Win7 EXE application icon lost How to do

Encountered a strange problem DW 5.5 found that the icon disappeared after installation, the shortcut became a thing without an icon. Very uncomfortable. Looking for it on the Internet is really a strong person, sharing the solution to everyone.
Restore at the command prompt by entering the following command.
button "WIN+R" Enter cmd
and enter the input separately:
taskkill /im explorer.exe /f
cd /d %userprofile%appdatalocal
del iconcache.db /a
start explorer.exe
exit
Looking at this code, it should be to delete the icon cache database, and then start
explorer.exe
my system is Win7 64 Ultimate, test success!!!
