How to stop automatic BitLocker Device Encryption during install on Windows 11

Windows 11 now enables Device Encryption automatically during installation, starting with version 24H2.
You can prevent the setup from turning on encryption by creating a custom USB bootable media with Rufus or modifying the Registry during installation.
Alternatively, you can turn off the Device Encryption feature on Pro and Home editions from the Settings app after installation.

Starting with the release of Windows 11 24H2, Microsoft plans to enable encryption automatically during the operating system installation for both the Pro and Home editions using the “Device Encryption” feature. However, if you prefer not to use this security feature, you have a few workarounds to install the operating system without encryption or turn off the feature after the setup.

What is Device Encryption?

Device Encryption is a security feature designed to protect your files by encrypting the entire system drive. This ensures your data remains secure and inaccessible to unauthorized users, even if the device is lost or stolen.

On Windows 11, the feature uses the Advanced Encryption Standard (AES) to encrypt documents, pictures, and any kind of data you may have on the computer. It converts data into a format that cannot be read without the correct decryption key, helping protect data from unauthorized access.

In the past, computers were required to meet either Modern Standby or HSTI security requirements, but starting with version 24H2 (2024 Update), the company is making changes to relax the requirements to enable encryption on more devices.

What’s the difference between BitLocker and Device Encryption?

BitLocker and Device Encryption are both security features to provide drive encryption. The difference is that BitLocker is a full-featured encryption tool that is only available on Windows 11 Pro, Enterprise, and Education.

On the other hand, Device Encryption is a simplified version of BitLocker that is available on Windows 11 Home and newer devices running Windows 11 Pro or higher editions. It provides basic encryption features aimed at consumer devices. Also, this feature only encrypts the installation and secondary drives. It does not encrypt external storage connected to the device.

Why turn off Device Encryption?

Although encryption is always a wise idea, there are still valid reasons to disable this feature. Sure, with modern hardware, encryption no longer has the same performance impact, but it can still be a concern for devices with older hardware.

Another reason I can point out is compatibility since some applications or peripherals may not work as expected with an encrypted drive. Also, if you have a dual-boot system, you may encounter issues if you try running Windows alongside Linux on the same computer.

In addition, if you frequently move drives between systems or need to use data recovery tools that do not support encrypted drives, having encryption disabled can simplify these processes. Also, while encryption keys are designed to secure data, losing access to these keys can result in permanent data loss.

In this guide, I will explain several ways to prevent the Windows 11 setup from encrypting your device and the steps to turn off encryption after installation.

Disable Device Encryption using Rufus

To use Rufus to create a bootable media of Windows 11 that disables encryption, connect a USB flash drive with 8GB of space, and then use these steps:

Open Rufus website.
Click the link to download the latest version under the “Download” section.
Double-click the executable to launch the tool.
Click the Settings button (third button from the left) at the bottom of the page.
Use the “Check for updates” drop-down menu and select the Daily option under the “Settings” section.
Click the Close button.
Click the Close button again.
Open Rufus again.
(Optional) Under the “Device” section, use the drop-down menu and select the USB flash drive to create the installation media.
Use the drop-down menu and select the “Disk or ISO image” option under the “Boot selection” section.
Click the down-arrow button (on the right side) and select the Download option.
Click the Download button.
Select the Windows 11 option.
Click the Continue button.
Select the release of Windows 11 to download.
Click the Continue button.
Select the Windows 11 Home/Pro/Edu option.
Click the Continue button.
Select the language of Windows 11.
Click the Continue button.
Select the x64 architecture option.
Click the Download button.
Select the location to save the ISO file automatically.
Choose the “Standard Windows 11 Installation” option under the “Image option” setting.
(Optional) Continue with the default settings after the download.
(Optional) Specify a name for the drive under the “Volume label” setting.
Click the Start button.
Clear all the options (as necessary).
Check the “Disable BitLocker automatic drive encryption” option.
Click the OK button.

Once you complete the steps, you can use the bootable media to perform a clean install of Windows 11 without automatic device encryption.

Disable Device Encryption during setup

To disable encryption during the Windows 11 24H2 installation, use these steps:

Start the PC with the Windows 11 24H2 USB flash drive.
Press any key to continue.
Choose the installation language and format.
Click the Next button.
Choose the keyboard and input method.
Click the Next button.
Select the “Install Windows 11” option.
Check the “I agree everything” option to confirm this process will delete everything on the computer.
Click the “I don’t have a product key” option.

Quick note: The device will activate automatically if this is a reinstallation. If this is a new computer, you must provide a product key.
Select the edition of “Windows 11” your license key activates (if applicable).
Click the Next button.
Click the Accept button
Select each partition on the hard drive where you want to install the operating system and click the Delete button. (Usually, “Drive 0” is the drive that contains all the installation files.)
Select the hard drive (Drive 0 Unallocated Space) to install Windows 11.
Click the Next button.
Click the Install button.
After the installation, use the “Shift + F10” keyboard shortcut to access the first page of the out-of-the-box experience (OOBE).
Type the regedit command and press Enter to open the Registry.

Browse to the following path in the Registry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\BitLocker

Right-click the BitLocker key, choose New, and click the “DWORD (32-bit) Value” option.
Confirm the PreventDeviceEncryption name for the DWORD value and press Enter.
Right-click the newly created key and choose the Modify option.
Change the value from 0 to 1.
Click the OK button.
Click the Close (X) button in the Registry app.
Click the Close (X) button in the Command Prompt app.
Continue with the on-screen directions to finish the version 24H2 setup.

After you complete the steps, the installation of Windows 11 will not be encrypted with BitLocker.

Disable Device Encryption after installation

To disable Device Encryption after the Windows 11 installation, use these steps:

Open Settings.
Click on Privacy & security.
Click the Device Encryption page.
Turn off the “Device Encryption” toggle switch.
Click the Turn off button.

Once you complete the steps, Windows 11 will disable encryption on your computer.

In the case that you want to use your computer with encryption, it’s recommended to back up the BitLocker recovery key as if the unexpected happens, you will have a way to recover.

It’s important to note that many computer manufacturers have been encrypting devices by default for a long time, and the ability to use encryption during installation isn’t new to Windows 11. However, starting with version 24H2, Microsoft will try to enforce the feature more, even when you reset your computer. However, the security feature won’t turn on automatically when upgrading from an older version to 24H2.
