There may be many reasons why Windows Explorer will fail when processing a file or folder and the Not Responding message will appear - The computer will be in a stagnant state, delaying operations.
You can wait for Windows until the Not Responding runs out, but the best solution might be to restart Windows Explorer .
Actually quite simple, I will show you how to restart Windows Explorer:
For Windows XP, Vista and Windows 7
1. Open Task Manager : either directly by pressing Ctrl + Shift + Esc or by pressing Ctrl + Alt + Del and then open Task Manager .
Another way to do this is to right click on the Taskbar and select Task Manager .
2. Click the Processes tab .
3 . Find the explorer.exe process and click End Process .
4. To reopen it, click File> New Task (or open Run) , type explorer.exe and then click OK .
For Windows 8 and 8.1
What's new in Windows 8 is that the new Task Manager interface is more intuitive, realistic, and has more functions. Attached to it is an easier way to restart Windows Explorer.
1. Open Task Manager : either directly by pressing Ctrl + Shift + Esc or by pressing Ctrl + Alt + Delete and then select Task Manager.
2. In Processes tab , locate Windows Explorer (Usually in Apps group or Windows Processes). When opening the Task Manager interface for the first time the interface will collapse, click More details - Add details at the bottom
3. Click on it and you will notice that the Restart button is located in the lower right corner instead of the End Task button. This allows you to turn off the process and automatically restart immediately, without taking an extra step to turn processes back on Windows 7 and earlier.
Conclude
So when Windows Explorer is ignored - Not Responding. No response, instead of waiting, or restarting. You just need to restart Windows Explorer.
