If you’re like most individuals, you didn’t take into consideration whether or not your PC had a TPM (Trusted Platform Module) till Microsoft made it a part of its system necessities to run Windows 11, the upcoming new model of its working system. We’ll clarify what a TPM is, how you could find out whether or not your system has one, and tips on how to allow it if it’s turned off.
What is a TPM?
A TPM, or Trusted Platform Module, is a safety chip that may be embedded in a laptop computer or plugged into most desktop PCs. It’s mainly a lockbox for keys, in addition to an encryption gadget a PC can use to spice up its safety.
For instance, while you boot your PC, one chip wakes up and begins nudging different elements to heat up for the beginning of the day. Once the entire {hardware} is prepared, it goes to the storage drive to begin hauling the working system into reminiscence.
In a safe setting, the PC first makes positive the working system is safe. In reality, it might not even belief the encircling {hardware} it wakened earlier, so it checks them as properly. But with no level of reference, the PC has no concept whether or not any a part of the system has been tampered with. With a TPM, the PC can examine notes utilizing the data saved within the locked-down TPM. If all of it matches, the boot proceeds as regular. If one thing is amiss, purple flags go up.

TPMs are in most newer CPUs
TPM’s initially got here as standalone chips, and initially they have been used solely in company computer systems, the place safety was extra of a priority and prospects would pay the premium for the add-on. More not too long ago, AMD and Intel have built-in firmware-based TPM into their CPUs. That’s made TPM help much more obtainable.
Pretty a lot any Intel CPU from 2013 (suppose 4th-gen Haswell) and constructed for Windows 8.1 ought to have a firmware-based TPM. AMD has supported firmware TPM for a while as properly.
Even if firmware TPM is in place within the CPU, that doesn’t imply each PC has instant entry to it. It may have a BIOS or UEFI replace to help it. While most PCs you purchase from a big PC maker sometimes have it in place, many retail motherboards usually don’t have the BIOS help, or don’t have it switched on by default.
Gordon Mah UngThis Asus Z87 motherboard made for Intel’s 4th-gen Haswell includes a TPM header for an non-obligatory TPM module. On most client desktops, there gained’t be a TPM module put in.
What is a TPM header?
You’ll discover that many desktop motherboards may have an unfilled TPM header possibility obtainable. The header permits for a client to purchase a TPM module for the board in the event that they need to allow a discrete TPM. Most {hardware} offered on to shoppers doesn’t embody the module, as a result of it’s at all times been seen as an additional price.
Gordon Mah UngMost PCs since 2013 have had firmware-based TPM help constructed into them, however it’s off by default.
We don’t truly advocate you do that on a working PC at this level with out making a backup. While some have reported success, others have mentioned it has precipitated sporadic blue-screen errors that didn’t go away even after turning off the firmware TPM within the UEFI.
With Windows 11 nonetheless months away, motherboard distributors will seemingly be releasing new UEFI’s for his or her prospects. You’ll in all probability need to wait till a more moderen UEFI/BIOS is accessible and the OS itself is right here, earlier than taking an opportunity on breaking issues.
Of course, the TPM is simply one of many many belongings you’ll want earlier than you’ll be able to set up Windows 11. You’ll additionally to allow Secure Boot and UEFI mode as properly. Most computer systems made within the final three or 4 years ought to handle the method easily. Older {hardware}, we’ll have to attend and see.
