Windows 11 Can I upgrade to Windows 11 without a TPM?

[Melanie335]

My old computer seems to lack TPM 2.0 support. Can I bypass the TPM check and force-install Windows 11 on a computer and on virtual machines? Share your idea or useful script.

As of now, Microsoft has set specific system requirements for installing Windows 11, and one of the primary requirements is TPM (Trusted Platform Module) 2.0 support. TPM 2.0 is a security chip that provides hardware-based, security-related functions.
However, in some cases you can possibly bypass the TPM 2.0 requirement using methods that involve modifying your registry or adjusting BIOS settings if your PC comes with TPM but it's disabled from BIOS. There's also an unofficial method with the use of an ISO file of Windows 11.
On the software level, the Windows 11 Insider Preview ISO can be downloaded and installed without the TPM 2.0 check by editing the appraiserres.dll file. Here's an approximate sequence of steps to do this, although I can't recommend or guarantee the results:
1. Download the Windows 11 ISO. Extract it somewhere, for example using 7-Zip.
2. Go to the 'sources' folder and find the appraiserres.dll file.
3. Open the file with a Hex Editor, find the line containing "83F90B 0F856F 860300" and replace the 0B with 20.
4. Save the file, replace the original file in your Windows 11 ISO with your newly edited one.
5. Then you'd have bypassed the TPM check, and may proceed with the installation.
On the hardware level, go into your BIOS and check if it supports TPM. If it does, it might be turned off, so you could potentially enable it from there.
As for a virtual machine, certain VM platforms such as Hyper-V do emulate a TPM chip, so installing Windows 11 on that VM shouldn't be an issue if the host machine supports Hyper-V with TPM emulation.
Though keep in mind, any unsupported modifications can lead to unexpected issues or even make your operating system unusable. It's also important to note that using these workarounds does not guarantee that updates will be provided for your system once Windows 11 is officially released. It's always recommended to follow the manufacturer's official software requirements. Proceed with caution.

Is this guy reliable? Okay, I'll try it

the AI gives facts but doesn't understand them
yes it is possible to bypass the TPM check but in many cases that just gives you trouble down the road... an older system is not the best way to enjoy W11

what make/ model of system is it?

You can disable the TPM requirement with Rufus but you will lose all Microsoft support and potentially have issues down the road.

I am using the WinBootMate app to bypass the Windows 11 system requirements (unsupported CPU and lack of TPM 2.0) and it worked fine on some old PCs and laptops (ThinkPad T450 from 2015). This app has a built-in feature to skip the system requirements during installation. Here is the screenshot:

Modifying system files to bypass Windows 11 requirements, like the TPM 2.0 check, can technically work, but proceed with extreme caution! While methods such as editing the appraiserres.dll file or modifying the registry are popular, they are unsupported by Microsoft and come with potential risks. Here’s a breakdown to help you decide:

---

Pros of Bypassing TPM Requirements​

1. Flexibility: Allows you to install Windows 11 on older hardware without TPM 2.0 support.
2. Testing Designs: Good for testing purposes and casual experimentation.

---

Risks & Drawbacks​

1. Lack of Official Support:
   • Devices that bypass TPM may not receive critical Windows 11 updates, particularly security patches.
2. System Instability:
   • Modifications to system files can introduce bugs or cause unexpected behavior during installation or while running the OS.
3. Security Limitations:
   • TPM enhances system security features (e.g., BitLocker). Without it, you lose these protections.

---

Safer Alternatives​

• Enable TPM in BIOS:
  • Some PCs have TPM disabled by default. Check your BIOS/UEFI settings and enable TPM or PTT (Platform Trust Technology for Intel).
• Use Windows 10:
  • If bypassing requirements is too risky for you, Windows 10 remains supported until 2025 and is fully functional without TPM.

---

If You Proceed:​

• Before trying it, BACK UP all important data in case something goes wrong.
• Follow reliable tutorials for bypassing TPM checks carefully, or use tools like Rufus Creator (version 3.16+) to modify the Windows 11 ISO in a simpler way.

Let me know if you need a safer specific guide or more details. Either way, good luck with the project, and feel free to ask if you encounter issues!
