Regedit Key to Toggle Fast Startup in Windows 10 and 11

Fast Startup in Windows 10 and Windows 11 reduces boot times by saving the operating system state to a hibernation file during shutdown. While this feature can be configured through the Control Panel, it can also be managed directly through the Windows Registry. The specific registry value that controls this feature is named HiberbootEnabled. This guide provides the exact registry path and step-by-step instructions to enable or disable Fast Startup using the Registry Editor (Regedit).

How to Modify Fast Startup Using Regedit

  1. Press Windows Key + R to open the Run dialog box.

  4. In the right pane, locate the DWORD value named HiberbootEnabled.

    • Note: If this value does not exist, right-click an empty space in the right pane, select New > DWORD (32-bit) Value, and name it HiberbootEnabled.

  5. Double-click HiberbootEnabled to edit it.

  6. Set the Value data field to:

    • 0 to turn Fast Startup Off.
    • 1 to turn Fast Startup On.

  7. Ensure the Base is set to Hexadecimal, then click OK.

  8. Close the Registry Editor and restart your computer for the changes to take effect.

To ensure hibernation is enabled so Fast Startup can function: 1. Open Command Prompt as an Administrator. 2. Run the following command: cmd powercfg /hibernate on
