My PC doesn't have TPM 2.0. How can I force install windows 11?
It is a very challenging job to add a compatible TPM 2.0 chip and you have to upgrade the processor as well. In fact, you can skip these system requirements with software tricks.
This will help you run Windows 11 without TPM 2.0:

I helped me installed Windows 11 on on a HP laptop bought on 2015.
"My PC doesn't have TPM 2.0"-- Installing Windows 11 on a PC that doesn't have TPM 2.0 is technically possible, but it's important to note that Microsoft officially requires TPM 2.0 as a security feature. Bypassing this requirement means your system won't meet the official minimum specifications, which could affect security and supportability.
Recommend the DISM / Image Editing Method if you got this error "My PC doesn't have TPM 2.0". This is for those who like to get their hands dirty with the command line and system image files. It's what the Rufus script is doing automatically. You manually modify the appraiserres.dll file in the Windows 11 ISO, which is responsible for the compatibility check.
How to do it:
- Download the Windows 11 ISO.
- Extract the ISO to a folder on your hard drive (you can use 7-Zip).
- Navigate to the sources folder and find the file appraiserres.dll.
- Rename this file to appraiserres.dll.old.
- Copy the appraiserres.dll file from a Windows 10 ISO (from its sources folder) and paste it into the Windows 11 sources folder.
- Now, use a tool like the free Oscdimg (from the Windows Assessment and Deployment Kit) or another ISO creation tool to repackage the folder into a new, bootable ISO.
- Burn that new ISO to a USB and install.
