Disadvantages of Not Activating Windows 11

Without activating Windows 11, you may not apply the Dark Mode and can’t access Personalization settings. Plus, you will miss crucial Windows updates & bug fixes and have to tolerate the Activate Windows watermark on the screen. Also, you’ll get stuck with limited themes.

With an inactive Windows 11, you can’t change the colors and font. Also, you can’t change the lock screen wallpaper as you want. It’s like you can only do limited personalization, which is boring.

If you go to Settings, there are many things you can’t change. The Windows Start menu is an important feature from which you can access frequently used apps and perform several tasks. So, you can’t change minor settings in the Start menu from an inactive Windows.

The taskbar is a crucial part of Windows OS; you can pin or unpin any application. The pain part is you can’t customize the taskbar either. Additionally, you’ll get frequent notifications to activate your Windows which will annoy you greatly.

So, it is meaningless to keep working with Windows 11 if you can’t use its full features. You must activate it right away.
