Windows 11 requires a compatible 64-bit processor with a minimum speed of 1 GHz and at least two cores, 4GB of RAM, and 64GB of available storage. The system must use UEFI firmware with Secure Boot capability, support Trusted Platform Module (TPM) 2.0, and have graphics hardware compatible with DirectX 12 or later with a WDDM 2.0 driver. A high-definition display with a resolution of at least 720p, measuring more than 9 inches diagonally, and supporting 8 bits per color channel is also necessary. Microsoft provides the PC Health Check app to assess compatibility with Windows 11. If a PC cannot upgrade, users can enroll in the Consumer Extended Security Updates (ESU) program for Windows 10 version 22H2, which extends security updates until October 12, 2027, without introducing new features. Enrollment options include syncing settings for free, redeeming 1,000 Microsoft Rewards points, or paying a fee, with a license applicable to up to 10 devices.
