Essential Windows Software That You Must Have on Your PC

As a Windows user, you have access to an enormous amount of free software. Which ones are trustworthy, and which are the best?

Consult this list for inspiration and to learn about apps you were unaware existed. We are constantly on the lookout for the greatest Windows applications to meet your needs. The majority of applications mentioned on this page are free, and you can easily locate what you’re looking for by exploring the programmes listed by category.


Antivirus software is a cornerstone in protecting your computer from external attacks. While it should not be your only protection, you must install a single antivirus application only! Installing several antivirus tools on the same computer can potentially cause issues, to the point where they lock your computer up.

Bitdefender Antivirus Free Edition

Bitdefender features a dark and straightforward interface with no options overload. The Autopilot mode allows you to “be protected without being bothered.” You get to enjoy the best protection without having to make any decisions yourself. If you want to be completely hands-off with your antivirus protection, Bitdefender should be your #1 choice.

Malware Removal

The following tools complement your antivirus application. While they might have overlapping features, both with your antivirus and each other, you can install one or more of these programs on a single computer.


The popular anti-malware scanner detects and removes worms, trojans, rootkits, rogues, spyware, and any other malware that infected your PC. If you are not interested in the premium version, do nothing after the free trial expires, but remember that you will have to initiate scans manually.

Backup & Sync

When your computer came with Windows 8 or 10, you do not need a fleet of backup tools. The latest versions of Windows come with a built-in Time Machine backup called File History.

PC Maintenance & Security

Third-party applications can affect the performance of your system. They can amass large amounts of temporary files and caches, launch with Windows, and use resources in the background, all while becoming obsolete over time.

Additionally, they can help protect your privacy by erasing evidence of your computer or internet activities.



CCleaner is the PC maintenance gold standard. The award-winning optimisation tool scores high points all around. Clean junk files, make your browsing safer or speed up your startup times. If you have to use its registry cleaner, be sure to back up the registry first.
