The best free software stack for a new Windows PC

A free Windows setup should be more than a list of downloads. The source of each installer, the update method, file compatibility, and backup plan matter as much as the application name. A computer full of abandoned utilities from download portals is not a good free-software stack.

The collection below covers the jobs most home and student PCs need: browsing, office documents, PDFs, archives, media, passwords, images, video, search, and backup. Install only the categories you use. Fewer applications mean fewer updates and fewer opportunities for bundled junk.

The core free Windows stack

Choose one app per job. Installing LibreOffice and ONLYOFFICE can make sense while testing compatibility, but you do not need three PDF readers, two antivirus products, or a collection of overlapping “PC optimizer” tools.

Install software safely

Use one of three sources: the Microsoft Store, Microsoft's WinGet package manager, or the developer's official website linked from a verified project repository. Confirm the product name, publisher, domain, and installer signature before approving an elevation prompt.

Leave Windows Security's reputation-based protection enabled. Microsoft recommends enabling blocking for both potentially unwanted apps and downloads. A warning is a reason to stop and verify the file, not a dialog to dismiss automatically.

Use WinGet for repeatable installation

WinGet is included with modern Windows through App Installer. It can search, show, install, uninstall, and upgrade packages from a terminal. Search first, inspect the exact package, and restrict the source so that a similar name does not select the wrong program:

winget search "7-Zip"
winget show --id 7zip.7zip --exact --source winget
winget install --id 7zip.7zip --exact --source winget

Read the displayed publisher, version, installer URL, and agreements before installing. A package-manager entry helps repeatability but does not remove the need to verify what you are adding. People who strongly prefer a graphical interface can use Devolutions UniGetUI, which manages WinGet and other package systems in one window. Supporting several sources also creates more choices, so beginners should enable only what they understand.

Recommended installation order

1. Finish Windows Update: install system and driver updates offered by Windows, restart, and check again.
2. Protect recovery: save important files and the BitLocker recovery key, if device encryption is enabled, before major cleanup.
3. Remove trials normally: use Settings → Apps → Installed apps for unwanted OEM trials. Restart before installing replacements.
4. Check security: confirm real-time protection, firewall, reputation-based protection, and potentially unwanted app blocking are active.
5. Install the foundation: browser, password manager, 7-Zip, office suite, PDF reader, and VLC.
6. Migrate and test: import bookmarks and passwords, open representative DOCX/XLSX/PPTX and PDF files, then set default apps.
7. Add creative tools: install image or video editors only after confirming hardware requirements and file formats.
8. Create a backup job: copy irreplaceable files to a second device or trusted storage and perform a test restore.

Keep the stack updated

Allow trusted applications to use their built-in automatic updater. Once a month, open a terminal and preview packages that WinGet can update:

winget upgrade

Review the list before applying updates. To attempt all available upgrades, use:

winget upgrade --all

WinGet cannot update every application: some installers do not expose a usable version or are managed by another store. Also check Microsoft Store → Library and the update screen of specialist applications. Restart after system or security updates and verify that essential work still opens correctly.

What not to install

• Cracks and activators: they are illegal in many contexts and a common route for credential theft and malware.
• Registry cleaners and “one-click optimizers”: they can remove useful settings without producing a meaningful performance gain.
• Third-party driver updaters: use Windows Update or the hardware manufacturer's official support page.
• Codec packs: VLC already plays most common media formats without modifying system-wide codecs.
• Random debloat scripts: a script can remove recovery, security, Store, or update components you later need. Uninstall known unwanted apps individually.
• Multiple real-time antivirus suites: overlapping security products can conflict and slow the computer.

This stack is deliberately conservative: trusted sources, a small set of established tools, and a visible update routine. Free software saves money only when your documents remain compatible, your data is recoverable, and the computer stays secure.
