Solutions to Backup Your File Encryption Certificate and Key Issue
The Encrypting File System (aka EFS) is a Windows built-in encryption tool to encrypt your files and folder in NTFS file systems. So, only if you have enabled the EFS encryption, you may receive the prompt - "Back up your file encryption certificate and key".
And this usually happens after the first time you encrypt a file or folder or manually create a new key using the Cipher command. In this case, click Back up now (recommended) on the window to protect your file encryption certificate and key.
If you don't use EFS to encrypt your files or folders but still receive this prompt, it is possible that third-party software or malware has enabled EFS encryption and is trying to encrypt your files. In this case, you can choose to find the encrypted files and then decrypt it or directly delete the certificate if you don't find any encrypted files.
