Microsoft releases record-breaking July 2026 Patch Tuesday for Windows 11

Microsoft rolled out the July 2026 Patch Tuesday cumulative update (KB5101650) for Windows 11 (versions 24H2 and 25H2). The update closed a record number of security flaws – reports cite more than 570 CVEs, with some analyses counting 621 or 722 disclosures – and includes two zero‑day vulnerabilities that were already being exploited in the wild.

Key new capabilities added in the update are Point‑in‑Time Restore (automatic system snapshots kept for up to 72 hours), a calendar‑based pause option for Windows Update, refined widget‑panel behavior, a screen‑tint eye‑comfort feature, and extensive Bluetooth stability improvements. The patch also resolves a severe storage bug in the CapabilityAccessManager .db‑wal file, which could inflate to hundreds of gigabytes and consume up to 500 GB of disk space. Users are advised to check the file size and delete it manually if it remains oversized after installing the fix.

Microsoft temporarily halted the rollout for certain Dell PCs after reports of unexpected shutdowns, overheating and battery drain caused by an incompatibility between an Intel driver and the new USB‑C Connection Manager interface. An out‑of‑band cumulative update (KB5121767) was later made available for affected devices. The update also patches critical components in SharePoint, Active Directory Federation Services, Chromium‑based Edge, and other Microsoft products, while support ends for older server versions.
