Here’s an annoyance that’s happened to me recently. My screenshots are automatically saving to OneDrive. While I do back up many documents and images to OneDrive automatically, most of the screenshots I take (and there are a lot of them) aren’t something I need to backup to keep. 

Here’s how to handle the issue. Righ-click on OneDrive in your system tray.

Choose Settings.

When this window opens, click on the Backup tab. Untick the box next to screenshots. This is also where you choose if you want to back up photos and videos.
