How to Enable or Disable Fast Startup in Windows 10

Windows 10 has a Fast Startup setting which allows your PC or laptop to boot with faster speed than normal. It works by saving system info to a file called hiberfil.sys during shutdown, so that next time the system boots, Windows will access this file, read the data that was saved in it and subsequently resume your computer’s session rather than start a new one. You could say that it’s a combination of sleep mode and hibernate mode; that’s why it’s also known as hybrid mode.

For more details regarding this setting, you can read the following related articles:

Fast Startup is turned on by default, but you might want to disable it, or perhaps it was disabled in the past and you are not sure how to turn it back on now. This tutorial will instruct you how to enable or disable it, by using two different methods:

Method (Recommended): Turn On/Off Fast Startup from the Control Panel
Method 2: Turn On/Off Fast Startup by Tweaking the Registry

Note that if you disable hibernation mode, then you won’t be able to use Fast Startup until you enable it again. Furthermore, it should be noted that Fast Startup does not affect restart (i.e. PC is booted normally if you restart, but uses Fast Startup only when it is booted after a shutdown).

Method 1 (Recommended) - Turn On/Off Fast Startup from the Control Panel

This is the typical way one can turn on/off Fast Startup in Windows 10:

Step 1: Open the Control Panel

Right-click on the Start menu or press Win + X (“Win” is the Windows button in your keyboard), and then select Control Panel.

Step 5: Enable Settings that are Currently Unavailable

This screen has the setting we’re looking for at the bottom of the window, but you’ll notice that it’s greyed out. To be able to change it, click on the Change settings that are currently unavailable link at the top of the window first (click Yes if prompted by UAC).

Step 6: Turn On/Off Fast Startup

Now we can configure the Fast Startup setting. Scroll down to the bottom of the window, check the “Turn on fast startup” option and click Save changes to enable Fast Startup. If you want to disable it, uncheck the option instead.

Method 2 - Turn On/Off Fast Startup by Tweaking the Registry

You can follow the steps below to tweak the registry manually in order to enable/disable Fast Startup, or you can jump at the end of the instructions and use the registry files we provide to automatically enable/disable it without messing with the Registry Editor.

Step 1: Open the Registry Editor

Press Win + R (“Win” is the Windows key in your keyboard) to open the Run dialog box, type “regedit” in it (without quotes) and press Enter. The Registry Editor will appear.

Step 2: Locate the Correct Registry Key

From the Registry Editor’s sidebar on the left, navigate to the following directory:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Power

Step 3: Edit the Appropriate Registry Value

In the current registry key find this DWORD registry value: HiberbootEnabled. If its data is set to 0 then Fast Startup is disabled, and if it’s set to 1, then Fast Startup is enabled. So double-click on the registry value, edit the Data textbox in the window that opens (type 1 or 0 depending on whether you want to enable or disable the setting) and then click OK.

Disable Fast Startup.reg
