If there's one keyboard shortcut that every Windows user should know, it's Ctrl + C. It lets you copy anything to your clipboard in an instant and makes moving text and images between apps a breeze.

But the shortcut does have a downside: sometimes it doesn't work. And when it doesn't, it can be hugely frustrating -- especially if you've just had a five-minute battle with your web browser to select exactly the right bit of text.

Alas, thanks to a new app called ClipboardNotifier, you don't need to worry anymore. You will always know whether your clipboard copying was successful.

ClipboardNotifier is entirely free to download and use. You can grab a copy from GitHub. (Sorry Mac and Linux users, this app is only available on Windows.)

The installation process is simple. Download the ZIP file to your computer and unzip it. The unzipped folder only contains two files: a DLL file and an EXE file. Double-click on the EXE file to launch the program.

Fire up the app. You can ignore the Windows SmartScreen warning. When the app is running, you'll see a small icon in your system tray.

Every time you successfully press Ctrl + C while the app is running, you'll see the app's icon pop up in the center of the lower part of your screen. You can see an example in the image below:

To close the app, right-click on the Taskbar icon and select Exit. Remember, you even can make the app run when your system boots if you wish.
