In this article, I will show you 4 ways you can remove the Activate Windows watermark on your Windows 10 PC. This happened to me when I was using freeCodeCamp for my first round of 100DaysOfCode. If this is the case, you can remove the watermark because it could have a negative effect on visual hierarchy and might be embarrassing if you're taking screenshots or recording your desktop. You will also be unable to install Microsoft Office. This keeps you from being able to personalize your desktop or get updates for Windows Defender – now Windows Security.
This message gets displayed when you use a Windows OS that has an invalid or expired license. I guess they gave it a z-index of infinity. If you're a Windows user, you might have seen the 'Activate Windows' message that displays over every other thing – including your cursor.
