Bypass Windows 11 Upgrade Assistant / Setup Hardware Checks (TPM, CPU, RAM)

This PowerShell script allows you to bypass TPM 2.0, unsupported CPU, and memory checks enforced by the Windows 11 Upgrade Assistant and setup.exe from Windows installation media. It eliminates common upgrade blocks such as:

• This PC doesn't currently meet Windows 11 system requirements.
• TPM 2.0 must be supported and enabled on this PC.
• The processor isn't currently supported for Windows 11.

What It Does

This script:

• Deletes legacy upgrade failure registry keys that may block future attempts.
• Simulates hardware compatibility by setting known override values (e.g., TPM, RAM, Secure Boot).
• Enables Microsoft's official upgrade bypass by setting AllowUpgradesWithUnsupportedTPMOrCPU to 1.
• Enables Upgrade Assistant to proceed by setting UpgradeEligibility to 1 under the current user.

Registry Keys Modified or Removed

Purpose	Registry Path	Action / Value
Clear upgrade failure flags	HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\CompatMarkers	Deleted (if exists)
	HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Shared	Deleted (if exists)
	HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\TargetVersionUpgradeExperienceIndicators	Deleted (if exists)
Simulate compatibility	HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\HwReqChk	HwReqChkVars = MultiString (TPM, RAM, etc.)
Bypass TPM/CPU check	HKLM\SYSTEM\Setup\MoSetup	AllowUpgradesWithUnsupportedTPMOrCPU = 1
Enable Upgrade Assistant flow	HKCU\Software\Microsoft\PCHC	UpgradeEligibility = 1

How to Use

Option 1: Save and Execute Locally

1. Save the script as: Windows11-Enable-Upgrade.ps1

2. Open PowerShell as Administrator.

3. Run the script:

.\Windows11-Enable-Upgrade.ps1

Option 2: Run Directly from the Web

1. Click the "Raw" button at the top right of the script to view it as plain text.

2. Copy the full Raw URL from your browser’s address bar.

3. In Administrator PowerShell, run:

irm "<paste raw url here>" | iex

✅ This lets you execute the script immediately without saving it to disk.

Windows11-Enable-Upgrade.ps1

<#
.SYNOPSIS
Bypasses Windows 11 hardware requirements for in-place upgrades.

.DESCRIPTION
This script modifies specific registry values to override system compatibility checks performed during
Windows 11 upgrades. It removes legacy upgrade failure entries, simulates compatible hardware state,
enables Microsoft's documented bypass policy for unsupported TPM or CPU configurations, and sets the
UpgradeEligibility flag required by the Windows 11 Upgrade Assistant.

This is intended for lab, evaluation, or controlled environments where hardware policy allows.

This allowed it to work for me specifically.

I've tried that file from the link you gave, it says its downloading but doesn't install Windows 11 in the end ?

I'm back it again, I've tried all the files, downloads OK but doesn't kick in and install, just goes straight back to the Windows 10 desktop

Hey @tommysmeg - Those just disable the TPM / Upgrade checks - the rest of the install is normal.

I just did a couple desktops by running those and then using the upgrade assistant.
https://www.microsoft.com/en-us/software-download/windows11

If you want to do a fresh install from disk, download a Windows 11 ISO and "burn" it to a USB w/ Rufus
https://rufus.ie/en/
There's a popup option to disable the checks built into this tool.

Doesn't seem to work on the latest version of Win 10 pro, I have a full blooded OS of Win10 Pro and dont want to loose any apps or data, I have tried rufus works well but Win 11 still remove all installed apps.

I have read that the Win 11 upgrade assistant doesn't remove your apps or data ( dont know how true that is ), I tried those bat files and reg files and it still says I need secure boot, so I edited the reg files needed added a few in to bypass those issues and it still comes up I need secure boot.

Win 11 upgrade assistant doesn't remove your apps or data:

It's pretty true actually.

I did it on a domain joined system remotely lol. Nothing at all lost, not even remote access.

I don't think it's related to the version of Win 10 tbh.

It's possible your system is booting in an older way (non-UEFI) - not really sure.

I'd take a complete backup (either way) and wipe it 😎

Yer I tired the upgrade assistant and kept getting I need secure boot even thou I disabled those steps, I can boot both ways UEFI and non UEFI
anyway I put it down to it can't be done on these machines so I'm going to give PCTrans ago, just putting the image onto the 2nd machine now so I can try it.

Secure boot needs UEFI, but you shouldn't be able to boot either way (UEFI or BIOS), only one way. If you can boot either way, Windows may have some boot remnants from a prior OS which may be part of the problem.

it's probably best to make a full backup then wipe it (remove partitions) and do a clean install. Then reinstall programs and pull in the files you need.

I managed to get it all going but I had to use Rufus

To bypass Windows 11 Upgrade Assistant checks, modify two registry values: set UpgradeEligibility to 1 in HKEY_CURRENT_USER\Software\Microsoft\PCHC, and AllowUpgradesWithUnsupportedTPMOrCPU to 1 in HKEY_LOCAL_MACHINE\SYSTEM\Setup\MoSetup. After running the registry file, you can upgrade without hardware checks using the Upgrade Assistant.

Thanks @PhoebeBaxter , worked with your suggestion. I was able to upgrade using Windows 11 Installation Assistant.

super helpful thank you!

Comigo não rolou.
PC ta com Windows 10 Pro em um dominio;
Tem todos os requisitos menos o TMP 2.0;
Fiz o processo de alterrar os registros, ele inicia a instalação pelo assistente de instalação, mas quando chega em 70% - 77% da 3° etapa,
ele buga e "começa do 0" e depois da erro. falando que o PC não tem o TPM 2.0. Tristeza

Translation from Portuguese to English:
Didn't work for me.
The PC is running Windows 10 Pro on a domain;
It meets all the requirements except for TPM 2.0.
I went through the process of changing the registry settings — the installation assistant starts the upgrade, but when it gets to 70%–77% of the third stage,
it crashes and "starts over," then gives an error saying the PC doesn't have TPM 2.0. Sad.

---

English response:
If it crashes, that sounds more like a compatibility issue with the CPU or other hardware components. You might check to see how old the hardware is.

---

Translation from English to Portuguese:
Se ele travar, isso parece mais um problema de compatibilidade com o processador ou outros componentes de hardware. Vale a pena verificar a idade do hardware.

---

Its an i3 10° Gen, 16Gb 3200Mt, 240Gb SSD NVME on an ASUS motherboard, only things the pc dont have is TPM 2.0

Hrm, not sure. I've performed the process on several machines. You might try this link someone else posted:
https://github.com/AveYo/MediaCreationTool.bat/blob/main/bypass11/Skip_TPM_Check_on_Dynamic_Update.cmd

Just a tip, In the end I got it going, now I've done it so many time's it just works, download the 11 ISO and burn it to USB using Rufus depending on your Windows 10 version, been UK, US or English International ISO, then the upgrade will allow you to keep all your files and apps, just have to know what version of Windows 10 your using. open the win 11 USB you created run the win 11 exe file from the USB using Windows explorer and upgrade that way.

Thank you for the simple no BS fix.

Thanks @cool-delete. I've made some improvements on that script and switched from using a reg file to a PowerShell script.

Let me know what you all think of the changes. 😎
