Fast Startup works by saving critical operating system files in the hibernation drive. Doing so means that your computer can quickly recover previous processes without having to reload them from scratch. It is basically a hybrid of the Windows cold shutdown and hibernation states.  There are plenty of reasons why you may want to turn off Fast Startup. First, it can interfere with your system’s regular update process. Windows Update requires that your PC completely shut down to apply changes. Some systems will prevent you from accessing their BIOS if you use Fast Startup.

Disabling the Fast Startup Feature

  1. First, search and open your Control Panel using the Start menu. Your Control Panel contains most of the settings of your computer. 
  2. Go to Hardware and Sounds > Power Options from the choices provided. You will be redirected to the Power Options page, where you can set preferences related to power consumption. 
  3. On the left-side menu, select “Choose what the power buttons do.” 
  4. Then, near the top of the window, select “Change settings that are currently unavailable.” This will allow you to adjust the options under the Shutdown settings of the same window. 
  5. Under the Shutdown setting section, untick “Turn on fast startup.” Fast Startup will no longer interfere with your shutdown and powerup cycle.
