In 2026, Microsoft Windows 11 requires specific hardware criteria for installation, including a 64-bit processor (1 GHz or faster with at least two cores), a minimum of 4GB of RAM, at least 64GB of available storage, UEFI firmware with Secure Boot, TPM version 2.0 support, and graphics hardware that supports DirectX 12 or later with a WDDM 2.0 driver. A high-definition display with a resolution of at least 720p and a diagonal measurement exceeding 9 inches is also necessary. Compatibility can be checked using the PC Health Check app, which may take up to 24 hours to reflect recent hardware upgrades. For Windows 10 users unable to upgrade, the Consumer Extended Security Updates (ESU) program provides security updates until October 12, 2027, without new features. Enrollment options include syncing settings for free, using Microsoft Rewards points, or paying a fee, with each license applicable to up to 10 devices.
