Step-by-Step Tutorial on How to Encrypt Files on Windows 11

Encrypting your files on Windows 11 will render them unreadable to unauthorized users, ensuring that your sensitive information remains secure. Here’s how you can do it:

Choosing ‘Properties’ brings up a window with various tabs, where you can manage different aspects of the file, such as permissions and attributes.

After confirming the changes, Windows will encrypt the file. You might be prompted to back up your encryption key, which is crucial for accessing your files in the future.

Once you complete these steps, your file will be encrypted. Authorized users can still open it, but anyone else will be blocked.
