Bugs

 * If you choose "Reset this PC" under Settings - Update & Security - Recovery, the system will be left in an unusable state. The only workaround is to reinstall Windows.
 * You can encounter a  after logging in. The workaround to stop the error is to run the following in Command Prompt with adminstrative rights:
 * The front-facing camera is unusable on PCs that use Intel RealSense. This results in the user being unable to use Windows Hello or any apps that utilize the front-facing camera.
 * Due to a timing issue, there's a chance that airplane mode will incorrectly show as "on" even though WiFi is turned on. The workaround is to toggle airplane mode on and off to get it to show the correct state.
