Also, I noticed you telling that the problem stated after Windows Update. In case problem still persist or if you really think that the problem started after installing Windows Update, then try to remove that particular Windows Update to see if it makes any difference.
To uninstall an unwanted Windows Update:
Type “View Installed Updates” in the Search box and then click on View Installed Updates – Control Panel from the Search results.
To uninstall the unwanted update, select it from the list and then click Uninstall.
If it prompt for confirmation, just confirm the same. Once it complete uninstalling, reboot your PC and see if it makes any difference.
If uninstalling an update fixes the issue, temporarily block the update from automatically installing again.
If it doesn't fix the issue, then try to perform a System Restore. If an app or update that you recently installed caused problems with your PC, you can restore Windows back to an earlier point in time, called a restore point. System Restore doesn’t change your personal files, but it might remove recently installed apps and drivers.
Note: Windows automatically creates a restore point when you install desktop apps and new Windows updates, if the last restore point is older than 7 days. You can also create a restore point manually at any time.
To restore your PC to an earlier point in time
* Press Windows Key + R to open run command
* Type rstrui and hit Enter key.
* Select Recommended Restore or any other restore point and click Next
* Follow the instructions to restore your PC to earlier. Now see if everything works fine after System Restore.
