30 Essential Pieces of Free (and Open) Software for Windows

We live in a golden age of computer software, where there are freely available software packages for almost any purpose. But isn’t there no such thing as a free lunch? Who makes free software, and why?

Some free software is the result of people simply writing programs that they find useful and sharing them with others. Some free software is ad-supported. Other free software packages are given away using the “freemium” model, which means the basic version is free with some advanced features available for paying customers. Still other free software packages are made available by large companies as enticement to get you to try their other software.

With these options and the easy access to software that the internet provides, there are tons of great software choices out there that you don’t have to pay a dime for.

    What about malware?

    One concern many people have with free software is malware. Malware can do any number of things to your computer, including identity theft and holding your files for ransom.

    There are several simple steps you can take to avoid malware. First, only download software directly from the official app store of the platform you’re using or directly from a well-established software company. For Windows, the place to start is Windows Apps. You should also strongly consider an antivirus software package. At minimum, use Microsoft’s Defender, which is free with Windows.

    Free software for Windows

    Microsoft OneDrive

    What does it do? Online backup
    Microsoft OneDrive is Microsoft’s online backup solution that’s integrated heavily with Windows. It includes 5 GB of storage for free. This is great for backing up important but not highly personal material, like digital photographs.

    Alternate option: Dropbox Basic, http://www.dropbox.com/

    Mozilla Firefox

    What does it do? Web browser built for security
    Although Windows comes with a built-in web browser, Mozilla Firefox is a great alternative as it’s designed from the bottom up for security. It blocks third party tracking cookies and social trackers by default, meaning advertisers keep their nose out of your web browsing as much as possible.
    URL: https://www.mozilla.org/en-US/firefox/new/
    Alternate option: Google Chrome, https://www.google.com/chrome/

    Windows Storage Sense

    What does it do? Automatic junk file remover
    Many software packages download things like web pages and extra files to your computer and then never delete them. Windows Storage Sense, which is already a part of many versions of Windows, automatically takes care of those excess files, maximizing the free space on your computer for files you actually care about — applications, photos and so on.
    URL: https://support.microsoft.com/en-us/windows/free-up-drive-space-in-windows-10

    Ultra Defrag

    What does it do? Speeds up your hard drive
    Over time, as you add more files and programs to your computer, they become internally disorganized. Think of a filing cabinet where new files are just stuffed at the front. Ultra Defrag organizes the “filing cabinet” under the hood of your computer, which will help speed up things like application launching and file searching.
