Update summary
Fixes 96 CVEs. Most severe CVSS 9.8 (Critical). EPSS exploit probability up to 32%. Among the top 25% of tracked Microsoft updates by EPSS exploit probability.
A newer security update for Windows 10 Version 1809 for 32-bit Systems has shipped since this one: KB5094041 (2026-08-11). For cumulative update families the newer package includes these fixes, so installing that one is usually the shorter path. Verify against your own update rings before you skip this package.
KB5062572 is the August 12, 2025 rollup for Windows 10 version 1809 and Windows Server 2019, closing 96 CVEs including one rated Critical at CVSS 9.8. None are on the CISA KEV list or tied to ransomware yet, and the top EPSS is a moderate 22 percent, so this is a large-volume patch rather than an active-exploit emergency. Server 2019 fleets are the main concern here given the Critical remote severity and the broad CVE count.
Do this: Deploy KB5062572 to your Windows Server 2019 and 1809 systems in this patch cycle, prioritizing internet-facing servers first.
