WireGuard

ApplicationJason A. Donenfeld

Also called wire guard, wireguard windows

Jason A. DonenfeldSecurity

A VPN protocol plus a simple Windows client. The window is wireguard.exe. You still need a server. It is not OpenVPN.

What you need to know

wireguard.exe needs a server. It is not OpenVPN and not NordVPN.

The official WireGuard client imports a config. You still need a peer. OpenVPN uses .ovpn files. Tailscale wraps WireGuard into a tailnet. Consumer VPNs hide the server behind a subscribe button.

What is it?: Protocol plus a simple client. You need a server
Same as OpenVPN?: No. Different protocol and file
Country list?: No. That is a consumer VPN

Feex says

If wireguard.exe is empty, I would ask where the server is. This is not NordVPN. OpenVPN GUI wants an .ovpn, not a WireGuard conf. Tailscale is the mesh product if you did not want to run a server.

What is WireGuard?

WireGuard is a protocol and a simple official Windows GUI. wireguard.exe does not include a vendor server. You add a config.

If you have never used it

If someone handed you a .conf file, this is the official WireGuard Windows client, not OpenVPN. Download it from wireguard.com/install. wireguard.exe imports the config. You still need a server somewhere. NordLynx and Lightway are vendor protocols built on or beside this idea. Tailscale uses WireGuard and adds a mesh. This app is not a streaming-region subscription.

What is it used for?

Import a .conf

IT or your VPS gives you a config. The app does not sell a country list.

Own-server tunnel

You run a WireGuard peer. OpenVPN would use an .ovpn instead.

Not Tailscale by itself

Tailscale speaks WireGuard and adds coordination. This exe will not create a tailnet.

Who is it for?

People who were given a WireGuard config
Admins who run their own peers
Anyone who should not expect Netflix-region servers in this window

Current status

Actively maintained. This article is the official Windows client, not NordLynx inside NordVPN.

How old is it?

Jason A. Donenfeld shipped WireGuard in the late 2010s. The Windows client followed. It is younger than OpenVPN (2001). Current installs are the official wireguard.exe, not a 2018 test driver only.

Versions

Major channels first. Exact build numbers are not all verified here.

Official Windows GUI

wg-quick on other OS (not this article)

System requirements

Values follow the publisher's public guidance. Workload still changes the real need.

Minimum

Minimum system requirements
Operating system	Windows 10 or Windows 11, per wireguard.com install notes
RAM	Light client

Resource profile

CPU demand: Low encryption cost while the tunnel is up
Network demand: Only if you route traffic through the peer

Installed processes

These executables belong to this product when it is installed.

Installed processes
wireguard.exe	Official Windows manager. Needs a config and a server
wireguard.exe	Tunnel service instances use the same family

Startup components

A tunnel can start at logon if you set it in wireguard.exe. That is not a consumer VPN subscription.

File locations

Common WireGuard locations
Typical install	C:\Program Files\WireGuard\

File formats

CONFWG tunnel

Common problems

No config, no tunnel

The app will not invent a country list. You need a .conf from a server you control or a vendor that exported one.

People install this to get NordLynx

NordLynx lives inside NordVPN.exe. This client will not log into Nord.

Getting unstuck

Install from wireguard.com/install

openvpn.net is the other protocol. tailscale.com is the mesh wrapper.

Import the .conf, then activate the tunnel

A leftover OpenVPN GUI profile is a different tunnel.

Check the server is up

A handshake failure is often the peer, not a Windows reinstall.

Alternatives

OpenVPN if you were handed an .ovpn. Tailscale if you want a mesh without running your own peer. NordVPN if you wanted a paid country list.
