The abbreviation TPM stands for Trusted Platform Module, a security chip built into the computer. Such a TPM module is already installed in most Windows computers of recent years, such as notebooks.
Even assembled desktop computers usually have a slot on the mainboard with which a TPM chip can be retrofitted.
If Windows or software reports that a TPM chip is missing, you can activate it in the UEFI or BIOS if necessary. The TPM chips that are often present are often switched off by default.
Where you can activate an existing TPM module varies from computer to computer and depends on the available UEFI or BIOS. You can usually find the corresponding option in the UEFI, the extended successor to the BIOS that can be operated with the mouse.
The naming depends on the respective hardware. Sometimes the corresponding switch uses the abbreviation TPM.
A different abbreviation is used on certain systems depending on the chipset. In PCs with Intel CPUs you then have to search for PTT for “Intel Platform Trust Technology”. With AMD CPUs, the abbreviation FTPM stands for “Firmware Trusted Platform Module” instead of TPM.
If you find a corresponding option but cannot activate it, your computer is missing the TPM module.
How you can activate a Trusted Platform Module (TPM) in the UEFI (BIOS) is s hown in the following sections using the example of the UEFI of a standard ASUS motherboard.
Activate TPM in the UEFI (BIOS) – this is how it works
After switching on the computer and before the boot process, press the Key to enter the BIOS. On most PCs this is the “Remove”, F2 or F12 key, but there are also PCs with a different setting. In the BIOS you then switch to the UEFI by calling up “Advanced Mode” or similar, and then to the “Advanced – Trusted Computing” area. On some computers you can also find the required option under “Miscellanous” or “Security”.
If your computer does not have a Trusted Platform Module and you want to install Windows 11, you can do that use a trick.
