PCMag's top pick for software to take control of other computers is TeamViewer. Almost everything you need is free: desktop sharing, file transfers, even chat with remote users. And the setup couldn't be easier. Take control of a PC over a Web connection and a Chrome browser (even in ChromeOS) with the TeamViewer extension. There is also a Windows app in the Microsoft Store and optional downloads to make installing TeamViewer on multiple PCs even easier—though it's only free for personal use.
Freeflys: Another strong contender in the freebies space, Freeflys has appeared on NBC’s Today Show, The Doctors, Fox News and a handful of other media outlets. Similar to most of these sites, Freeflys utilizes email alerts to tell users about free-sample offers as they happen. The site also allows you to search for a specific product with the handy search bar.
