Setting up a new Windows PC — or cleaning up an old one — doesn’t have to cost a cent. The free software ecosystem for Windows has matured enormously, and today’s best free tools rival (and in some cases beat) their paid competitors. Below is a curated, category-by-category list of the best free programs for Windows 11 and Windows 10, with official download links for each.
A quick note before you start: Microsoft ended official support for Windows 10 in October 2025. If you’re still running it, most of the tools below will still work, but for security and long-term reliability, an upgrade to Windows 11 is worth considering where your hardware allows it. Always download software from the official links below rather than third-party mirrors, which are a common source of bundled adware.
Security & Privacy
Windows Security (Built-in)
You don’t need to install anything extra to get solid baseline protection. Windows 11 and 10 both ship with Windows Security, which bundles Microsoft Defender Antivirus, a firewall, and SmartScreen phishing protection. It’s been scoring well in independent lab tests and runs quietly in the background, making it a genuinely solid default for most home users. Access: Settings > Privacy & Security > Windows Security (no download needed)
Malwarebytes Free
Think of this as a second opinion for your antivirus. The free version runs on-demand scans to catch adware, potentially unwanted programs, and malware that Defender occasionally misses. It doesn’t run continuously in the background on the free tier, so there’s no performance cost — just run a scan whenever something feels off. Download: https://www.malwarebytes.com/mwb-download
Bitwarden
A free, open-source password manager that syncs across all your devices without a paywall blocking basic multi-device use (a common limitation with competitors). It stores logins, generates strong passwords, and includes a browser extension. Download: https://bitwarden.com/download/
System Utilities
Microsoft PowerToys
An official Microsoft toolkit that adds the power-user features Windows should have built in. It includes FancyZones for custom window layouts, PowerToys Run (a fast app launcher), PowerRename for batch file renaming, an always-on-top toggle, a color picker, and a text extractor for pulling text out of images. It’s actively developed and one of the single highest-value free installs for Windows 11. Download: https://learn.microsoft.com/en-us/windows/powertoys/install
7-Zip
The gold standard for file compression on Windows. It opens and creates more archive formats than the built-in Windows tool, compresses files smaller than standard ZIP, and integrates cleanly into the right-click context menu. Completely free and open-source. Download: https://www.7-zip.org/download.html
Everything (by voidtools)
A blazing-fast file search tool that indexes your entire drive and returns results as you type — dramatically faster than Windows’ built-in search. If you regularly hunt for files, this is a must-have. Download: https://www.voidtools.com/downloads/
CCleaner Free
Clears out temporary files, browser cache, and other digital clutter to free up disk space and keep your system tidy. Use it conservatively (avoid the registry cleaner for advanced tweaks) and it’s a handy periodic maintenance tool. Download: https://www.ccleaner.com/ccleaner/download
Rufus
A small, focused utility for creating bootable USB drives — essential if you ever need to install or reinstall Windows, Linux, or run a diagnostic tool from a USB stick. Download: https://rufus.ie/
Productivity & Office
LibreOffice
A full, free replacement for Microsoft Office, including a word processor (Writer), spreadsheet application (Calc), and presentation software (Impress). It handles .docx, .xlsx, and .pptx files with strong compatibility, works entirely offline, and receives regular updates from an active open-source community. Download: https://www.libreoffice.org/download/download-libreoffice/
Notepad++
A vastly more capable replacement for the built-in Windows Notepad. It offers syntax highlighting for virtually every programming and markup language, tabbed editing, and a large plugin ecosystem. Whether you write code, edit config files, or just want a better plain-text editor, this is the standard choice. Download: https://notepad-plus-plus.org/downloads/
Obsidian
A powerful, free note-taking app that stores your notes as local markdown files (so you’re never locked into a proprietary format). It supports bi-directional linking, making it popular for building a personal knowledge base or “second brain.” Free for personal use. Download: https://obsidian.md/download
PDF-XChange Editor (Free version)
A capable PDF reader and light editor that lets you annotate, fill forms, and add comments to PDFs without paying for Adobe Acrobat. The free version does include some limitations (like a small stamp on printed/saved pages), but it’s still one of the most functional free PDF tools available. Download: https://www.pdf-xchange.com/product/pdf-xchange-editor
Media & Entertainment
VLC Media Player
The single most reliable answer to “why won’t this video file play?” VLC plays virtually every video and audio format in existence without needing separate codec packs, and it also handles DVDs, network streams, and subtitle files. It’s been the default recommendation for media playback for two decades for good reason. Download: https://www.videolan.org/vlc/
HandBrake
The standard free tool for converting and compressing video files — useful for shrinking large video files for storage, converting between formats, or ripping video for personal use. Clean interface, no watermarks, and actively maintained. Download: https://handbrake.fr/downloads.php
Audacity
A free, full-featured audio editor and recorder. It handles everything from basic recording and trimming to more advanced tasks like noise removal, multi-track mixing, and format conversion. Popular among podcasters and musicians alike. Download: https://www.audacityteam.org/download/windows/
Shotcut
A free, open-source video editor with a multi-track timeline, support for 4K editing, keyframe animation, and hundreds of filters — with no watermarks on exports. A strong option if you want to edit video without a subscription. Download: https://shotcut.org/download/
Creative & Design
GIMP (GNU Image Manipulation Program)
The most capable free alternative to Photoshop. GIMP supports layers, masks, a wide range of filters, and customizable brushes, and it can open and export most common image formats including PSD files. There’s a learning curve if you’re coming from Photoshop, but the capability is genuinely there. Download: https://www.gimp.org/downloads/
Inkscape
A free vector graphics editor comparable to Adobe Illustrator, useful for logos, illustrations, and scalable graphics. It natively supports the SVG format and is a favorite among hobbyist and professional designers who don’t want a subscription. Download: https://inkscape.org/release/
Krita
A free digital painting program aimed at illustrators and concept artists, with a strong brush engine and animation support. Popular in the digital art and comic community. Download: https://krita.org/en/download/
Screen Capture & Recording
ShareX
A screenshot and screen-recording tool that goes far beyond what Windows’ built-in Snipping Tool offers. It supports scrolling capture, full annotation tools, GIF recording, and automatic upload to cloud services — all completely free with no paid tier. Download: https://getsharex.com/
OBS Studio
The industry-standard free tool for screen recording and live streaming. It supports multiple scenes, audio mixing, and plugins, and it’s used by streamers, educators, and anyone recording software tutorials or gameplay. Download: https://obsproject.com/download
Networking & Diagnostics
Wireshark
A network protocol analyzer that captures and inspects traffic on your network. It’s overkill for casual users, but for diagnosing slow connections, unusual traffic, or general network troubleshooting, there’s no better free tool. Download: https://www.wireshark.org/download.html
Speedtest by Ookla (Desktop App)
A lightweight, no-nonsense way to check your internet connection speed without wading through ads in a browser version. Download: https://www.speedtest.net/apps/desktop
Software & Update Management
WinGet (Windows Package Manager)
Built directly into modern Windows 11, WinGet lets you install and update software from the command line with simple commands — no browsing for installers or worrying about bundled toolbars. It’s Microsoft’s official package manager and is becoming the backbone of many other update tools. Access: Comes pre-installed on Windows 11; verify by typing winget in a terminal, or get it from the Microsoft Store “App Installer” listing.
UniGetUI (formerly WingetUI)
A free graphical front-end for WinGet (and other package managers) that lets you browse, install, and bulk-update software through a simple interface instead of the command line — a good option if you want WinGet’s power without typing commands. Download: https://www.marticliment.com/unigetui/
Ninite
Lets you select a batch of common free programs (browsers, media players, utilities) from a checklist and installs them all at once, silently, with no extra toolbars or bundled offers. Great for setting up a new PC quickly. Download: https://ninite.com/
Browsers
While Windows comes with Microsoft Edge (itself a capable, free Chromium-based browser), many users prefer alternatives:
Mozilla Firefox
A fast, privacy-respecting browser backed by a non-profit rather than an advertising company, with strong tracking protection built in by default. Download: https://www.mozilla.org/firefox/new/
Google Chrome
Still the most widely used browser globally, known for speed and the largest extension ecosystem. Download: https://www.google.com/chrome/
A Few Tips Before You Start Installing
- Always download from official sites. Every link above points to the developer’s own site or a first-party download page. Search engines often surface ad-laden mirror sites above the real one — double-check the URL before clicking install.
- Watch installer checkboxes. Even reputable free tools sometimes bundle optional offers (toolbars, trial software) during setup. Read each screen and uncheck anything you didn’t ask for.
- Keep things updated. Tools like UniGetUI or WinGet make it easy to batch-update everything on this list instead of manually checking each program’s website.
- You don’t need everything on this list. Pick based on what you actually do: a writer might only need LibreOffice and Notepad++; a streamer will want OBS and ShareX; most people will benefit from PowerToys, 7-Zip, and a password manager regardless.
With this set of tools, most everyday, creative, and technical tasks on Windows 11 or 10 are fully covered without spending a dollar — and every program listed here is actively maintained as of 2026, so you’re not installing something that will be abandoned or insecure a year from now.
