When you right-click an item (such as a file, a folder, or a network connection) in Windows Explorer or in My Computer, other programs may temporarily stop performing a task. For example, a video that is being played in Microsoft Windows Media Player may temporarily stop being played.
If you start Windows Task Manager, you may notice on the Processes tab that the Explorer.exe process is using a lot (or 100 percent) of the CPU resources. To start Windows Task Manager, right-click an empty area on the taskbar, and then click Task Manager.
This problem occurs if the following settings are turned on, and you right-click an item to select that item:
If these settings are turned on, information about the selected item is shown in the Tasks pane in Windows Explorer by using an animation. If you open a shortcut menu (the menu that appears when you right-click an item) while this animation is occurring, the animation may not be able to finish (and may use a lot of the CPU resources) until you close the shortcut menu.
To work around this problem, select the item before you right-click it. To select an item, either click the item or rest the mouse pointer on the item.
You can avoid this problem by turning off either of the settings that are listed in the "Cause" section of this article. To do this, use one of the following methods:
Method 1: Turn Off the "Fade or Slide Menus into View" Visual Effect
Method 2: Use Classic Windows Folders
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
