Another way to bypass Windows 11 requirement checks (for a clean install)

spapakons · Apr 1, 2023

No, it won't make any difference on a compatible machine if you bypass compatibility check. Nothing else changes during the installation. The same components and features are installed, the same way. Just make sure you use an UEFI USB flash drive to use Secure Boot and other security features. If you install in Legacy mode, these features are not available. Think like a game looking for the original DVD before launching and you just bypass this check. Nothing else changes, the game is the same.

OK, Y'all. I made up my mind I'm finally going to attempt this on an old laptop. I think I've gotten answers to all the questions I asked except one regarding compatible machines.

#4. If I am clean installing windows on a compatible machine, do I need separate standard install iso media or is there any ramifications of using the same media as I've created for incompatible machines? (I'm taking the easy way out and use the Rufus method) I want to be able to bypass bitlocker device encryption on Home and use local account unless a user wants a MS account) Wouldn't subsequent version updates recognize that machine as being 100% compatible? Do I need separate install media depending on whether a machine is compatible or not?

Media created to bypass the system requirements can still be used on systems that meet the system requirements. All it does is skip the compatibility checks near the start f setup. Future upgrades will work fine in that instance.

Bottom line: Once you modify media to bypass the system requirement checks, you can use that same media on both system that meet and do not meet the Win 11 requirements with no penalties.

That is if the USB flash drive is created in UEFI (GPT) mode. If it is created in Legacy (MBR) mode, you have to bypass compatibility check to use it, even on compatible systems.

When booting from Windows installation media, Windows setup runs under Windows PE (Preinstallation Environment). This is contained within the BOOT.WIM file. All that is needed is to modify the Preinstallation Environment registry. Note that this will have NO effect on the final Windows installation - no registry changes or changes of any kind will be made to the final installation.

I might try this, just for fun!

Talk about trying to re-invent the wheel ......

what do you need adk for ? if you havent got cdimage you could use mkisofs, or just d/l oscdimg if you really want to rebuild an iso that way.

http://download.wsusoffline.net/mkisofs.exe

for a bit of variety there is no need to fiddle with the hives, could just pop these two text files into system32 of image 2 instead

winpeshl.ini

Code:

[LaunchApps]
SKIPALL.CMD
X:\SETUP.EXE

skipall.cmd

Code:

@echo off
echo adding reg entries to skip compatibility checks
reg add "HKLM\SYSTEM\Setup\LabConfig" /f /v "BypassTPMCheck" /t REG_DWORD /d 1
reg add "HKLM\SYSTEM\Setup\LabConfig" /f /v "BypassSecureBootCheck" /t REG_DWORD /d 1
reg add "HKLM\SYSTEM\Setup\LabConfig" /f /v "BypassRAMCheck" /t REG_DWORD /d 1
reg add "HKLM\SYSTEM\Setup\LabConfig" /f /v "BypassStorageCheck" /t REG_DWORD /d 1
reg add "HKLM\SYSTEM\Setup\LabConfig" /f /v "BypassCPUCheck" /t REG_DWORD /d 1
wpeinit
>nul TIMEOUT /T 3

for people who want to edit an iso simply and are happy using 3rd party tools , it can be done easily with anyburn free version,
so in that case there is no need for mkisofs or cdimage.

How to create ISO from Windows 11 22H2.22621.963 bootable USB Stick?

I've just started using Ventoy and would like to free up some of these Windows bootable USB pen drives I have and move their iso's over to a Ventoy USB pen drive. Since I no longer have the original ISO files for some of these releases. I'd like to reverse the process and turn the bootable USB...

If you want to modify some files from an ISO, you can use third-party tools such as MagicISO, UltraISO etc. Extract the file to be modified, make your changes and then import it back replacing the original.
