On October 14, 2025, Microsoft will end support for Windows 10, a shift that will touch more PCs than any sunset before it. After the Windows 10 deadline, systems running Windows 10 will no longer receive free security patches or performance updates, leaving enterprises exposed to escalating cybersecurity risk.
This isn’t just another IT milestone. Windows 10 still powers more than half of the world’s PCs, including hundreds of millions of devices in businesses, schools, and governments. For many, the only path forward will be hardware replacement. The scale of this shift ensures the Windows 10 sunset will ignite a global refresh cycle with ripple effects across the electronic component supply chain. Procurement teams are already feeling the pressure.
Unlike prior Windows sunsets, the 2025 refresh arrives in a uniquely complex moment. Component demand is already shaped by AI infrastructure buildouts, geopolitical realignments, and persistent cost pressures. The Windows 10 deadline overlays a new layer of urgency, and the window for proactive sourcing is rapidly closing.
A Windows sunset is Microsoft’s term for the official end-of-support (EoS) date of an operating system. The Windows 10 sunset date is the point when the company stops providing free updates, patches, and technical assistance. In other words, the software keeps running, but it’s no longer maintained.
Although the Windows 10 sunset date may sound straightforward, in practice, it sets off a chain reaction of risks and decisions for IT teams. Without ongoing support, each device becomes more exposed to cybersecurity threats, compliance issues, and software incompatibilities. The older the system, the greater the risk and the higher the urgency for replacement.
Past examples underscore the impact:
Overall, the Windows 10 deadline in 2025 is projected to be even more disruptive, due to its massive global install base and Windows 11’s stricter hardware requirements.
This refresh cycle stands apart because of scale, and because Windows 11 draws a sharper line between compatible and obsolete hardware. Millions of systems simply won’t meet the requirements for an upgrade.
Unlike prior cycles, this refresh won’t be a one-quarter event. Instead, it will unfold as a multi-year demand driver, affecting component availability well into 2026.
The Extended Security Updates program offers a cushion, but it’s one that comes with limits and an expiration date.
In practice, ESU allows some organizations to stagger migrations into 2026. But rising costs and limited coverage ensure most will still accelerate purchases within the 2025–2026 window.
The bottom line: ESU buys time, not a way out. Hardware replacement is still inevitable.
When an OS reaches end-of-support, the impact doesn’t stop at software, it ripples through the entire component stack.
Windows 11 requires modern CPUs with TPM 2.0. Intel’s 12th–14th gen processors and AMD Ryzen 5000/7000 series are in highest demand.
Lead Times extending and allocation challenges could continue to be even more of an issue in 2026.
GPUs: AI-Driven Demand Convergence
The Windows 10 sunset sets a hard stop for free support. ESU may buy time, but it cannot buy a way out. Hardware replacement is inevitable. The only question is whether you manage it on your own terms or wait until constrained supply forces your hand.
Fusion Worldwide helps procurement leaders get ahead of the Windows 10 refresh curve. Our sourcing experts secure critical components — CPUs, GPUs, DRAM, and storage — before market demand peaks. With our global network and market intelligence, we help ensure supply continuity when authorized channels can’t deliver.

When does Windows 10 support officially end?
Windows 10 support officially ends on October 14, 2025
Can I keep using Windows 10 after end-of-support?
Yes, but without updates it becomes increasingly vulnerable to cyber threats.
What is Microsoft ESU for Windows 10?
A paid program that extends critical security patches for a limited time. It delays risk exposure but does not remove the need for a refresh.
Why can’t most devices upgrade to Windows 11?
Windows 11 requires newer CPUs with TPM 2.0, which excludes millions of older systems.
Which components will see the most demand during the refresh?
CPUs with TPM 2.0, DDR4/DDR5 memory, discrete GPUs, and NVMe SSDs.
How can procurement teams avoid shortages?
By securing allocations early, diversifying sourcing channels, and building buffer inventory.
