KB5041160: Windows Server 2016 Cumulative Update (August 2025)
The August 2025 Patch Tuesday cumulative update for Windows Server 2016 addresses security vulnerabilities. Windows Server 2016 mainstream support ended January 2022 — if still running it, ensure you are current on extended support patches.
Windows Server 2016 systems missing current cumulative updates are exposed to all unpatched CVEs from the August 2025 cycle and any previous missed cycles. End-of-mainstream-support Windows Server versions attract increased attacker attention as organisations often deprioritise patching on systems scheduled for decommission.
KB5041160 is the August 2025 monthly security rollup for Windows Server 2016. Windows Server 2016 is in extended support until January 12, 2027. Organisations running Server 2016 should plan migration to Windows Server 2022 or 2025 while maintaining current patch status on existing 2016 systems.
Probably yes if any of these apply:
Affected OS versions
An organisation running Windows Server 2016 on several file servers in a "stabilise and migrate" phase delays patching while planning migration. Threat actors specifically target organisations with aging Windows Server versions, using vulnerability intelligence feeds to identify exposure windows. The file servers are compromised via an unpatched local privilege escalation before migration is completed.
