W10 ESU problems

Question

Enrolled W10 ESU. Now, I've lost all my USB support, KB5066791 never completes, and I get error 0x8007010b. Help. Thanks.

Answer 1

Did all that . Didn't help.

Answer 2

Hi, I understand how inconvenient this must feel when updates break core features like USB support. The root cause here is usually a mix of corrupted system files and incomplete update components, which can happen after ESU enrollment or when KB5066791 fails mid-install. The quickest way to tackle this is to first repair your system files by running DISM /Online /Cleanup-Image /RestoreHealth followed by sfc /scannow in an elevated Command Prompt. Next, reset Windows Update components by stopping the update services, renaming the SoftwareDistribution and Catroot2 folders, and restarting the services. If the update still won’t install, try downloading the standalone KB5066791 package from the Microsoft Update Catalog and run it manually. Before we go further, can you confirm if your USB controllers show up in Device Manager and whether you’ve already tried DISM and SFC scans?Regards,
Aron

Answer 3

Yes, I can see all my USB composite devices, USB root hubs, USB controllers, and host controllers. But when I plug in a USB Sandisk blade, other USB thumb drive, USB light, or Android phone charger, I get the error message No drivers available. Exception being the Logitech wireless mouse it works and shows as HID-compliant and uses a Microsoft driver out of the system32\drivers folder.

Got it, that detail helps a lot.

Since your USB controllers appear correctly and DISM/SFC scans passed, the issue points to missing or corrupted device-specific drivers rather than the core USB stack.

This often happens after ESU updates because older driver packages get removed or blocked during servicing.

The next step is to manually reinstall the chipset and USB controller drivers from your PC or motherboard manufacturer’s site, then check if Windows Update or optional updates offer driver packages for your devices.

If that doesn’t restore functionality, try forcing Windows to search for drivers by right clicking each affected device in Device Manager and selecting “Update driver” > “Search automatically.”

You can also download the latest Sandisk and other vendor drivers directly if available.

Quick question: are these devices showing up under “Other devices” with a yellow warning icon, or do they appear under “Universal Serial Bus controllers” but fail to load drivers?
