WakeMeOnLan for Windows

Snapshot: What this tool does

WakeMeOnLan is a free, portable utility from NirSoft that lets you remotely power up and shut down PCs on the same LAN. It also gathers basic network information about discovered machines and can perform some simple diagnostic tasks. Because it’s lightweight and doesn't require installation, you can run it from a USB stick or any workstation.

How it operates

When launched, the program scans the local network to locate reachable devices, records each device’s network details, and stores that inventory to a file for later use. The interface lists every discovered computer and shows key fields such as local IP address, hostname, MAC address, and adapter status. These saved entries let you target individual systems or groups for later wake-up or shutdown operations.

Ways to remotely power machines

You can wake computers using any of these methods:

• Use the command-line interface with the appropriate arguments to trigger Wake-on-LAN packets.
• Click the toolbar button that wakes all selected machines in the GUI.
• Select a computer and choose the wake command from the context menu (or press F8).

Requirements and limitations

Keep the following points in mind before using WakeMeOnLan:

• Wake-on-LAN depends on hardware and firmware support; sometimes you must enable Wake-on-LAN in the system BIOS/UEFI before the OS-level network adapter option will work.
• Packets only travel reliably over wired Ethernet within the same subnet, so wireless clients or devices on different networks may not respond.
• The visual design is functional but dated, and some users might prefer a modernized interface for large-scale deployments.

Who benefits from this tool

System administrators and anyone who manages multiple desktop machines will find this utility useful for remotely powering systems on or off and for assembling a quick inventory of networked PCs. Its portability and zero cost make it a convenient addition to an admin’s toolkit.

Alternatives and final recommendation

If you require commercial support or a more feature-rich, polished product, there are paid Wake-on-LAN offerings and enterprise utilities that add centralized management and reporting. For casual use or small networks, WakeMeOnLan is a practical, recommended option.
