System requirements
LanSend is a native 64-bit application that sends pop-up messages to Windows PCs across your local network. This page lists the operating systems it runs on, the minimum hardware, and what you need on the network to deliver a message.
Supported operating systems
LanSend runs on the 64-bit editions of:
- Windows 11
- Windows 10
- Windows Server 2022
- Windows Server 2019
- Windows Server 2016
The same list covers both the machine you run LanSend on and the machines you send to.
Minimum hardware
- 1 GHz CPU
- 512 MB RAM
- 50 MB free disk space
What you need to send a message
LanSend uses the built-in Windows Terminal Services (WTS) messaging channel, so nothing is installed on the recipient and there is no server to set up. To reach a target PC you need two things:
- Network reachability to that PC over the local network.
- Administrative rights on the target.
Once those are in place, you can compose a message and send it from the main window.
