FileHippo is a pretty solid repository of freeware and shareware apps to be found for Windows and Mac. On the Windows side, you can find updates to third-party utilites by running this utility, which replaces its old Update Checker. It compares what's available on against what's installed on the PC and helps download the latest version (via, of course).
What if there were a worldwide group of talented ethical programmers voluntarily committed to the idea of writing and sharing software with each other and with anyone else who agreed to share alike? What if anyone could be a part of and benefit from this community even without being a computer expert or knowing anything about programming? We wouldn’t have to worry about getting caught copying a useful program for our friends—because we wouldn’t be doing anything wrong.
Distribution of source code. One of the problems with most proprietary software is that you can't fix bugs or customize it since the source code is not available. Also, the company may decide to stop supporting the hardware you use. Many free licenses force the distribution of the source code. This protects the user by allowing them to customize the software for their needs.
With mobile apps and a Google Chrome browser extension—and that's it—Chrome Remote Desktop more than rivals even TeamViewer for providing plenty of remote access between systems (you can't use it to control a smartphone or tablet, however, only PCs). You can connect to all your computers and devices that are on the same Google account, or get a code from others for a true remote session. You don't even have to have the browser running to get access to the PC. What's lacking is file transfer between systems, but you can get around that using Google Drive.

Copyleft licenses, with the GNU General Public License being the most prominent: the author retains copyright and permits redistribution under the restriction that all such redistribution is licensed under the same license. Additions and modifications by others must also be licensed under the same "copyleft" license whenever they are distributed with part of the original licensed product. This is also known as a viral, protective, or reciprocal license. Due to the restriction on distribution not everyone considers this type of license to be free.[35][36]
Eventually in this life, you're going to run into an archive file—a single file with multiple files stored (and compressed) inside it. They have different extensions, from RAR to ZIP to 7z and many more, and sometimes the program to open them costs you. Not 7-Zip. It opens all of those and more, and allows creation of new archives. It'll even encrypt the contents for safety. It's entirely open source.
From the 1950s up until the early 1970s, it was normal for computer users to have the software freedoms associated with free software, which was typically public domain software.[11] Software was commonly shared by individuals who used computers and by hardware manufacturers who welcomed the fact that people were making software that made their hardware useful. Organizations of users and suppliers, for example, SHARE, were formed to facilitate exchange of software. As software was often written in an interpreted language such as BASIC, the source code was distributed to use these programs. Software was also shared and distributed as printed source code (Type-in program) in computer magazines (like Creative Computing, SoftSide, Compute!, Byte etc) and books, like the bestseller BASIC Computer Games.[25] By the early 1970s, the picture changed: software costs were dramatically increasing, a growing software industry was competing with the hardware manufacturer's bundled software products (free in that the cost was included in the hardware cost), leased machines required software support while providing no revenue for software, and some customers able to better meet their own needs did not want the costs of "free" software bundled with hardware product costs. In United States vs. IBM, filed January 17, 1969, the government charged that bundled software was anti-competitive.[26] While some software might always be free, there would henceforth be a growing amount of software produced primarily for sale. In the 1970s and early 1980s, the software industry began using technical measures (such as only distributing binary copies of computer programs) to prevent computer users from being able to study or adapt the software applications as they saw fit. In 1980, copyright law was extended to computer programs.
But you can seriously amplify your lead generation efforts with the help of lead generation and lead management software. This type of lead management software helps you automate the process, by helping you schedule your social media posts, manage your content system, and work to grab information from potential candidates to help transfer incoming leads into the sales conversion process. Sales lead software can help you create a seamless and effective system to help you generate and convert more incoming sales leads.

With 10GB of free online storage, Box's Personal service now is one of the more robust free offerings. Box also limits file sizes to 250MB each. It does more than sync and have online access; it also offers tools for commenting on or editing documents (it won't replace an office suite like Google Drive, which you'll find below in Office Suites, though it could just as easily go in this category).

It's not super popular in the US and not even our favorite messaging app, but you can't ignore the 800-pound messaging gorilla that is WhatsApp—since it was purchased by Facebook for almost $20 billion and it has over a billion users worldwide. It offers end-to-end encryption, has animated GIF support, group chat for up to 256 people, document sharing, voice and video calls, one-tap voice messages, and a Web-based interface you access by scanning a QR code with the app on your mobile device. It recently added macOS and Windows desktop versions.

Free software is generally available at no cost and can result in permanently lower TCO costs compared to proprietary software.[68] With free software, businesses can fit software to their specific needs by changing the software themselves or by hiring programmers to modify it for them. Free software often has no warranty, and more importantly, generally does not assign legal liability to anyone. However, warranties are permitted between any two parties upon the condition of the software and its usage. Such an agreement is made separately from the free software license.
Commenting on Websites: Sites like Huffington Post, Entrepreneur and Forbes all rely on social media sign-ins. This means when you comment on these sites; you are logged into another site and posting as that profile. You can find the hottest articles, read the comments and connect with the commenters on their respective social media profiles. It’s one of the easiest ways to find leads. 
Up to three people on their PCs can use the browser to video chat and even share screens, all without fees or any setup other than sharing a URL. Sign up for an account or sign in with your Google or Facebook accounts, and you can claim a regular-to-use meeting "room" online. Because it's Web based, it works for Linux, Mac, or Windows, even on a Chromebook.
The expansion of online marketing with regards to promotional giveaways has facilitated the rise of "Freebie sites" that seek to aggregate all promotional free sample offers in one place. These sites will often compile free product samples from all over the World Wide Web and categorize them by type. Some product sample offers may require consumers to complete a survey or refer a friend in order to qualify for the freebies. When all requirements are fulfilled, the product samples are shipped to the consumer. Some sample products might be digital goods, where sample might be closely related to a product trial.
