How to Bypass TPM for Windows 11 Installation (Nov 2025)

When installing Windows 11, you may encounter issues due to TPM 2.0 or Secure Boot requirements.
Here’s a simple method to bypass verification by modifying the registry.
Confirmed working as of November 2025.
Works well with Win11_25H2.iso.

What is TPM?

Still, to understand what this is, here’s some basic information.

TPM (Trusted Platform Module) is a security chip installed on the computer’s motherboard.
It securely stores encryption keys and verifies system integrity.

The TPM 2.0 standard itself was introduced in 2015,
and Microsoft mandated manufacturers to include TPM 2.0 as standard on all new PCs starting July 2016.

While TPM could be used in Windows 10, it was not mandatory.
However, five years after mandating manufacturers, Microsoft made TPM 2.0 a mandatory requirement starting with Windows 11 in 2021.
As information security grows increasingly important, security is being strengthened at the PC hardware level as well.

The problem is that many PCs released before 2016, before this policy was established, do not have TPM 2.0 ready.

Nowadays, computers are so powerful that even PCs over 10 years old can handle basic functions without issue.
It’s a shame to have a perfectly usable PC that can’t install Windows 11 just because of TPM.

So I’ll show you how to bypass the TPM verification requirement.

Risks of Bypassing TPM

Using the TPM bypass method described below allows you to install Windows 11 even without TPM 2.0.

However, there are a few things to note.
Bypassing TPM may cause some Windows 11 security features to function improperly.
Features like disk encryption (e.g., BitLocker) or biometric authentication (e.g., Windows Hello) may be restricted.

In response to consumer feedback questioning whether TPM 2.0 requirements are overly restrictive,
Microsoft reiterated in December 2024 that TPM 2.0 is a “non-negotiable requirement.” This clarification came as they approached the end of Windows 10 support.

While bypassing TPM 2.0 is possible now, future Windows updates could completely block such workarounds or cease providing security updates.

Additionally, systems installed without TPM become vulnerable to firmware-level attacks or malware like bootkits.
Without the hardware-based security verification provided by TPM, organizations or environments handling critical data should exercise particular caution.

Still, I believe it shouldn’t pose a major problem for typical home use.
You should decide based on your own situation and needs.

For business or official PCs, I recommend replacing them with new hardware at a cost.
For personal PCs that aren’t critically important, bypassing TPM should be acceptable.

Bypassing TPM During Windows Installation

The actual installation process is simpler than you think. Just boot from your Windows 11 installation USB or DVD and proceed.

1. Launch Command Prompt

When the Windows installation screen appears, press Shift + F10 simultaneously.
This will open a Command Prompt window.

2. Launch Registry Editor

Type regedit into the Command Prompt and press Enter.
This will launch the Registry Editor.

3. Create the LabConfig Key

In the left-hand tree menu, navigate to the following path:

HKEY_LOCAL_MACHINE\SYSTEM\Setup

Right-click the Setup folder, select “New” → “Key”.
Name the newly created key LabConfig.

4. Add a DWORD Value

Now, select the newly created LabConfig key in the left tree menu.
Right-click in the empty space on the right, select “New” → “DWORD (32-bit) Value”.

Then create the following 3 entries and set each value to 1:

• BypassTPMCheck: 1
• BypassSecureBootCheck: 1
• BypassRAMCheck: 1

Double-click each entry to edit its value.
Enter 1 in the “Value data” field and click OK.

5. Proceed with Installation

Close the Registry Editor and the Command Prompt.
Now proceed with the Windows 11 installation as usual.
The installation should proceed without TPM requirement errors.

Important Notes

This method allows you to install Windows 11 on older PCs.
There won’t be any major differences in usage after installation.
I’ve installed and used Windows 11 on numerous PCs using this method myself, and found nothing unusual.

However, there’s something to keep in mind.

Since this method artificially bypasses Windows security settings, it could introduce security vulnerabilities.
If the PC handles important data, it’s wise to reconsider.
Ultimately, personal security is your own responsibility.

I hope this information proves useful to you.
Additionally, as a reference, there’s also a method to bypass the TPM requirement during the step of creating a bootable USB using the ISO.
This method is also convenient, so those interested should refer to the content below.
