Windows 11 is definitely the focus of all Windows users' attention this year. Even if it is not officially released until October, a lot of users are planning to upgrade their devices so that they can keep up with the Windows 11 minimum requirements. According to detailed information released by Microsoft, computers that support Windows 11 should be equipped with a TPM 2.0 chip and boot in UEFI mode. Changing the boot mode from BIOS to UEFI is easy, users just need to convert the disk partition style from MBR to GPT, and change the boot mode in the BIOS setting. But the TPM 2.0 chip limitation is hard to bypass.

TPM, short for Trusted Platform Module, is a chip that can be integrated into the motherboard of the PC or added to the CPU separately. Its purpose is to protect sensitive data such as encryption keys and user credentials so that malware and attackers cannot access or tamper with these data. The TPM 2.0 chip did not start to be promoted until 2016, so many old PCs do not have this chip.

How to Check If Your Computer Has a TPM 2.0 Chip

How do you know if your computer has a TPM 2.0 chip? You can use Windows's PC Health Check toolkit or a FREE tool - Windows 11 Update Checker to see if your computer is capable of upgrading to Windows 11.
