Change File Sharing Encryption Level in Windows 11 and 10

The File sharing feature allows you to share files and folders with others on the same network. The feature is quite useful and we can easily turn on the file and printer sharing feature in Windows 11/10 but Windows uses 128-bit encryption to help protect file sharing connections by default . On the other hand, Some devices do not support 128-bit encryption and must use 40- or 56-bit encryption for example your older operating systems may use only 40-bit or 56-bit encryption for file sharing.
