Uninstalling an app on your Mac isn't as straightforward as you would think. When you drag and drop an app into the Trash, then empty it, the main app itself may be gone, but many associated files and folders are left behind. So how do you get rid of them? There are a couple of ways.

Not all batteries are created equal, but one thing's for sure—they all lose capacity over time. Thankfully, the advanced lithium-ion batteries in your MacBook and iPhone are meant to last for several years before they begin to lose their overall charge capacity.

Returning your device to stock, whether it is because you need to sell it or just want to receive OTAs again, is not always a simple process. Since HTC has released countless variations of both the M7 and M8 HTC One, it can be a pain in the ass finding the right files and tools to get your phone back to stock settings.

In modern versions of Windows, Microsoft made quite a few changes to Windows Explorer, the first of which is a new name—File Explorer. Another huge change that most will notice is that File Explorer now has a new look sporting the Ribbon interface.

Microsoft has been listening to user feedback, and they've finally done something about one of the most common minor gripes with Windows 10. As of build 10525, there's now an option for changing the title bar color in apps, so you won't have to use this old workaround to personalize your window coloring anymore.

It's official: The next version of Android will be code-named "Marshmallow," and we're getting a whole number bump to version 6.0. Lots of exciting new changes are coming to the world's most popular operating system, including a "Now on Tap" feature that will give you relevant information about any screen at the press of a button.

While most of your iPhone's features are intuitive or well-covered across the web, there are some features hidden deep within iOS that you probably never even knew about. (These could also apply to an iPad or iPod touch.)

Flashing people in an oversized trench coat is both old-fashioned and exhausting (and also very illegal). But like the evolution from school-yard bullying to cyber-bullying, it seems as if the new trend is "cyber-flashing" (it's even has an official hashtag). In the U.K., police are now investigating what they are calling the first cyber-flashing case.

In a bit of a strange decision, Microsoft has made it to where some users don't have a choice in the matter of applying failed automatic updates. When a Windows or driver update comes your way and fails to apply for any reason, your computer will continue to attempt applying the broken update at seemingly random intervals. The Pro and Enterprise editions of Windows 10 will allow you to delay or stop updates altogether when something like this happens, but the Home edition has no such setting.

One of the biggest gripes I initially had with the LG G3 was the lack of options for the Shortcut keys, which are the volume keys that allow you to launch the camera or the QuickMemo+ app directly from the lock screen. I never use QuickMemo+, so having it as a shortcut was a complete waste of functionality.

You can beef up the security on your Mac all you want, but all the firewalls and antivirus apps in the world mean nothing when that can of soda tips over on your Macbook, destroying your laptop and all its data forever.

Apple just released the latest developer preview of OS X 10.11 El Capitan, currently in its sixth beta. While this latest build mostly deals with tiny improvements and bug fixes, it also includes a brand new breathtaking wallpaper of the El Capitan rock formation in Yosemite National Park.

One of the highest rated posts on Spotify's own community forum is titled "Add support for Google Chromecast," a clear indicator of not only how much this feature is desired, but also of Spotify's lack of care for it. Remaining consistent with statements made in the past, Spotify is firm in their decision to not pursue Chromecast support at this time—or maybe ever—thanks to a deal with Sonos and Spotify Connect.

The increased sophistication of smartphones and apps have allowed us the luxury to never leave our homes. Everything from coffee to food to dry cleaning can be delivered straight to your door without ever leaving your couch, which can can be a godsend during the winter months when you'd rather not risk leaving your warm bed. But during the summer, you gotta ditch the comforter and go enjoy outdoors.

Windows 10 makes it a cinch to change the lock screen background: simply go to Setting -> Personalization -> Lock screen, then change the background to whatever you'd like.

The day has finally come, and after quite a bit of hype and buildup, Windows 10 is now officially available. The update itself is on a staged rollout, which means it will be slowly becoming available to users over the coming weeks and months, so don't panic if you haven't already received an update notification. Besides, you have until July 29th, 2016 to download your free copy of Windows 10 if you're eligible, so there's plenty of time to get your ducks in a row.

Windows 8 had an easy "Set for monitor" option that allowed you to use different wallpapers on a multi-monitor setup—an option that is seemingly absent from Windows 10. But with a quick command, you can easily restore this function on Windows 10, so that it behaves like Windows 8.

The Start menu is finally back in Windows 10, but a lot has changed since we last saw it in Windows 7. From a visual standpoint, the first difference you'll notice is the addition of live tiles, which occupy the right half of the Start menu and provide quick information from your "Universal" Windows apps.

Whether you're just getting your first Android, or are already on your fifth annual cycle of picking up the latest flagship, there is always the question of what to do after booting up your device for the first time.

Hidden deep in WhatsApp's emoji database is a middle finger emoji, and there's a really easy way to use it. Much like Spock's "live long and proper" Vulcan salute, this one can be used simply by copying and pasting the emoji from our tweet.
