How to Disable Fast Startup in Windows

As IT professionals and Managed Service Providers (MSPs), understanding and controlling system features is a part of the job. Fast Startup (also known as Hiberboot or Fast Boot) in Windows 10 and Windows Server 2016, while generally beneficial, may sometimes require to be turned off. In this post, we delve into what Fast Startup is, its implications, how to disable it manually or via PowerShell, and the differences between Fast Startup and Hibernation.

Understanding Fast Startup

Fast Startup, or Hiberboot, works by saving an image of the loaded Windows kernel and drivers into the hiberfile (hiberfil.sys) before a computer shuts down. Upon restarting, Windows uses this image to speed up the boot time, creating a better user experience.

Potential Complications with Fast Startup

However, Fast Startup can present challenges in certain situations:

  • Dual Boot Systems: Fast Startup can cause disk errors or data loss if another operating system accesses the Windows partition.
  • System Maintenance: IT professionals might encounter difficulties when performing system updates or maintenance tasks.
  • Hardware Changes: Fast Startup might not recognize new hardware changes made during shutdown.

How to Manually Disable Fast Startup

To disable Fast Startup manually, follow these steps:

  1. Navigate to the Control Panel and select 'Power Options.'
  2. Choose 'Choose what the power buttons do.'
  3. Click on 'Change settings that are currently unavailable.'
  4. Under 'Shutdown settings,' uncheck the 'Turn on fast startup' box.

Fast Startup vs. Hibernation

Fast Startup and hibernation are similar but serve different purposes. Hibernation saves an image of your work and shuts down your computer, while Fast Startup only saves an image of the system kernel and loaded drivers to reduce boot time.

The Impact of Disabling Fast Startup

Disabling Fast Startup may result in slightly longer boot times. However, the impact is usually negligible on modern systems with fast solid-state drives (SSDs).

Troubleshooting After Disabling Fast Startup

Should you encounter problems after disabling Fast Startup, you can:

  • Check for Windows Updates: Ensure that your system is up to date.
  • Check for Driver Updates: An outdated driver might be causing issues.
  • Re-enable Fast Startup: If problems persist, you might want to re-enable Fast Startup and seek professional assistance.

How to Disable Fast Startup Using PowerShell

For professionals preferring automation, here's a PowerShell script that checks for administrative privileges and modifies the registry to disable Fast Startup:
