Enterprise end-of-life OS prevalence rises ahead of Windows 10 end-of-life
Target Trend
Summary
Hide ▲
Show ▼
Enterprise asset inventories are carrying a significant end-of-life OS burden, with 8.56% of observed assets unsupported and 5% already beyond security support as of Sept. 30. That matters because unsupported systems can remain reachable while no longer receiving security updates. The risk is set to widen further when Windows 10 reaches end-of-life on Oct. 14, expanding the pool of machines that will not get routine fixes. The pattern also shows that some industries are running above the average exposure baseline, making legacy systems an easier target.
