Windows 10 comes with Encrypted File System (EFS) which allows users to encrypt their data in a particular folder or drive. This is especially useful when you want to keep your data private only such that it is accessible from your Windows account only. No one else will be able to open the encrypted files or folders.
EFS is available for all editions of Windows 10 except Windows 10 Home edition. The EFS option is very easy to get access to by just going to Properties of a particular folder and check a check-box that says “Encrypt Contents To Secure Data" in the Advanced tab.
Sometimes, this option is grayed out and you cannot encrypt data in this scenario. This issue is usual and can occur to anyone, as it arises due to misconfigured of registry values.
If “Encrypt Contents To Secure Data" option is grayed out, the following solutions may be helpful in making it work again to start encrypting your personal and private data.
The encryption option may be grayed out because some registry values are not set properly. To resolve this, follow the steps below.
Open Run dialog from the Start Menu and type “regedit" in it to open Registry Editor window.
Now move into following entry in the Registry Editor window. HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\FileSystem
Expand File System key to right-hand window, and look for the key named NtfsDisableEncryption. Double click on it, and set its value to 0.
Save the settings and close all open windows. Go back to “Properties\Advanced\Advance Attribute" option of your required folder which you want to encrypt. The option of encryption will no longer be grayed out.
