Microsoft security update released 2024-10-08. Fixes 2 CVEs.
No exploitation is confirmed for the CVEs in this update and the EPSS exploitation probability is currently 2.9%. That can change: CVEs from past updates regularly get exploited months later, which is why deploying on your normal cadence, without exceptions that linger, is what keeps this one boring.
Most organizations deliver an update like this automatically through Intune update rings, Windows Update for Business, Windows Autopatch, or WSUS; the install section below covers each path.

How to install KB5044021
Any of these paths delivers KB5044021; most organizations already have one of the first three running:
- Intune update rings (Windows Update for Business): the update flows on each ring's deferral schedule.
- Windows Autopatch: rings, rollout, and pause or rollback are managed for you; exploited updates can be expedited.
- WSUS / Configuration Manager: approve KB5044021 for your device groups and set a deadline.
- Manual: download from the Update Catalog above and install; fine for a handful of machines, unmanageable at any real scale.
After the rollout, verify rather than assume: update compliance reporting in Intune or Autopatch shows which devices actually installed it, and Siemserva reads Intune, Defender, Autopatch, and Azure Update Manager together to show the devices still missing KB5044021, ranked by exploitation.
Common questions about KB5044021
Is KB5044021 urgent?
KB5044021 is rated High. Include it in your normal patch cycle unless your environment raises its priority.
How do I download KB5044021?
From the Microsoft Update Catalog (linked on this page), or let Intune, Windows Update for Business, Windows Autopatch, or WSUS deliver it. The catalog page lists the download for each supported product.
How do I deploy KB5044021 with Intune?
