1. What Is Fast Startup in Windows 11?
Fast Startup is a Windows power feature that helps your computer boot more quickly after a shutdown.
It works by combining elements of a traditional shutdown with Windows hibernation. When Fast Startup is enabled, Windows closes your user sessions but saves the kernel session and loaded system drivers to the hibernation file.
During the next startup, Windows can reload this saved system state instead of initializing everything from scratch.
This is different from a normal restart. Windows Restart generally performs a full Windows boot cycle and does not use Fast Startup in the same way as a shutdown.
Does Fast Startup Improve Boot Time?
It can. The actual improvement depends on your hardware, Windows configuration, drivers, and startup applications.
Computers with traditional hard drives may experience a more noticeable difference than systems with fast SSDs. However, results vary, and some computers may see little practical benefit.
Fast Startup is enabled by default on many Windows installations where the feature is supported.
2. Why Should You Disable Fast Startup?
Fast Startup is useful for many people, but there are situations where turning it off can help.
Fix Hardware Detection Problems
Sometimes, hardware or peripheral issues can be harder to troubleshoot when Windows uses a hybrid shutdown. Disabling Fast Startup can help determine whether the saved startup state is contributing to the problem.
Troubleshoot Driver Issues
Certain driver or firmware combinations may behave differently after a hybrid shutdown. A full shutdown can help when diagnosing issues with network adapters, USB devices, or other hardware.
Disabling Fast Startup is a troubleshooting step, not a guaranteed driver fix.
Improve Dual-Boot Compatibility
If your computer runs Windows alongside Linux, Fast Startup can leave Windows partitions in a hibernated state. Accessing those partitions from another operating system may cause problems or risk data corruption if the filesystem is modified.
Disabling Fast Startup helps avoid this particular hybrid-shutdown issue. You should also disable Windows hibernation if your dual-boot setup requires it and follow the guidance for your Linux distribution.
Perform a Full Shutdown
If you prefer Windows to perform a full shutdown instead of using hybrid shutdown, disabling Fast Startup is a straightforward option.
However, you do not need to disable it simply because you want to restart Windows. The Restart command already performs a full restart cycle.
3. How to Turn Off Fast Startup in Windows 11
The recommended method uses Control Panel. It works on Windows 11 systems where Fast Startup is supported and the relevant settings are available.
Step 1: Open the Power Options Window
Press Windows + R on your keyboard to open the Run dialog box.
Type the following command:
powercfg.cplPress Enter.
Windows will open the Power Options section of Control Panel.
You can also open Control Panel from the Start menu and navigate to Hardware and Sound > Power Options.
Step 2: Select What the Power Buttons Do
In the left-hand pane of the Power Options window, select:
Choose what the power buttons do
This opens the System Settings page containing options for the power button, sleep button, and shutdown behavior.
On some computers, the available settings may vary depending on the hardware and power configuration.
Step 3: Click Change Settings That Are Currently Unavailable
Look for the section labeled Shutdown settings.
If the settings are grayed out, click:
Change settings that are currently unavailable
Windows may request administrator approval. Approve the prompt if it appears.
This action unlocks the shutdown settings so you can modify the Fast Startup option.
Step 4: Uncheck Turn On Fast Startup
Under Shutdown settings, locate the checkbox labeled:
Turn on fast startup (recommended)
Clear the checkbox to disable Fast Startup.
Be careful not to change other power settings unless you intend to modify them.
If the checkbox is already unchecked, Fast Startup is already disabled, so no further change is necessary.
Step 5: Save Your Changes
Click Save changes at the bottom of the window.
Your new setting should now be saved.
If the Fast Startup option is unavailable or missing, continue to the troubleshooting section below.
Step 6: Test the Shutdown Behavior
Save your work and close your applications.
Open Start > Power > Shut down. After Windows shuts down, turn the computer back on.
The next startup should no longer use Fast Startup if the setting was successfully disabled.
You can also use the Restart option when troubleshooting Windows, because a restart performs a full boot cycle regardless of the usual Fast Startup shutdown behavior.
4. Alternative Method Using Command Prompt or PowerShell
If the Fast Startup checkbox is missing, disabling hibernation is another option. Fast Startup depends on the Windows hibernation infrastructure, so turning hibernation off also disables Fast Startup.
Important: This method disables hibernation entirely, not just Fast Startup. It also removes the ability to use Hibernate and may affect features that depend on hibernation.
Step 1: Open an Administrator Terminal
Right-click Start and select Terminal (Admin) or search for Command Prompt and choose Run as administrator.
Approve the User Account Control prompt if necessary.
Step 2: Run the Power Configuration Command
Enter the following command:
powercfg /hibernate offPress Enter.
The command disables hibernation on the computer. As a result, Fast Startup will also be unavailable.
The command may run without displaying a success message. That is normal.
Step 3: Verify the Result
Open Control Panel > Hardware and Sound > Power Options > Choose what the power buttons do.
Check the Shutdown settings section. The Fast Startup option should no longer be available while hibernation is disabled.
How to Re-enable Hibernation
If you want to restore hibernation later, open an administrator terminal and run:
powercfg /hibernate onAfterward, revisit the Power Options settings. If Fast Startup is supported, its checkbox may become available again.
You can then decide whether to enable or disable it.
5. Common Errors and Fixes
Fast Startup Option Is Missing
Possible cause: Hibernation is disabled, or the feature is unavailable due to the system configuration.
Fix: Open an administrator terminal and run:
powercfg /hibernate onReturn to the Power Options page and check whether the Fast Startup option appears.
If it remains missing, check your computer’s power configuration and Windows edition. Avoid changing registry settings without a specific reason.
The Checkbox Is Grayed Out
Possible cause: You have not unlocked the settings or do not have sufficient administrative permissions.
Fix:
- Open Power Options.
- Select Choose what the power buttons do.
- Click Change settings that are currently unavailable.
- Approve the administrator prompt if required.
If your computer is managed by an organization, Group Policy or other management settings may restrict changes.
Fast Startup Turns On Again
Possible cause: A power policy, system-management tool, or configuration change may have altered the setting.
Fix: Reopen Power Options and check the current checkbox state. On a work-managed computer, contact your IT administrator before attempting to override organizational policies.
Windows Still Starts Slowly
Disabling Fast Startup is not a general boot-performance fix. It may actually increase startup time because Windows no longer restores the saved kernel session during shutdown-based startup.
If Windows is slow to start, investigate startup applications, available disk space, Windows updates, driver health, and the system’s overall performance.
The PowerShell Command Does Not Work
If powercfg /hibernate off returns an error, confirm that you opened an administrator terminal and entered the command correctly.
You can also check the available power configuration options using:
powercfg /?If the problem continues, record the exact error message before attempting additional system changes.
6. Best Practices and Pro Tips
Use Control Panel first. If your goal is only to disable Fast Startup, unchecking the dedicated setting is the most direct method.
Do not disable hibernation unnecessarily. The powercfg /hibernate off command disables more than Fast Startup. Use it only if you understand the consequences.
Use Restart when troubleshooting. Restarting Windows is often sufficient to test whether a driver or temporary system issue persists after a fresh boot.
Consider your hardware. Disabling Fast Startup may increase the time required to start your PC after shutdown. Test the change to see whether it improves reliability.
Keep Windows and drivers updated. Firmware and driver updates may address hardware behavior that initially appeared to be related to Fast Startup.
Check other Windows settings when needed. For example, if you’re troubleshooting other built-in Windows utilities, see our guide on how to enable Windows Fax and Scan in Windows 11.

7. Frequently Asked Questions
1. How do I turn off Fast Startup in Windows 11?
Open Run using Windows + R, enter powercfg.cpl, and press Enter. Select Choose what the power buttons do, unlock the settings, clear Turn on fast startup, and save your changes.
2. Is it safe to disable Fast Startup in Windows 11?
Yes. Disabling Fast Startup is generally safe. It changes how Windows starts after shutdown but does not uninstall Windows or delete your personal files.
3. Why is Fast Startup missing in Windows 11?
The option may be missing because hibernation is disabled, the system does not expose the feature, or the power configuration is restricted. Enabling hibernation may make the option available.
4. Does disabling Fast Startup make Windows 11 slower?
It can increase startup time after a shutdown because Windows performs a full boot instead of restoring the saved kernel session. The difference depends on your hardware and system configuration.
5. Can I disable Fast Startup using PowerShell?
Yes. Run powercfg /hibernate off in an administrator terminal to disable hibernation, which also disables Fast Startup. However, this also disables the Hibernate feature. To disable Fast Startup alone, use the Control Panel checkbox when available.
8. Conclusion
Fast Startup can help Windows 11 boot faster after shutdown, but it is not essential for every computer.
To turn it off, open Power Options, select Choose what the power buttons do, unlock the settings, clear Turn on fast startup, and save your changes.
If the option is missing, check whether hibernation is enabled. You can use powercfg /hibernate off as an alternative, but remember that it disables hibernation as well.
After changing the setting, test your computer to determine whether the change resolves your specific issue. If startup problems continue, investigate drivers, startup applications, and Windows system health rather than assuming Fast Startup is the cause.
