Microsoft reported a 27% decline in Windows OEM revenue for the quarter ending September 30, 2026, as the global PC market contracted by 21%. This downturn follows a period of elevated demand driven by hardware refresh cycles.

Why it matters

The decline reflects a cooling market after a period of high demand linked to Windows 10 end-of-support cycles, compounded by rising component costs for RAM, SSDs, and processors that have suppressed new PC shipments.

Windows 11 currently holds a 71.44% share of global online Windows PCs, while Windows 10 retains 27.82%. Microsoft has extended free consumer security updates for the latter until October 12, 2027.

The players

Microsoft

A multinational technology company primarily known for its Windows operating system, cloud computing platforms, and hardware devices.

The details

Microsoft earns OEM revenue by licensing its operating system to PC manufacturers for preinstallation on new hardware. The current revenue drop is attributed to PC makers working through existing inventory and reducing license orders. Meanwhile, higher market prices for core components like processors and memory modules have hindered new shipment volumes globally.

Timeline

  1. Global PC shipments grew 8.2% in Q3 2025.

  2. Windows OEM revenue fell 27% between July and September 2026.

  3. Windows 10 market share stood at 27.82% in September 2026.

  4. Microsoft held its fiscal year 2027 first-quarter earnings call on October 28, 2026.

  5. Windows 10 security update support ends on October 12, 2027.

The Tech Race

This decline marks a departure from the growth trajectory seen in 2025 as the market shifts from a high-refresh environment. Microsoft now faces a mid-thirties revenue decline projection for the final quarter of 2026.

Users currently running Windows 10 retain access to free security updates until October 2027, providing a longer runway for hardware replacement. Those shopping for new PCs may face higher prices due to elevated costs for memory and storage components.

The takeaway

The PC market is currently recalibrating after a period of intense hardware replacement cycles. Analysts should watch the October to December 2026 revenue guidance to see if the mid-thirties decline projection holds as component pricing fluctuates.
