Windows device encryption enhances data security and only authorized users can access data on encrypted disks. This article discusses common problems and solutions for missing device encryption function, which are suitable for Windows 10 and Windows 11 systems.

Missing device encryption: Problems and solutions

Some users find that this feature is missing or cannot be started when enabling Windows device encryption. This does not necessarily mean that your computer does not support this feature, and the following checks are required:

1. Administrator permissions: Make sure you are logged in as an administrator. In Windows 10, check whether your account type is Administrator via Control Panel -> User Account -> User Account. Windows 11 users can check through Settings -> Accounts.

2. Settings Check: After restarting the device, check whether the device encryption option exists in the settings. Windows 10 users can find it in Settings -> Update and Security; Windows 11 users can find it in Settings -> Privacy and Security.

3. Device encryption support: Device encryption is enabled by default on devices that support modern standby mode. If it is not enabled automatically, please check whether your device meets the following conditions:

• TPM (Trusted Platform Module) 2.0 and supports modern standby mode.
• Supports UEFI (Unified Extensible Firmware Interface) mode.
• TPM is enabled in the UEFI of the device.

How to check whether the device supports device encryption:

1. Open system information (search for "system information" and run as administrator).
2. Look for the Device Encryption Support option in System Summary.
3. If "Prerequisites are met" is displayed, it means support; if "The reason for the automatic device encryption failure" is displayed (such as the TPM is not available, the hardware security test interface fails, the device is not modern standby mode, etc.), it means not supported.

The difference between device encryption and BitLocker:

Device encryption is available for all supported versions of Windows 10 and Windows 11; BitLocker is not available for both Windows 10 and Windows 11 Home.

I hope the above information can help you solve the problem of missing device encryption. Remember, having professional data recovery tools is also an important measure to protect data.
