Your old PC did not get slow — its operating system got heavy. Linux Lite is the Ubuntu-based system designed exactly for this moment — a light Xfce desktop, a Windows-familiar layout, and setup tools that a beginner can actually follow. This guide covers the complete setup, from the download to a ready desktop.
Linux Lite takes the stable Ubuntu LTS base and strips away the heaviness — no Snap store running by default, a desktop that idles on a fraction of the RAM, and a set of Lite tools (Welcome, Software, Tweaks, Drivers) that replace terminal commands with buttons. The order below matters — verify the download, test live, install, update, protect, then add software. Follow it on any old laptop or office PC and you finish with a system that simply works.
👆 The three choices the installer offers. Example wording — pick based on whether Windows must stay on this PC.
Linux Lite is built on an Ubuntu LTS base with the light Xfce desktop, and it is published on one official site — linuxliteos.com. Download the ISO from there only. Lightweight distros are a favourite target for fake download sites that bundle adware into the image, and an operating system is the worst thing to get from a random mirror.
sha256sum linux-lite.iso (use your actual file name) and compare the long string with the siteIf the checksum does not match, delete the file and download again. A mismatch means the download is damaged or tampered with — never install from it.
Write the ISO to a USB pen drive of 8 GB or more with a tool like Ventoy, Rufus or balenaEtcher. Then boot the target PC from that USB — and pause before installing. Linux Lite starts into a live desktop first, which is your free hardware test.
Only start the installer from the desktop icon when the live test passes. A problem found now costs two minutes; the same problem found after install costs an evening.
The installer asks one question that matters more than all others — what happens to the disk. New username, password and timezone screens are routine; this one is not.
First boot lands on a clean Xfce desktop with the panel at the bottom and a menu at the left — deliberately familiar if you are coming from Windows.
The Lite Welcome screen that opens on first boot is not decoration. It is a checklist in disguise, with shortcuts to the exact three things a fresh system needs — updates, drivers and a restore point. Work through it before installing a single app.
Terminal users can do the same update with sudo apt update followed by sudo apt upgrade — same result, and the menu tool is the safer route for beginners.
Two finishing jobs turn a fresh install into a system you can trust. First, a restore point — install Timeshift and take one snapshot now, while everything works. If a future update or experiment breaks something, you roll back instead of reinstalling.
Second, software. Do not roam the internet collecting setup files the Windows way. The Lite Software tool is a one-click shop for the popular apps — browsers like Chrome or Chromium, Zoom, Spotify, TeamViewer and more — each tested to install cleanly on Lite. Your daily basics are already here — Firefox for the web, LibreOffice for documents, VLC for media and Thunderbird for mail, all preinstalled. For everything else, Lite Software first, the Software Manager second, and downloaded setup files last.

▶️ Watch Full VideoYes. Linux Lite is free to download, install and use on as many PCs as you like, at home, in schools and in offices. It is built from Ubuntu LTS and other open source software, and there is no activation, licence key or subscription involved.
Not directly. Windows .exe programs do not run on Linux. Most daily software has a Linux version or an equal alternative — LibreOffice for documents, VLC for media, Chrome and Firefox for the web — and many services work in the browser. If one specific Windows-only program is essential, keep Windows as a dual boot on that PC.
Each Linux Lite series is based on an Ubuntu Long Term Support release, so it receives security updates for years rather than months. Point updates arrive through the normal Install Updates tool, and moving to a whole new series later is a separate, planned upgrade — backup first, as our series upgrade guide explains.
