How to Change File Sharing Encryption Level on Windows 11 or 10?

The Windows file-sharing feature allows you to share files and printers across a local network. The Printer sharing option lets you make an attached printer available to other computer users on the same Network. Windows uses 128-bit encryption for local sharing, but you can change the encryption level if necessary.

These features of Windows are pretty handy, and you can take advantage of these functions after turning on file and printer sharing in Windows 11/10. Although 128-bit encryption is the standard encryption level for most devices, this isn’t always the case. Some devices require a different encryption level for file sharing. It could be 56-bit or even 40-bit encryption.

Devices that require these less secure encryption methods are not very common now. But an older device may require something other than 128-bit encryption. If that is the case, you will need to know how to change it if you want to be able to share files or connections. This risewindows article will guide you on changing the encryption level for file-sharing connections in Windows 11 or 10.
