader.efi to patch manually. Tested on Win7 SP1 17514

Yes, but Win7 must be activate or work only 30 day from fresh install OS. I test driver signing BeepXP:

Normal boot - digital signature error (service beepxp not running)

PatchGuard Disabled v3 - service beepxp running, driver works :

Do something Microsoft doesn't like such as modify the SSDT or Shadow SSDT. Better yet, I can send you some ancient source for a x64 process hider I made, that also does the trick.
