How to Change File Sharing Encryption Level in Windows 10
File and printer sharing is the ability of a computer running Windows to share a folder or attached printer with other computers on a network.
- File sharing allows you to make files and folders in a shared folder accessible to others on the network to view, copy, or modify.
- Printer sharing allows you to make an attached printer available to other computer users on the network.
Windows uses 128-bit encryption to help protect file sharing connections by default. Some devices do not support 128-bit encryption and must use 40- or 56-bit encryption.
This tutorial will show you how to change to use 128-bit or 40- or 56-bit encryption for file sharing on all networks in Windows 10.
You must be signed in as an administrator to change the file sharing encryption level.
