To bypass the TPM 2.0 requirements when installing Windows 11, please follow these steps:

1. Install Windows 11 via an ISO or the Windows 11 Insider Program. While installing Windows 11, if your computer does not meet the hardware requirements, you will see a message stating, "This PC can't run Windows 11."

2. When you see the above message, press Shift+F10 on your keyboard at the same time to launch a command prompt. At this command prompt, type regedit and press enter to launch the Windows Registry Editor.

3. When the Registry Editor opens, navigate to HKEY_LOCAL_MACHINE\SYSTEM\Setup, right-click on the Setup key and select New > Key.

4. When prompted to name the key, enter LabConfig and press enter.

5. Now right-click on the LabConfig key and select New > DWORD (32-bit) value and create a value named BypassTPMCheck, and set its data to 1.

6. Now create the BypassRAMCheck and BypassSecureBootCheck values and set their data to 1 as well.

7. Once you configure those three values under the LabConfig key, close the Registry Editor, and then type exit in the Command Prompt followed by enter to close the window.

8. You will now be back at the message stating that the PC can't run Windows 11.

9. Click on the back button in the Windows Setup dialog.

10. You will now be back at the screen prompting you to select the version of Windows 11 you wish to install. You can now continue with the setup, and the hardware requirements will be bypassed, allowing you to install Windows 11.

Note: It is important to note that disabling these features could affect the performance or stability of Windows 11. Furthermore, by disabling the TPM 2.0 requirement, you are effectively reducing the security in Windows 11. Finally, running Windows 11 on anything less than 4GB will not be an optimal experience and is not recommended.
