Microsoft releases Group Policy patch for KB5043145 issue with USB, Bluetooth, BSOD
A few days ago, we reported that the recent KB5043145 C-release update (non-security preview) was causing serious issues on PCs, resulting in continuous restarts, blue screens, or green screens of death (BSOD / GSOD), as well as booting into BitLocker Recovery through the Windows Automatic Repair Tool.
Today, Microsoft has provided an update regarding the issue, noting that failures related to USB and Bluetooth devices may also occur due to the KB5043145 update.
If you’re experiencing difficulties with USB connections or Bluetooth functionality, the company indicates that a yellow exclamation mark will appear next to these devices in Device Manager (DEVMGMT).
In their statement, the company explained:
This issue also results in USB and Bluetooth connections failing on certain devices. Hardware connected via USB and Bluetooth—such as keyboards, USB memory sticks, printers, and wireless mice—cease to function after installing the update. In these situations, the USB Host Controller in Device Manager will display a yellow exclamation mark.
Currently, Microsoft has issued a Group Policy solution for IT administrators and system admins, enabling affected managed devices to roll back the update via Known Issue Rollback (KIR). This is a standard strategy used by Microsoft to “mitigate”problematic updates when severe issues or bugs arise.
Moreover, the KB5043145 update has also been withdrawn for consumer PCs; however, it may take up to a full day for the solution to take effect.
The company elaborates:
Resolution:
This issue is resolved through Known Issue Rollback (KIR). Please be aware that it may take up to 24 hours for the resolution to automatically propagate to consumer devices and non-managed business devices, as well as business devices that are not overseen by IT departments. Restarting your Windows device may help expedite the application of this resolution.
For enterprise-managed devices under the guidance of IT departments that have installed the affected update and are facing this issue, IT administrators can rectify it by installing and configuring the Group Policy outlined below. The specific Group Policy can be found in Computer Configuration -> Administrative Templates ->.
For instructions on deploying and configuring this special Group Policy, please refer to How to use Group Policy to deploy a Known Issue Rollback.

As usual, Microsoft maintains that they are working to fix these issues in an upcoming update.
