However, not every existing Windows 10 PC will be able to update to Windows 11. TPM 2.0 (Trusted Platform Module) support, 4GB of RAM, and 64GB of storage will be required with Windows 11. Intel 8th Gen Coffee Lake or Zen 2 CPUs and higher will be required. Millions of PCs will be unable to upgrade to Windows 11, while unsupported solutions will be available if you really want Windows 11.
