On October 14, 2025, Microsoft will stop providing security updates for Windows 10 unless users enroll in the Extended Security Updates program. Upgrading to Windows 11 may be difficult for PCs older than five or six years due to strict compatibility requirements, including a CPU on the approved list and a Trusted Platform Module (TPM) version 2.0. Users may encounter error messages if their hardware does not meet these criteria. There are workarounds for some users, particularly those with PCs designed for Windows 10, but older devices, especially with AMD processors, may face significant challenges.
To upgrade, users must ensure their PC is configured to start with UEFI, supports Secure Boot, and has an enabled TPM. A registry edit can allow bypassing CPU checks and accepting older TPM versions. Alternatively, a clean installation of Windows 11 can be performed using installation media, which bypasses CPU compatibility checks but still requires TPM and Secure Boot support. Microsoft has introduced new restrictions with the Windows 11 version 24H2 update, requiring CPUs to support specific instructions (SSE4.2 and PopCnt).
For those opting to use the Rufus utility to create installation media, it is essential to use version 4.6 or later to bypass compatibility checks. Users must download the Windows 11 ISO, prepare a USB drive, and follow specific steps to initiate the upgrade process.
