Problem with update July 14, 2026—KB5101650 (OS Builds 26200.8875 and 26100.8875)

JDias 186

I just applied the update above (July 14, 2026—KB5101650 (OS Builds 26200.8875 and 26100.8875), and my Start Menu button became non-responsive. I talked with Copilot, and I saw that only SearchHost.exe was running. StartMenuExperienceHost.exe, ShellExperienceHost.exe weren't. My OS is Windows 11 Pro.

A few days before, I had the same problem, and tried to solve it with Copilot. I had to reinstall Windows 11 Pro, mantaining my files and my apps. Copilot made me change the permissions of folders, and that didn't end at all. I had to close the command and, after the re-instalation had to set the permissions by myself.
I think the problem was only permissions.
Now the same problem with the Start Menu appeared again, but I won't follow Copilot.
How can I solve this? Is it the same update?

I have just uninstalled the update (KB5101650) and the functionality of the Start Menu button was re-established. How can I opt out of this update, in order to not be installed in the future? Thank you!

@John DeV Now, my Windows is ready to install the problematic update again... By some reason, I am not able to pause the updates just now...

Sorry for the late reply. Please let the update install first, then uninstall it again. After uninstalling it, immediately pause Windows Updates for 1–2 weeks to prevent the update from being reinstalled automatically.

If the issue is resolved after removing the update, it would also be helpful to submit feedback through the Feedback Hub app. This allows you to notify Microsoft about the problem so their engineers can investigate it and consider a fix in a future update.

I've been having the exact same issue, reverted the update and it fixed it. However after reverting it, the "download & install" is stuck at 0% at all times. And my connection to any application / service either times out, or is stuck with a high ping rate (300-400ms).

Doing the following hasn't fixed my issue :

Flushing my DNS (ipconfig flushdns & registerdns)

Resetting my connection (netsh winsock reset / int ip reset)

Disabling/Enabling the network drivers

Restarting the router

Manually setting the DNS server to 1.1.1.1/8.8.8.8 hasn't resolved this issue.

Restarting my computer on multiple occasions

Disabling/Enabling automatic time & timezone

In-case someone had the exact same issue as me, the solution was to revert the update. And then revert the network driver update if the update keeps failing to install and your internet speed is slow.

@John DeV After some weeks, and some Windows updates, I am having exactly the same issue: Start Menu not responsive. I updated my feedback on Feedback Hub, but I am not receiving any solution (I did it some 24 hours ago). Annexed to my feedback I sent the Reliability Monitor view of one of these issues. Am I getting any response to my update of the feeback?
