Stickers in Windows 11 is a new feature that allows users to personalize their desktop with variously-themed stickers, similar to how people customize the lids of their laptops. To use stickers, users need to enable them in the Registry Editor or have to use a Windows 11 SE edition (Windows 11 SE is a different edition of Windows 11 made for students) and then access them from the Personalization settings or the desktop context menu. Stickers can be added, edited, deleted, resized, and repositioned on the desktop. Stickers are only available in Windows 11 22H2 build or newer, and may not work with slideshow backgrounds.
I have made a video in this topic so watch the video down below for more information.
