Give your PC a boost: 20 free Windows programs worth installing today

Windows can feel faster, cleaner, and more capable with the right apps. I spent years curating a personal toolbox of utilities and everyday programs that solve real problems without costing a dime.

If you’re looking for reliable, well-supported software, this list collects the essentials so you can skip the junk and get straight to productivity, creativity, and safety.

Why these apps made the list

I selected programs based on usefulness, stability, security, and how often they solve problems people actually run into. Each pick is either open-source, widely trusted, or maintained by a reputable team, with an eye toward avoiding bloatware and sketchy installers.

Compatibility with modern Windows versions, minimal system impact, and real-world usefulness were top priorities. Wherever possible I favored cross-platform tools or options with portable builds so you can use them on multiple machines without fuss.

At a glance: the 20 picks

Here’s a quick table to help you scan the list and jump to the programs you care about most. The longer sections below explain why each one matters and how I use them in daily work.

The programs, one by one

VLC Media Player

VLC has been a staple for years because it plays almost everything: MKV, FLAC, obscure AVI files, network streams, and even damaged video files. I keep it on every machine I set up; when Windows Media Player fails, VLC usually saves the day.

It’s lightweight, open source, and free of bloatware when you download it from the official site. If you need subtitles, basic editing, or streaming support, VLC handles those tasks with minimal fuss.

7-Zip

7-Zip offers top-tier compression and extraction for ZIP, TAR, 7z, and many other formats. It integrates with the Windows context menu so zipping and unzipping become a one-click task, which is indispensable if you handle large archives regularly.

Its 7z format often delivers smaller file sizes than ZIP, and the command-line tools make batch operations easy for power users. I use 7-Zip when archiving project folders before backups because it’s fast and reliable.

LibreOffice

LibreOffice provides a complete office suite — word processing, spreadsheets, presentations, and more — without a subscription. Compatibility with Microsoft Office formats has improved dramatically, so it’s a practical choice for most users and organizations.

It includes features many free suites omit, like advanced styles, offline templates, and robust export options to PDF. For occasional Office users, LibreOffice is a straightforward way to avoid recurring payments while keeping full editing capability.

Mozilla Firefox

Firefox focuses on privacy and standards adherence, and it’s an excellent alternative or complement to other browsers. Its tracking protections and extension ecosystem let you customize privacy and performance to your needs.

Over the years I’ve found Firefox especially valuable when testing web pages and when I want a browser prototype isolated from my daily Chrome profile. Use it to split browsing profiles or to avoid extension conflicts.

Google Chrome

Chrome is the most compatible browser for web apps and extensions, and it often offers the smoothest experience with complex sites. If you rely on web-based productivity suites or many browser extensions, Chrome is hard to beat for compatibility and speed.

Be mindful of resource usage: Chrome can be memory-hungry on machines with limited RAM, so use profiles and extensions judiciously. For many workflows, having both Firefox and Chrome installed provides flexibility and a fallback when one behaves oddly.

Visual Studio Code

Visual Studio Code is a fast, extensible code editor that works for casual scripting and full-scale development. It supports many languages out of the box and has an enormous extension marketplace for formatting, linting, debugging, and Docker integration.

I rely on VS Code for web development and for quick edits to configuration files; its integrated terminal and Git support save dozens of context switches per day. The lightweight performance combined with deep features is what makes it indispensable.

Notepad++

Notepad++ is the go-to lightweight text editor for quick edits, log file viewing, and scripting. It opens large files that bog down other editors and supports syntax highlighting for dozens of languages.

When I need to trim a large log, run a regex replace, or quickly view a configuration file, Notepad++ is the fastest tool in my toolbox. The plugin system is simple but powerful for occasional enhancements.

GIMP

GIMP is a mature, open-source image editor that replaces many Photoshop tasks without a subscription. It handles layers, masks, color correction, and advanced selection tools, so it’s perfectly suited for photo retouching and compositing.

There’s a learning curve, but for many users the features and cost (free) make it worth the time investment. I use GIMP for mockups and for preparing images when I don’t want to rely on cloud services.

Paint.NET

Paint.NET sits between Microsoft Paint and GIMP: simpler but capable for fast edits like resizing, cropping, and light retouching. Its interface is approachable and performance is snappy, which makes it great for quick tasks.

When you need something faster than a full-featured editor but more powerful than basic paint tools, Paint.NET hits the sweet spot. Plugins extend functionality, but the core app covers most everyday needs.

OBS Studio

OBS Studio is the free standard for screen recording and live streaming, used by creators and professionals alike. It supports multiple sources, scenes, and high-quality encoding settings, so you can produce polished videos without paid tools.

I use OBS to record screencasts and to stream presentations; the scene switching and audio routing options make it highly flexible for hybrid recordings. It takes a few minutes to master, but the payoff is professional results for no cost.

HandBrake

HandBrake converts video files into efficient, modern formats with plenty of presets for devices and quality levels. Whether shrinking large home videos or re-encoding a movie for portable playback, HandBrake balances speed and quality well.

The batch queue and preset system save time when you have many files to convert, and the constant updates keep codec support current. For archival and casual transcoding tasks, it’s my go-to tool.

ShareX

ShareX is a powerful, no-nonsense screenshot and screencast utility with automation and upload options built in. Capture an area, send it to Imgur or your Teams channel, and have it copied to the clipboard — all in a couple of hotkeys.

I automate repetitive screenshot workflows with ShareX’s custom actions and use it for annotated captures when documenting bugs or creating quick how-tos. It replaces several paid screenshot programs with a single, configurable tool.

qBittorrent

qBittorrent gives you a clean, ad-free torrent client with essential features: search, prioritization, scheduling, and remote management. It’s lightweight, open source, and avoids the junkware or ads found in some other clients.

For large file distribution or retrieving community-shared ISOs and large datasets, qBittorrent is dependable and configurable. Keep usage legal and ethical, and it becomes a useful part of a file-handling toolkit.

VeraCrypt

VeraCrypt allows you to create encrypted containers or encrypt entire drives to protect sensitive data. It’s a successor to TrueCrypt and offers strong, audited encryption algorithms suitable for personal and business use.

Use VeraCrypt when you need local encryption for backups, portable USB drives, or when safeguarding sensitive project files. I keep a small VeraCrypt container for credentials and client notes on a personal drive for extra peace of mind.

KeePassXC

KeePassXC stores passwords locally in an encrypted database that you control, avoiding cloud lock-in unless you choose to sync via your own provider. Its browser integration and auto-type features make logins quick while keeping security tight.

I use KeePassXC for accounts I prefer to keep offline and Bitwarden for cross-device convenience; having both options keeps me flexible and secure. Export and backup your database safely, and use a strong master password.

Everything

Everything indexes file and folder names almost instantly and returns search results as you type. It performs far faster than Windows’ built-in search for locating files by name, helping you find downloads, installers, or nested folders in seconds.

Because it only indexes file names by default, Everything is extremely light on resources and fast even on older machines. I rely on it dozens of times a day to locate screenshots, documents, and project files without waiting.

WinDirStat

WinDirStat creates a visual map of disk usage so you can identify large files and folders quickly. The colorful treemap view makes it obvious where storage is being consumed so you can clean up duplicates and forgotten downloads.

Running WinDirStat before clearing space prevents accidental deletion and speeds up disk maintenance. It’s one of the first tools I run when a laptop is running out of storage — it reveals surprises fast.

Malwarebytes Free

Malwarebytes Free is an excellent on-demand scanner that finds and removes adware and many types of malware that slip past other defenses. It’s not intended to replace real-time antivirus in free mode, but the scanner is a valuable second opinion.

I regularly run Malwarebytes when a machine behaves oddly or after installing new software from less familiar sources. The clean interface and efficient scan make it a practical tool for occasional checks.

Mozilla Thunderbird

Thunderbird is a flexible desktop email client with robust account support, good message handling, and customizable filters. It’s ideal for people who prefer local email archives and heavier control over their inbox than webmail provides.

With add-ons for calendar integration and encryption, Thunderbird can serve as a complete offline email hub. I use it to archive project-related email threads and to keep a local backup of important correspondence.

Bitwarden

Bitwarden is a cloud-synced, open-source password manager that balances convenience with security. It offers browser extensions, mobile apps, and a desktop client for seamless logins and secure password generation.

I keep Bitwarden for accounts I access across devices and KeePassXC for strictly local secrets, enjoying the best of both worlds. If you prefer an easy, audited, and cross-device password solution, Bitwarden is hard to beat for the price — free.

Quick tips for safe downloading and installation

Always get installers from official websites or trusted repositories like the Microsoft Store, GitHub releases pages, or the project’s own domain. Many malicious or bundled installers lurk on search-result ads and third-party download portals, so take the extra minute to confirm the source.

When running a new installer, choose custom install if available and uncheck any optional toolbars or additional software. Keep track of where programs install, and favor portable versions if you want less system clutter.

Keep maintenance simple: a few small routines

Set aside a short maintenance routine: update Windows, run Defender or your antivirus, check Everything for duplicates, and run WinDirStat every couple of months. These small habits prevent slowdowns and keep your machine feeling fresh.

Backups matter: combine a local image backup with an offsite backup or cloud sync. I use a small VeraCrypt container on an external drive for sensitive files, with a cloud-backed copy of less-sensitive documents through Bitwarden-synced credentials and repository services.

How I use this collection in real life

On a typical day I use VS Code for web work, Everything to jump between project folders, and ShareX to capture examples for documentation. For video work I record with OBS, trim and re-encode with HandBrake, and keep raw assets organized with WinDirStat to avoid losing space to old media files.

For security, I run Windows Defender in real time and use Malwarebytes occasionally as a second opinion; KeePassXC and Bitwarden handle passwords depending on whether I need cloud sync. The combination keeps things efficient without paying subscription fees for each category.

Installing these programs transforms a standard Windows install into a capable, secure, and flexible workstation. Pick a few that match your daily needs and add more as new tasks arise — your PC will thank you for the sensible upgrades.
