What should I do if the Win10 start menu does not open? Win10 start menu can not open solution

What should I do if the Win10 start menu does not open? After the official version of Win10 was installed, many of my friends said that the start menu sometimes could not be opened. This problem has always existed, the latest version of the performance has been slightly better, but occasionally will appear, the general restart can be restored. However, you can't always restart the system to play, it's a waste of time. In fact, this time only need to restart the "Desktop Window Manager" start menu to be able to recover.

Detailed steps:

First save the work at hand.

Right-click on the blank space of the taskbar, or press the shortcut key Ctrl+Shift+Esc to open the task manager.

Switch to the details mode. In the process, find the "Desktop Window Manager" (English system to find the Desktop Window Manager), right-click "End Task". At this time, a prompt window will pop up, check "Give up unsaved data and close", click "Close".

After the process is finished, the desktop window manager will restart automatically under normal circumstances, and the start menu will be available again. If the desktop window manager is not restored, click "File" - "Run New Task" in the task manager, enter dwm and press Enter.
