Microsoft is making a major change to BitLocker encryption in 2026 — here’s what you need to know

by

Microsoft is updating BitLocker, the encryption feature in Windows 11, with a significant speed boost. Starting in 2026, new computers will come with ‘hardware accelerated BitLocker,’ which uses specialized hardware to encrypt data much faster than current methods that rely on the computer’s main processor.

Microsoft has improved BitLocker disk encryption in Windows by using the power of modern processors and system-on-a-chip designs. This means encryption tasks are now handled by dedicated hardware instead of the main processor, making it faster and more efficient. On compatible devices, encryption keys are now secured directly within the processor’s hardware, providing a stronger defense against vulnerabilities and enhancing data protection.

BitLocker has been a feature of Windows since Windows Vista and now automatically encrypts the data on your computer’s main drive. If you sign in with a Microsoft account, your BitLocker key is securely saved in the cloud and can be recovered by logging into the Microsoft Account website.

As a security analyst, I often explain BitLocker to clients as a way to protect their data. Essentially, it makes the information on your PC unreadable to anyone but you. If your laptop were to be stolen, and someone tried to access the data by removing the hard drive and connecting it to another computer, they wouldn’t be able to read anything without your unique BitLocker decryption key. It’s a strong defense against data breaches in case of physical theft.

Windows 11 now comes with BitLocker automatically turned on, but you can disable it if you prefer. Recent updates have made BitLocker even better – it’s now faster and more secure thanks to new technology that encrypts data directly within the computer’s hardware.

Windows 11 is getting a more secure version of BitLocker, along with other improvements. These updates include stronger requirements for driver signing, making it harder for malicious drivers to run. Microsoft is also moving away from relying on custom drivers for devices like keyboards and mice, instead using built-in Windows drivers for better security and stability.
