What is Fast Startup in Windows 11?
Fast Startup in Windows 11 is a hybrid shutdown feature that speeds up boot time by partially hibernating the OS rather than performing a full cold boot each time you shut down.
When you click Shut down with Fast Startup enabled, Windows does this instead of a full shutdown: it closes all user applications and logs you off, then saves the Windows kernel and loaded drivers into the hibernation file hiberfil.sys before powering off the machine. On the next power-on, Windows loads the saved kernel state directly from disk into memory rather than reinitializing the kernel and drivers from scratch, significantly reducing startup time.
How Fast Startup Actually Works
Here’s what happens during a Fast Startup shutdown:
During Shutdown:
- Windows closes all your applications and logs you out of your user session
- All user accounts are signed out completely
- The Windows kernel and loaded drivers remain in memory
- This system state gets saved to the hibernation file (hiberfil.sys)
- Your computer powers down
During Startup:
- Your computer powers on and performs its usual hardware checks
- Instead of loading Windows from scratch, it reads the saved kernel state from hiberfil.sys
- Windows restores the kernel and drivers directly into memory
- You reach the login screen much faster than with a traditional cold boot
The Three Startup Modes in Windows 11
Windows 11 actually supports three different startup modes:
- Cold Boot (Traditional): The complete initialization process, where the boot loader loads all kernel files, configures system functions, and loads all drivers from scratch
- Wake from Hibernation: Restores your entire user session, including all open applications and files
- Fast Startup: Restores only the kernel and drivers (introduced in Windows 8, continued through Windows 11)
Method 1: Turn Off Fast Startup via Control Panel in Windows 11
This is the easiest way to disable Fast Startup in Windows 11. You’ll use the classic Control Panel interface, which gives you direct access to power settings that aren’t available in the modern Settings app.
The entire process takes less than two minutes, and you don’t need any technical knowledge beyond clicking a few buttons. Let me walk you through each step.
- Press the Windows key, type Control Panel in the search box, and click Control Panel when it appears in the results.
- Click Hardware and Sound in the Control Panel window.
- Click Power Options under the Hardware and Sound section.
- Click Choose what the power buttons do from the left sidebar.
- Click Change settings that are currently unavailable near the top of the window, and then click Yes if prompted by User Account Control.
- Scroll down to the Shutdown settings section, uncheck the box next to Turn on fast startup (recommended), and then click Save changes at the bottom of the window.
That’s it! Fast Startup is now disabled on your Windows 11 computer.
Method 2: Disable Fast Startup via Command Prompt in Windows 11
If you prefer working with commands or if the Control Panel method didn’t work for you, Command Prompt offers a quick alternative. This method disables hibernation entirely in Windows 11, which automatically turns off Fast Startup since Fast Startup depends on hibernation to function.
This approach is particularly useful for IT professionals, advanced users who prefer command-line interfaces, or anyone troubleshooting situations where the Control Panel option is missing or grayed out.
- Press the Windows key, type cmd in the search box, right-click Command Prompt in the results, and select Run as administrator.
- Click Yes when the User Account Control dialog appears to grant administrator permissions.
- Type powercfg -h off in the Command Prompt window and press Enter.
- Type exit and press Enter to close the Command Prompt window.
That’s all there is to it! Hibernation is now disabled, Fast Startup is turned off, and the hiberfil.sys file has been removed from your system.
Method 3: Turn Off Fast Startup Using PowerShell in Windows 11
PowerShell offers greater flexibility than the Command Prompt for disabling Fast Startup in Windows 11. While Command Prompt can only disable hibernation entirely (which turns off Fast Startup as a side effect), PowerShell lets you modify the registry directly to disable Fast Startup while keeping hibernation available.
This method is ideal for IT administrators, power users who want fine-grained control, or anyone who needs to script this change across multiple computers.
Checking Current Fast Startup Status
Before making changes, you might want to check whether Fast Startup is currently enabled on your system.
- Press the Windows key, type PowerShell in the search box, right-click Windows PowerShell in the results, and select Run as administrator.
- Click Yes when the User Account Control dialog appears.
- Type (Get-ItemProperty -Path “HKLM:\SYSTEM\CurrentControlSet\Control\Session Manager\Power”).”HiberbootEnabled” and press Enter.
The command will return either 1 (Fast Startup is enabled) or 0 (Fast Startup is disabled). If you see 1, proceed with the steps below to disable it.
Steps to Disable Fast Startup Using PowerShell
- Press the Windows key, type PowerShell in the search box, right-click Windows PowerShell in the results, and select Run as administrator.
- Click Yes when the User Account Control dialog appears to grant administrator permissions.
- Type Set-ItemProperty -Path “HKLM:\SYSTEM\CurrentControlSet\Control\Session Manager\Power” -Name “HiberbootEnabled” -Value 0 and press Enter.
- Type exit and press Enter to close the PowerShell window.
That’s it! Fast Startup is now disabled in your Windows 11 PC through the registry, and the change takes effect immediately on your next shutdown
Method 4: Turn Off Fast Startup Through Registry Editor in Windows 11
The Registry Editor gives you direct access to the registry value that controls Fast Startup in Windows 11. This method is particularly useful when you need to disable Fast Startup but can’t access the Control Panel, or when you want to understand exactly what changes PowerShell makes under the hood. Like PowerShell, this method only disables Fast Startup while keeping hibernation available in Windows 11.
Important: Editing the Windows Registry incorrectly can cause serious system problems. Always back up the registry before making any changes.
How to Backup Registry Before Editing
Before you modify anything in the Registry Editor, create a backup of the specific registry key you’ll be changing. This allows you to restore the original settings if something goes wrong.
- Press Win + R to open the Run dialog box.
- Type regedit in the text box and press Enter.
- Click Yes when the User Account Control prompt appears.
- Navigate to this location: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Power
- Right-click the Power key in the left pane and select Export.
- Choose a save location (like your Desktop or Documents folder), name the file something descriptive like Fast-Startup-Backup.reg, and click Save.
You now have a backup file that you can double-click to restore the original settings if needed. Store this file in a safe location.
Steps to Disable Fast Startup Using Registry Editor
- Press Win + R to open the Run dialog box.
- Type regedit in the text box and press Enter.
- Click Yes when the User Account Control prompt appears.
- Navigate to this registry location: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Power
You can either navigate manually by expanding folders in the left pane, or paste the path directly into the address bar at the top of the Registry Editor window.
- Locate HiberbootEnabled in the right pane and double-click it.
The right pane displays all values stored in the Power key. Look for a DWORD value named HiberbootEnabled. If you can’t see it immediately, scroll through the list or press Ctrl+F to open the Find dialog and search for “HiberbootEnabled”.
- Change the Value data from 1 to 0 and click OK.
The Edit DWORD (32-bit) Value dialog appears. The current value of 1 means Fast Startup is enabled. Change it to 0 to disable Fast Startup. Make sure you’re entering the number zero, not the letter O.
- Close the Registry Editor window.
- Restart your computer for the changes to take effect.
Fast Startup will be disabled when your system boots back up. You can verify this by checking the boot behavior or by returning to the Control Panel, Power Options, to confirm the setting has changed.
Method 5: Turn Off Fast Startup Using Group Policy Editor in Windows 11
Group Policy Editor provides a centralized way to manage system settings in Windows 11, including Fast Startup in. This method is primarily designed for IT administrators managing multiple computers in business environments, but individual users on Pro, Enterprise, or Education editions can also use it. The key difference from other methods is that Group Policy settings take precedence over manual registry or Control Panel changes, making them ideal for enforcing consistent configurations across networks.
Important: Group Policy Editor is only available in Windows 11 Pro, Enterprise, and Education editions. Windows 11 Home users should use Method 1 (Control Panel), Method 3 (PowerShell), or Method 4 (Registry Editor) instead.
Windows Edition Requirements
Before attempting this method, verify your Windows 11 edition:
- Open the Settings app by pressing Windows + I or clicking the Start button and selecting Settings.
- Click System in the left sidebar of the Settings window
- Scroll down and click About.
- Look at the Edition field under Windows specifications.
If it says “Windows 11 Home,” Group Policy Editor is not available by default. Skip to the “Alternatives for Windows 11 Home” section below.
Steps to Disable Fast Startup Using Group Policy Editor
- Press Win + R to open the Run dialog box.
- Type gpedit.msc in the text box and press Enter.
- Click Yes when the User Account Control prompt appears.
- Navigate to: Computer Configuration > Administrative Templates > System > Shutdown
Click the arrow next to each folder to expand it:
- Expand Computer Configuration
- Expand Administrative Templates
- Expand System
- Click Shutdown
The right pane now displays all shutdown-related policies.
- Locate and double-click Require use of fast startup in the right pane.
This opens the policy configuration window. You’ll see three radio button options: Not Configured, Enabled, and Disabled.
- Select the Disabled radio button.
This tells Windows 11 NOT to require Fast Startup. Despite the confusing naming, “Disabled” here means disabling the requirement for Fast Startup, which effectively turns Fast Startup off.
- Click Apply, then click OK.
- Close the Local Group Policy Editor window.
- Restart your computer for the changes to take effect.
After your system restarts, Fast Startup will be disabled, and Group Policy will prevent it from being re-enabled through Control Panel or registry changes.
Why You Should Consider Disabling Fast Startup in Windows 11
Fast Startup can cause several problems in Windows 11 that outweigh its modest speed benefits. Here are the main reasons to disable it:
Dual-Boot System Conflicts
Fast Startup locks Windows partitions in a hibernated state, preventing other operating systems from accessing them properly. When you boot into Linux or another OS, you’ll find:
- NTFS partitions mounted as read-only or refused entirely
- Inability to access shared files or save data
- Potential data corruption if forced write access occurs
Solution: Disable Fast Startup if you run any dual-boot configuration.
Windows Update Failures
According to Microsoft KB4011287, some Windows updates require a full shutdown to complete installation. Fast Startup’s hybrid shutdown keeps the kernel hibernated, preventing these critical updates from applying properly. This results in:
- Updates stuck in installation loops
- Failed security patches
- Incomplete system file replacements
Microsoft’s recommended workaround is to use the Restart option instead of Shutdown, since Restart always performs a full cold boot regardless of Fast Startup settings.
USB and Peripheral Detection Issues
Fast Startup restores drivers from their hibernated state rather than reinitializing them. This causes:
- USB devices are not recognized at startup
- Bluetooth peripherals failing to connect
- Network adapters are showing “no internet.”
- External drives are invisible in File Explorer
- Audio hardware producing no sound
Common fix: Disable Fast Startup to force proper driver initialization on each boot.
Difficult BIOS/UEFI Access
Fast Startup reduces the boot window to access BIOS settings to a fraction of a second, making it nearly impossible to press access keys (F2, Del, F10) in time. This blocks:
- USB boot for OS installations
- Virtualization settings configuration
- BIOS firmware updates
- Secure Boot modifications
Solution: Hold Shift while clicking Restart to access Advanced Startup options, then select UEFI Firmware Settings. This works reliably, though it adds extra steps compared to simply pressing a BIOS key during boot.
Conclusion
Now you know how to turn off Fast Startup in Windows 11, whether that’s a quick toggle in Control Panel, a single command in PowerShell, a registry edit, or a Group Policy pushed across an entire fleet.
The method you use depends on your situation. For a personal machine, the Control Panel or Command Prompt gets it done in under a minute. For IT environments managing multiple machines, PowerShell, Group Policy, or a .REG file gives you the repeatability and control you need.
The trade-off is straightforward: you’ll add a few seconds to boot time, but you get a clean, predictable shutdown every time. No stale driver states, no hibernated kernel sessions, no surprises on the next boot. On any SSD or NVMe drive, that boot time difference is barely noticeable.

Frequently Asked Questions (FAQs)
Fast Startup is a power feature that saves the Windows kernel and loaded drivers to disk at shutdown and restores them at the next boot, reducing startup time.
The option disappears if Hibernate is disabled, because Fast Startup depends on hibernation support. Run powercfg /hibernate on in an elevated Command Prompt, restart, and the option will reappear.
No. Restart always performs a full cold boot regardless of this setting. Fast Startup only affects Shutdown.
Yes, some updates and drivers expect a full cold boot; with Fast Startup enabled, changes may not fully apply until you perform a Restart.
Yes. Windows locks the NTFS partition in a hibernated state, which other operating systems, such as Linux, consider unsafe to mount, often flagging it as read-only or dirty.
No, Hibernate saves the entire session (apps and user state), while Fast Startup only saves the Windows kernel and drivers; after Fast Startup, you still sign in to a fresh session.
