How can I do not drag files under Win8?

  
I suddenly encountered a situation where I could not drag files under Win8. I thought it was a mouse driver or a setup problem.
Reinstalling the mouse driver and modifying the mouse settings could not solve the problem.
A search on the Internet found that many people have had the same problems as me.
At the same time, the solution is given and recorded as a memo.
Workaround 1:
Jump to the desktop immediately, press the ESC button twice, you can drag the file.
Solution 2:
Restart Win8 system.
