Sometimes when you install a program in Windows, or when you apply a registry hack, you need to log out or restart Windows. However, the same thing can usually be accomplished by restarting the Windows Explorer (explorer.exe) process.
We have previously written about how to restart the explorer.exe process in Windows 7 and Vista. This article shows you how to use the new Task Manager in Windows 8 to easily restart the Windows Explorer process.
While on any screen in Windows 8, press Ctrl + Shift + Esc. If the Windows Task Manager displays like the following image, click More details to access the detailed interface.
Make sure the Processes tab is active. Notice that the standard End Task button is available in the lower, right corner of the dialog box, like in Windows 7.
Scroll down in the list of Processes until you find the Windows Explorer process. When you select the Windows Explorer process, the End Task button becomes a Restart button. Click Restart. The Windows Explorer process closes and restarts automatically.
To close the Task Manager, select Exit Task Manager from the File menu.
This is one of the more useful, time-saving changes made in Windows 8.
