Hello,
It is possible that system files might have been damaged or corrupted after installing an update, or that the update installed has known issues.
For resolving corrupted system files, you may run the System File Checker tool to scan and repair the system for corrupted system files. For information about running the tool, kindly see this article.
However, some issues occur only after installing a certain update. An example of a known issue in an update is after installing KB4074588 (latest update), USB devices, such as keyboard or mouse, stop working. Microsoft is already aware of this issue and will provide a resolution through an update. To see the list of known issues for each update, kindly see Windows 10 and Windows Server 2016 update history.
If the System File Checker tool does not help, you can restore your PC from a system restore point. This would take your PC back to a point in time before an update is installed. For information on how to restore your PC from a system restore point, kindly see Recovery options in Windows 10.
After restoring, you may prevent the update from reinstalling by downloading and running the Show and hide updates troubleshooter. To read more about the troubleshooter, kindly read through this article.
If the troubleshooter and the troubleshooting steps mentioned above does not help with resolving the issue after an update, we recommend that you send a feedback directly to Microsoft through the Feedback Hub app. This way, it would let the engineers know how the updates impact your experience and may improve the overall usability of Windows 10. For information about sending feedback, kindly see Send feedback to Microsoft with the Feedback Hub app.
