To disable Fast Startup in Windows 10, follow these steps:
- Open the Start menu and type "Power & sleep settings," then open it.
- On the right side, click on "Additional power settings."
- In the Power Options window, click on "Choose what the power buttons do" on the left panel.
- Click on "Change settings that are currently unavailable" at the top.
- Under "Shutdown settings," uncheck the box for "Turn on fast startup (recommended)" to disable it.
- Click "Save changes" to apply.
This will turn off Fast Startup, which is a feature that helps to start your PC faster after shutdown by saving the system state. Disabling it means your PC will go through a full shutdown process. This can be useful for troubleshooting or if there are issues with updates or dual-boot systems.
