You don't need to comb through your specs or try to remember when you purchased your laptop to figure this all out. The good news is that this has been a requirement in Windows systems since 2016, so if your Windows laptop was released after that year, you will have TPM 2.0. What has caused much confusion is the need for a TPM, or Trusted Platform Module, a security chip on the CPU. Your display must be at least 9-inches with a 720p or higher resolution, and your graphics card will need to be compatible with DirectX 12 or later with the WDDM 2.0 driver. Other requirements include at least a dual-core 1-GHz 64-bit processor, 4GB of RAM, and a 64GB hard drive. Qualcomm processors made for PCs from the Snapdragon 850 onwards will also work. You need to have at least an 8th Gen Intel Core processor (which launched in late 2017), or AMD's Ryzen 2000 or later. To even run Windows 11, your PC needs to comply with the recommended system requirements. Windows 11 review: System requirements may force you to buy a new PC If you've downloaded Windows 11 but want to revert back to Windows 10, Microsoft gives you 10 days to do so. By that time, Windows 11 should be a well-oiled machine (and you might need to update your hardware anyway). That gives it four more years of important feature updates and security patches before Microsoft takes it out to pasture. If you decline the option to upgrade, that's OK because Windows 10 currently has an end-of-life date of October 14, 2025. You don't have to make the switch to Windows 11, even if your system checks all the compatibility boxes.
