IDC: global PC shipments rose 9.6% YoY to 76.4M units in Q4 2025, helped by Microsoft ending Windows 10 support and OEMs pulling forward inventory amid tariffs
Context & Ripple Effects
The PC market has repeatedly benefited from replacement cycles: IDC and Gartner tied the 2019 shipment rebound to a Windows 10 refresh. A subsequent 3% increase in Q2 2024 indicated that the category was already recovering before the latest acceleration.
This quarter combines a software-support transition with tariff-driven inventory timing. That matters because the reported gain reflects both customer upgrades and supply-chain scheduling, which can produce different follow-on demand patterns.
First-order effects
- Microsoft’s end of Windows 10 support pushes organizations and consumers still on older systems toward upgrades, lifting near-term demand for OEM PCs.
- OEMs that advanced inventory ahead of tariffs have more units positioned in the channel, while Q4 shipment totals partly reflect the timing of those purchases rather than final sell-through alone.
Second-order effects
- PC makers and retailers face a sharper contest for upgrade budgets, with Windows migration, device availability, and tariff exposure becoming immediate differentiators.
- Pull-forward inventory can reduce the need for near-term replenishment after the pre-tariff buying window, making subsequent shipment comparisons less indicative of underlying PC demand.
Third-order effects
- The episode reinforces that mature PC-market growth is increasingly event-driven—by operating-system support deadlines and trade-policy timing—rather than a uniformly expanding replacement market.
- If such timing effects recur, investors and suppliers will need to separate channel inventory movements from end-user demand when assessing the durability of PC recoveries.
The trend: PC demand is becoming more cyclical around forced upgrade events and supply-chain policy shifts, making shipment growth more dependent on timing than on steady category expansion.
