The PC market is experiencing a significant shift in 2025 due to the end of support for Windows 10, which is set for October 5, 2025. Windows 11, launched in 2021, requires a TPM 2 for Secure Boot, limiting compatibility to newer devices. Microsoft is phasing out support for older devices due to security concerns, and while older peripherals may still work, they won't receive updates. Microsoft offers extended support options for Windows 10 users, including continued security updates for home users until October 2026 and an Extended Security Updates subscription for corporate users. The transition has led to increased interest in new PCs with neural processing units (NPU) for AI workloads, with support expanding to Intel and AMD systems. The integration of AI capabilities into PCs is being promoted, although current offerings may not incentivize IT departments to invest in NPU-enabled devices. The end of support for Windows 10 has influenced PC purchasing behaviors, resulting in increased shipments as manufacturers prepare for US tariffs. IT leaders must manage their device ecosystems carefully, as unsupported Windows 10 machines could become targets for cyber threats.
