Microsoft has released KB5083769 as the April 14, 2026 cumulative security update for Windows 11 versions 24H2 and 25H2. The update moves systems to OS Builds 26100.8246 and 26200.8246. This is the month’s Patch Tuesday release, so it brings security fixes, stability improvements, Secure Boot changes, and one known issue that matters more to IT-managed devices than home PCs.
For most users, it will arrive like a regular Windows Update. For businesses, this patch is more important because Microsoft is already warning that Secure Boot certificates used by most Windows devices begin expiring in June 2026. That gives KB5083769 extra relevance, especially in organisations using BitLocker and tighter boot security policies.
KB5083769 Is Now Rolling Out Through Normal Channels
Microsoft says KB5083769 is available through Windows Update, Windows Update for Business, WSUS, and the Microsoft Update Catalog. On consumer machines, it should install automatically. If a PC already received the latest March 2026 cumulative updates, Windows downloads only the new parts included in this package.
The update also adds more visibility around Secure Boot certificate status. On supported devices, Windows Security can show status badges and notifications related to certificate updates. Microsoft says these alerts are disabled by default on commercial devices, which suggests a more controlled rollout for managed fleets. Microsoft’s official security channels also signalled that April 2026 security updates were available.
The Main Fixes Users Will Actually Notice
The biggest changes focus on security and reliability. Microsoft says the update improves device targeting for new Secure Boot certificates and fixes an issue that could push some devices into BitLocker Recovery after Secure Boot updates.
There are also two useful practical fixes. SMB compression over QUIC is now more reliable, which should reduce timeout problems during file transfer sessions. Remote Desktop also gets stronger phishing protection. When an .rdp file is opened, Windows now shows all requested connection settings before connecting, with every setting turned off by default. A one-time warning also appears the first time an .rdp file is opened on a device.
A Quiet But Important Recovery Fix
Microsoft also fixed a bug that could cause “Reset this PC” to fail after the March 2026 Hotpatch update, whether users chose “Keep my files” or “Remove everything.” It is not the flashiest repair, but it matters when a machine already needs recovery.
The Known Issue That Deserves Attention
Microsoft has added one known issue to the release notes. Some devices may ask for the BitLocker recovery key on the first restart after installing KB5083769. The company says this affects only a limited number of systems and is unlikely on personal devices that are not managed by IT.
The risk appears only when several conditions are true at the same time, including BitLocker on the OS drive, a specific Group Policy setting, PCR7 binding reported as “Not Possible,” and the presence of the Windows UEFI CA 2023 certificate. Microsoft recommends auditing BitLocker policy settings before deployment or using a Known Issue Rollback where necessary.

What Users Should Do Before Installing
Most home users should install KB5083769 normally and restart when prompted. Businesses should take a slower path by checking BitLocker policy settings, confirming PCR7 status, and reviewing Microsoft’s release health notes before broad deployment. Copilot+ PCs may also receive bundled AI component updates, while standard Windows PCs and Windows Server will not install those AI components. Overall, this looks like a useful April 2026 security update, but the best approach this month is to patch promptly with awareness.
