Disable Fast Startup on Windows 10

Scripts Comments Off on Disable Fast Startup on Windows 10

This is a small script that makes changes to the registry that will disable the fast startup feature on Windows 10. This feature can cause potential issues as when a user shuts down their computer with this enabled the computer will go into a sleep/hibernation state instead of powering off as expected.

Additionally this script takes advantage of my logging module.
