Windows 8 CPU Feature Patch (Bypass Windows 8 CPU feature checks)

Already did all of this.
I'd like to receive answer from the guy who made this software.

 

I'm getting this 0x000000A error too when I try to boot normaly! I have a Dell M60 Notebook with Pentium M (no NX but SSE2, no PAE) and I did the PAE patch and "Remove winload patchguard x86" (winload.exe).. NoIntegrityChecks is set yes.. Please help

 

Patch on existing Windows 8.1 Installation?

Hello community,
has anyone ever tried to apply the patch for an existing installation of Windows 8.1?

Background:
I have a 64bit Windows 8.1 installation as a template (Image-File) with many Applications and want to distribute it on the PCs on my network.
The image runs without problems on newer PCs.
The image does not run on older PCs, it probably lacks a CPU feature (CompareExchange128).

Can I use the tool in this situation?

Thank you!

 

Are you sure Tito?
Aren't we already on 1.5?

Patches have been updated recently....

Cheers.

 

I already used V1.5.7. (downloaded yesterday).

Modifying the ntoskrnl.exe did not resolve the Problem.

Thanks!

 

Hi

I am currently running some tests on modified kernels, doing some debugging, and became curious how you solved it in your tool. Nice tool by the way. Point is I can't get it to work as I end in 0xc0000221. I've tried with and without renamed winload.exe/ntoskrnl.exe (as specified by PATH and KERNEL), but still the same. My initial tests are on Windows 8.1 x86 (6.3.9600), putting x64 on hold for the moment. Is the tool even supposed to work on this version of Windows? Or maybe I am doing something wrong.

On a side note I could add that I am able to solve it by patching 2 more instructions in winload.exe. It is 2 "js" instructions at:

Code:

OslpLoadAllModules+0x2D0 (4062ED)
OslpLoadAllModules+0x2E8 (406305)

 

Just adding another few cents to the thread. If you want to get rid of the requirement of NOINTEGRITYCHECKS in BCD store, you can patch these locations as well:

winload.exe

Code:

435740
435746
43574F

bootmgr.exe

Code:

40DB03 or 40DB0E
41A980
41A986
41A98F

Still on the same version as described in previous post.

 

I might have an easier way to change drive letters. Why not just use DISKPART [Enter]
LIST VOLUME
find the the volume ### you want to change the drive letter
then type
SELECT VOLUME [4] (or what ever drive you want to change the letter of)
then type
ASSIGN LETTER=Z (or what ever letter you want to assign the drive to)

I know for myself, navigating through the
"Control Panel\All Control Panel Items\Administrative Tools\Computer Management\Disk Management"

I know, I'm lazy. I'm better at typing than going threw menus. This is for Windows 7 Ultimate SP1 [32-bit].

If I missed the subject matter, I will apologize for my interruption.

Correct me if I'm wrong, as I was reading this thread, it seems now it's possible to install Windows 8 or Windows 8.1 on a Pentium 4 without NX but SSE2, no PAE? If is possible to install Windows 8/8.1 how could I do a fresh install of Windows 8/8.1? This is my CPU info Socket 478 for Intel(R) Pentium(R) 4 (Northwood) 3.00GHz and here is the Coreinfo.exe output (part of Sysinternals Suite):

I would really like to install Windows 8/8.1. I've been waiting for this "fix", "patch" for some time now. Everytime I attempt to install Windows 8/8.1 I receive the same ERROR 0xc0000221. Any assistance on this matter would really be appreciated.
Thank you.

 

I'm using 1.5 now it still says "patch location not found".
Since it looks like that the changed files are winload.exe, ntoskrnl.exe & hal.dll can you post the binary changes you made.
Thanks

 

How to use patch

Dear all,

I am a little bit lost . I have a pentium 4 and i followed Jan1 manual but at the end I miss something.
When I open the tools V.1.5 I want to remove pae check but i do not know how to apply the patch.
It opens windows Explorer and I do not know the next step
the same for remove sse2 eco,
pleas help .i need somo more sleep....

 

Succesfully installed windows 8.1 Enterprise 32bits on P4 2.8gb HT system with 2gigs of ram.
Everything went good except command, after booting to w8.1,

Code:

bcdedit /set {current} RecoveryEnabled No

administrator command prompt on w8.1 said that was an invalid-unknown command.

Searched for something like that on command info, without succes.
Then updates downloaded en after instalation system falls to recovery and then error.
Reapplied the patch with succes, succesfully runed

Code:

bcdedit /set {default} NoIntegrityChecks Yes 

but on reboot falls again to recovery and error.

Command

Code:

bcdedit /set {current} RecoveryEnabled No

booting from windows 7 disk also is not working.

It seems to me that the problem is to disable the recovery mode, but how?
Anybody has a clue? or am i doing something wrong?

Edit:
I did the whole installation again, i created 350mb system partition
and direct after first booting to w8.1 i elevated a prompt command
with shift plus f10 buttoms, gave the command bcdedit /set {current} RecoveryEnabled No
and it seems succeded disable the recovery mode.

Now i download again updates, lets see what will happen after patching again the files...
Continuing....

Edit 2:

YES, applying the patches after windows updates, and after several errors using the patch,
succeded to boot again. System is uptodated and activated together with office 2013,
runs smooth and stable. Seems to me smother then on windows 7.

All credits to Jan1 who made all these possible...

 

Great work on the patch, and they say it needs it. (lol, just trying to make people buy newer hardware they not need and what not.)
I'm going to try this what on my 2007 PC, using a P4 3.8Ghz, 3Gb RAM and see if it works well on 64-bit as I can do 32 np. (I think as it say it does have all but the other two that's only in 64-bit)

Edit:
Only used two patch for 8.1 Pro and worked great. I'm also updated, it funny how the 32bit and 64bit are not the same. (Not Bit part)

 

hi falkee

tried this as per your instructions using windows 7, it worked like a charm.

now using windows 8 9200 rtm with a p4 2.66 and 2gb of memory.

good instructions, well done and thanks.

With P4 3.8ghz and 3gb ram, 32bits w8.1 sould be running smooth like butter.
My old p4 2.8, with at the moment 2.5gb ram and clean w8.1 instalation,
seems to run better then a recent w8 friends laptop with all that preinstalled crap...

 

Hi!

First, i whant to thanks to Jan1 to make this great tool. Also thanks to all the community to share your



knowledge to make this possible.

I successfully installed Windows 8.1 Pro VL on my Pentium 4 2.8Ghz (no NX) - 1GB RAM - NVidia FX5200
and works like a charm! (i used windows vista/7 drivers without problems)

One more time, THANKS!

 

Hi guys!
Does any one made any iso of windows 8.1 x86 ready for installation on old computers and upload it?
