WOW
I just downloaded the PatchPae2.zip,but these instructions for its use look very complicated!
1. Download the PatchPae2 command line tool and extract the zip file to a
folder of your choice. For our example, we’re extracting to the root of
the C drive.
2. Open a Command prompt with Administrator privileges by pressing the Win
key, typing cmd into the search box and then simultaneously pressing Ctrl
+Shift+Enter. Then type the following:
cd C:\Windows\system32
3. Now, Windows Vista and 7 users type:
C:\PatchPae2.exe -type kernel -o ntkrnlpx.exe ntkrnlpa.exe
Windows 8 users type:
C:\PatchPae2.exe -type kernel -o ntoskrnx.exe ntoskrnl.exe
This makes a copy of and then patches the Windows kernel file to enable
the extra memory of 4GB and above.
4. Type the following to make a copy of and disable signature verification
in the Windows loader file:
C:\PatchPae2.exe -type loader -o winloadp.exe winload.exe
5. Enter this to create an entry in the Window boot menu, you can change
the text in quotes to what you want:
bcdedit /copy {current} /d "Windows Vista/7/8 (Patched)"
patchpae2 bcdedit
This should give you a “successfully copied to…” message with a number of
BCDID characters returned in brackets, make a note of them as you will
need to enter them in the following commands.
6. Enter the following commands in turn, pressing enter after each.
Replace BCD_ID with the ID you got from step 5:
bcdedit /set {BCD_ID} kernel ntkrnlpx.exe (for Win 8 use ntoskrnx.exe)
bcdedit /set {BCD_ID} path \Windows\system32\winloadp.exe
bcdedit /set {BCD_ID} nointegritychecks 1
Now reboot your computer and you should get a new entry on the Windows
Boot Manager to run the patched operating system.
Windows Boot Manager Patched menu
The good thing here is if you have problems, you can simply switch to the
unpatched normal system by rebooting because the kernel files were copied
and not overwritten. When you boot the patched system, a quick check
should show that your amount of memory is now fully utilized. Do note that
you still might not get access to all memory if some of it’s shared with
the video adapter, e.g. 512MB onboard graphics.
task manager 6GB ram
As you can see from the image above, we now have a 32-bit Windows 7
showing there is 6GB of installed RAM available.
resource monitor 6GB ram
This next image shows that Windows Resource Monitor confirms there is 6GB
of memory installed and ready to be used, with over 5GB still available
for use.
If you want to uninstall this patch again from your system, simply boot
into the unpatched Windows, press the Win key, type msconfig and press
enter. Then select the boot tab and highlight the patched boot entry,
click Delete. This screen can also be used for reducing the timeout and
selecting the patched install as the default o/s to boot into if you plan
on keeping it permanently.
delete boot menu
Also optionally go into C:\Windows\System32 and delete the ntkrnlpx.exe
and winloadp.exe files. If after a Windows update you find the patch no
longer works, re-run the command from step 3 to patch the kernel file
again.
