To back up your data, drag (or copy and paste) everything you want to keep into an external drive of your choice. But, again, this is simply good practice and regularly backing up your information is a useful habit to get into.

Having said that, we still recommend backing up any files and data that you want to keep. As part of its quick and easy reset-and-start-again process, Windows 10 gives you the option to save your personal files before it goes ahead with the reinstallation. The good news is that if you're reinstalling Windows 10 onto a working computer that you can still use to make changes, there's no reason why you should lose any personal data at all. If you've picked up a serious virus or run into some buggy software that won't allow you to do anything, wiping the disk and starting again might be the only alternative to giving up on perfect hardware.

This is a somewhat extreme way of spring cleaning your hard drive, but it's certainly effective. If your computer's performance has taken a nosedive recently, reinstalling Windows 10 - also known as a PC reset - might be the perfect solution.
