Many people are finding that the latest cumulative update is giving them fits. Most often it won’t finish installing or, once installed, the USB-connected devices will stop working.
You have several choices–the easiest is to uninstall that update and put off reinstalling it. Some folks find that just rebooting the computer works. When doing this, you may get the screen that tells you that Windows is being repaired. After that, just reboot the computer.
After rebooting, you can re-apply the update and many times that will work.
