Notepad access refusal, how to solve the notepad file access denial

You're using EFS encryption. EFS encryption is based on a public key policy. When using EFS to encrypt a file or folder, the system first generates a FEK (File Encryption Key) composed of pseudo-random numbers, and then uses FEK and the Data Expansion Standard X algorithm to create the encrypted file and store it on the hard disk, while deleting the original unencrypted file.

The system then uses your public key to encrypt the FEK and store the encrypted FEK in the same encrypted file. When accessing the encrypted file, the system first uses the current user's private key to decrypt the FEK, and then uses the FEK to decrypt the file. When using EFS for the first time, if the user does not already have a public and private key pair (collectively referred to as keys), the key is generated first, and then the data is encrypted.

If you are logged in to a domain environment, the generation of the key depends on the domain controller, otherwise on the local machine. The EFS encryption system is transparent to the user. This means that if you encrypt some data, then your access to that data will be completely allowed and will not be restricted in any way.

When other unauthorized users try to access the encrypted data, they will receive an "Access Denied" error. The user authentication process for EFS encryption is carried out when logging into Windows, and as long as you log in to Windows, you can open any of the authorized encrypted files. Access is denied because the key is lost after reinstalling the system.

If you don't have a backup before reinstalling the system, it's hard to open the file again.
