TightVNC for Windows installs as two distinct pieces, the Server, which you install on the computer you want to access remotely, and the Viewer, which you run on the computer you're controlling from, and it's worth knowing that before installing, since many people only need one or the other, not both. Unlike some remote-desktop tools that are free for personal use only, TightVNC is released under the GPL, so it's genuinely free including for business and commercial use, with no license fee at any scale.
Server vs. Viewer: Installing the Right Piece on the Right PC
The TightVNC Server runs as a background service on the machine you want to reach remotely, say, a desktop in the office, and it's what listens for incoming connections and shares that screen. The Viewer is the lightweight client you run on whichever computer you're connecting from, and it doesn't need to be installed on the remote machine at all.
The full installer package includes both components with a choice during setup, so if you only need to view a remote PC and never expect anyone to connect into your own machine, you can install just the Viewer and skip setting up the Server entirely.
Who ends up using TightVNC
TightVNC is used by IT staff and hobbyists who need free remote desktop access without per-seat licensing costs.
- IT support staff remotely accessing office PCs without commercial licensing fees
- Home users connecting to their own desktop from another room or building
- Mixed Windows and Linux environments needing a cross-platform VNC option
Before you install
A couple of things worth knowing about TightVNC before you request the link: it covers Windows and Linux, so grab the build that matches the machine you're setting up. And on pricing, TightVNC is open source, so the installer is free with no trial timer, feature lock, or upsell screen to click past. It's developed and maintained by GlavSoft.
System requirements
- WindowsWindows 10 or 11 (64-bit); older 7/8.1 builds usually still run but no longer get official support
- Linuxmost current 64-bit distributions; look for a native .deb/.rpm/AppImage or a package in your distro's own repository
Heavier workloads (large files, high-res media, big projects) will naturally want more RAM and a faster CPU/GPU than the bare minimum.
Quick steps
- Download the TightVNC installer for Windows
- During setup, choose Server, Viewer, or both as needed
- Set a connection password on the Server, then connect from the Viewer
TightVNC: the honest trade-offs
- Free under the GPL for both personal and commercial use, no license fee
- Separate Server and Viewer installers let you install only what's needed
- Lightweight footprint compared to many modern remote-desktop suites
- Interface and setup feel dated next to modern remote-access tools
- Lacks built-in file transfer and chat features found in commercial alternatives

Keeping TightVNC up to date
Since TightVNC is open source, most Linux distributions keep it current through their own package manager. On Windows/macOS, re-running the installer from the official site (or an updater built into the app, if it has one) gets you the latest release. Sticking to the developer's own distribution channel — which is what this page links to — means you're never stuck on an old build with unpatched bugs just because a mirror site stopped updating its copy.

Frequently asked questions
Do I need to install both the Server and Viewer on every PC?
No, install the Server only on the computer you want to remotely access, and the Viewer only on the computer you'll be connecting from. Most people only need one or the other on any given machine.
Is TightVNC really free for business use, not just personal?
Yes, it's released under the GPL open-source license, which permits commercial and business use without any license fee, unlike some remote-access tools that restrict free use to personal, non-commercial purposes.
