Encrypt Your PC’s Disk Without Sharing Keys with Microsoft

For those looking to encrypt their Windows PC’s disk without storing recovery keys with Microsoft, there are several pathways available. This article outlines the necessary requirements and the steps to achieve this.

Understanding Windows 11 Versions

Only Windows 11 Pro allows users full control over disk encryption. Both the Home and Pro editions support disk encryption, but their functionalities differ significantly.

Disk Encryption Differences

The Home version requires a Microsoft account for disk encryption.
Recovery keys are stored on Microsoft’s servers for Home users.
Windows 11 Pro users can back up their recovery keys independently.

Upgrading to Windows 11 Pro

To utilize the comprehensive features of BitLocker for disk encryption, an upgrade to Windows 11 Pro is required. Users can purchase an upgrade directly through the Microsoft Store for $99. Alternatively, they may acquire a product key from third-party vendors.

Product Key Options

Some vendors, like StackCommerce, claim to offer Windows 11 Pro keys for as low as $10. However, users should exercise caution when purchasing from unofficial sources.

Steps to Upgrade Your Edition

Once you’ve obtained a valid Windows 11 Pro product key, follow these steps:

Open Settings and navigate to System.
Click on Activation.
Select “Upgrade your edition of Windows.”
Click “Change product key” and enter your Windows 11 Pro key.

This process requires only a system restart—no need to reinstall your operating system or worry about losing apps or data.

Post-Upgrade Considerations

After upgrading to Windows 11 Pro, users can reinstall and activate the operating system without re-entering the product key in the future. Ensure you keep your product key safe for potential reactivations after hardware changes.

This guide provides a clear overview for encrypting your Windows PC’s disk independently while avoiding Microsoft’s key storage system. Proper upgrades and encryption methods can secure your data effectively.
