Over time, our computers pile up more and more files and apps that, if left unchecked, can seriously undermine the experience. That applies to the Windows 11 context menu, too, as more and more apps register items that appear on it. These items are registered as shell extensions, and adding more of them means that the menu takes that much longer to load all of its content. If you have a lot of apps that create context menu entries, it gets to the point where the menu is slow to open, or it might even cause crashes and other problems.
