The Encrypting File System (EFS) is a built-in encryption tool that protects private data from unauthorized access. However, some users encounter an issue where the "encrypt contents to secure data" option is greyed out, preventing them from encrypting folders in Windows 10. If you're facing this problem, this guide will help you understand why the Windows 10 encrypt folder greyed out issue occurs and provide 4 effective solutions to fix it.

Improper registry values and corrupted system files can also cause the issue. After considering these factors, you can try the workarounds in the next part to fix the issue.
