Consider OneDrive the most flexible and all-encompassing sync and back-up tool going. It's the official cloud storage for users of Microsoft Office and Windows 10 (it's built right into the OS). OneDrive throws in 5GB of free online storage; you earn extra by referring friends or backing up smartphone cameras. If you subscribe to Office 365 Home, that storage jumps up to 1TB.
The first of a few Piriform programs on this list, CCleaner—the first C is for Crap!—is one of the best, and pretty much essential for keeping a system going. What it does is simple: it cleans up extraneous files to keep a system running better. Get it and run it, regularly. It'll even delete some apps you didn't think you could get rid of—like those provided in Windows 10, whether you wanted them or not.

Imagine not having the hassle of Windows, but still being able to run (most) Windows programs? That's the goal with ReactOS, which builds on the old Windows NT architecture as an open source operating system. And it only takes a 150MB to install it, so it's small. You can grab it as a full installer, or make a LiveCD version that boots off a disc to give it a try.
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.
The best thing about some of these companies is that you don't have to "Like" them on Facebook, send messages on Twitter, or complete surveys. With the companies I've listed first, simply sign in, input your mailing information, and wait for the free sample to show up in your mail).
