Fixed favorites in Win7 Explorer could not be expanded

Today, the author's windows 7 encountered a small problem, the resource manager's "Favorites" can not be expanded, but "library" and "computer" can be. But click on "Favorites" to get to the "Favorites" folder, the shortcuts inside are not lost. I tried to right click on "Favorites" and select "Restore Favorites". The link has no effect. In other words, some reasons have caused Windows 7 Explorer's "Favorites" to fail.
I haven't found the answer for a long time. I used English as a keyword to search. After several links and jumped, I finally found the answer.
