Windows 11 is forcing everyone to use TPM chips
Microsoft announced yesterday that Windows 11 will require TPM (Trusted Platform Module) chips on existing and new devices. It’s a significant hardware change that has been years in the making, but Microsoft’s messy way of communicating this has left many confused about whether their hardware is compatible. What is a TPM, and why do you need one for Windows 11 anyway?
So it’s all about security. TPMs work by offering hardware-level protection instead of software only. It can be used to encrypt disks using Windows features like BitLocker, or to prevent dictionary attacks against passwords. TPM 1.2 chips have existed since 2011, but they’ve typically only been used widely in IT-managed business laptops and desktops. Microsoft wants to bring that same level of protection to everyone using Windows, even if it’s not always perfect.
