Windows 11 KB5101650: July 2026 Update Rolls Out, But It’s Blocked on Some Dell PCs

KB5101650 and KB5099414: here are the two updates released by Microsoft on Tuesday, July 14, 2026, for devices running Windows 11 24H2, 25H2, and 23H2. Here’s the key information you need to know about these updates, which are already causing issues on Dell PCs!

Reminder: the July 2026 Patch Tuesday is the largest ever released by Microsoft, with 570 vulnerabilities fixed, including 57 critical ones. Windows 11 alone is affected by 383 of these security flaws. Three zero-day vulnerabilities are also included, two of which are already being exploited in cyberattacks: a privilege escalation issue in AD FS (CVE-2026-56155) and another in SharePoint Server (CVE-2026-56164). These updates therefore fix vulnerabilities in addition to the changes mentioned below.

Depending on the version of Windows 11 you are using, here is the update you will receive:

• KB5101650 is for Windows 11 25H2 (build 26200.8875) and Windows 11 24H2 (build 26100.8875),
• KB5099414 is available for Windows 11 23H2 (build 22631.7376).

In both cases, Microsoft specifies that these cumulative updates include the month’s security fixes, as well as the non-security changes already delivered by the previous month’s optional update. For versions 24H2 and 25H2, this corresponds to KB5095093, released on June 23, which notably introduced the Point-in-time restore feature.

Windows 11: rollout suspended on some Dell PCs

Let’s start with an important note for anyone using Dell machines. On the KB5101650 support page, Microsoft says this update may not be offered on some Dell PCs equipped with an Intel processor. The reason: an incompatibility reported by Dell.

And it is probably better that the update does not reach those machines, given the symptoms mentioned by Microsoft:

• Unexpected shutdowns,
• Reduced performance,
• Overheating,
• Shorter battery life.

Microsoft says it is working with Dell to prevent the affected models from encountering the issue and expects a fix in the coming days. In other words, if KB5101650 is not offered on some of your Dell systems, it is probably a deliberate block on Windows Update’s side. Do not force it, or you may regret it.

The main changes for Windows 11

As with Windows 10, this update for Windows 11 fixes several known bugs and also brings two changes related to Transport Driver Interface and Remote Desktop.

👉 Networking: a hardening change that may break applications

Microsoft has introduced a security hardening measure that requires Transport Driver Interface (TDI) interfaces to be registered. Direct consequence: applications that use sockets over unregistered third-party TDI transports may stop working after this update is installed. Properly registered TDI transports are not affected. This change applies to all three supported versions of Windows 11.

👉 Remote Desktop: SHA-2 certificate fingerprints are now supported

Microsoft is adding support for SHA-2 certificate fingerprints for approved RDP publishers. SHA-1 is still accepted, but only for backward compatibility, and its removal has already been announced for the future. Microsoft’s advice: migrate to SHA-256 fingerprints or a stronger algorithm as soon as possible.

👉 June’s inherited bugs are fixed

The two updates address known issues linked to last month’s update:

• Applications and Office: the issue that prevented some third-party applications relying on OLE automation from launching Office or opening documents has been fixed. It appeared after the June 2026 updates were installed,
• Recycle Bin: the confirmation dialog could display an internal Recycle Bin file name instead of the original name when permanently deleting an item. For Windows 11 24H2 and 25H2, Microsoft says additional scenarios are covered this time, meaning the initial fix was incomplete,
• File Explorer: only for Windows 11 23H2, Microsoft fixes an issue where the OneDrive shortcut in File Explorer stopped working when File Explorer was run as administrator. This fix is not listed on the KB5101650 page. For the record, we previously covered the OneDrive access issues in File Explorer caused by KB5094126.

👉 Keyboard shortcuts: behavior is changing

Microsoft is changing how Windows unregisters and cleans up keyboard shortcuts (hotkeys). In rare cases, some built-in Windows experiences that relied on the old hotkey lifecycle may temporarily stop responding to certain shortcuts. The workaround is simple: restart the affected application. If that is not enough, Microsoft asks users to report the issue through the Feedback Hub.

👉 Secure Boot

As usual, Microsoft continues rolling out Secure Boot certificates. These updates include additional targeting data to expand the scope of devices eligible for automatic deployment of the new certificates. As a reminder, the certificates used by most Windows machines expired in June 2026 (which does not prevent the machines from booting). We published a full guide to anticipating the Secure Boot certificate update.

I encourage you to read my article about KB5095093 to learn more about all the changes.

Windows 11 updates for 2026

These updates are available now through the usual channels, starting with Windows Update. For now, Microsoft says it is not aware of any known issues associated with KB5101650 and KB5099414 (apart from the Dell issue).

Microsoft is also taking this opportunity to remind users of two deadlines to add to your schedules:

• Windows 11 24H2: Home and Pro editions will reach end of updates on October 13, 2026, while Enterprise and Education editions remain supported until October 12, 2027,
• Windows 11 23H2: Enterprise and Education editions will reach end of updates on November 10, 2026.

Below is a summary of the mandatory updates released in 2026 for the various Windows 11 versions.
