About the Win7 icon missing, abnormal display repair method

Windows7 after installing some software, the application icon does not display properly, it will only show a file, no icon or chart display error. If you double-click, you can also open the application. It is common to observe that this problem occurs after adjusting the disk drive letter from "Management"-"Disk Management". Of course, it does not rule out other possibilities for this problem. As the standard:
<ignore_js_op>--------->>> <ignore_js_op>

The solution is as follows:

method One: Manually delete the iconcache.db file
Boot press F8 boot into safe mode, after entering the system, search the Iconcache.db file of each disk, and then delete it. It's OK to restart your computer! This file is slow, and if unsuccessful, use the next method.

method Two: Establish a clear Windows7 icon cache file
Copy the characters in the dashed line below into Notepad or a text editor, save as "fix icon. bat" and double click to run.

REM Close Windows Shell Explorer
taskkill/f/im Explorer.exe
REM Cleanup System icon Cache database
Attrib-h-s-r "%userprofile%\appdata\local\iconcache.db"
del/f "%userprofile%\appdata\local\iconcache.db"
attrib/s/d-h-s-r "%userprofile%\appdata\local\microsoft\windows\explorer\*"
del/f "%userprofile%\appdata\local\microsoft\windows\explorer\thumbcache_32.db"
del/f "%userprofile%\appdata\local\microsoft\windows\explorer\thumbcache_96.db"
del/f "%userprofile%\appdata\local\microsoft\windows\explorer\thumbcache_102.db"
del/f "%userprofile%\appdata\local\microsoft\windows\explorer\thumbcache_256.db"
del/f "%userprofile%\appdata\local\microsoft\windows\explorer\thumbcache_1024.db"
del/f "%userprofile%\appdata\local\microsoft\windows\explorer\thumbcache_idx.db"
del/f "%userprofile%\appdata\local\microsoft\windows\explorer\thumbcache_sr.db"
REM Cleaning system Tray memory icon
Echo y reg delete "hkey_classes_root\local settings\software\microsoft\windows\currentversion\traynotify"/V IconStreams
Echo y reg delete "hkey_classes_root\local settings\software\microsoft\windows\currentversion\traynotify"/V PastIconsStream
rem Restart Windows Shell Explorer
Start explorer

Method Three:
1: Open Task Manager (taskbar right, start Task Manager), end the running Explorer.exe process (Explorer is the desktop process, after shutting down, you will find that your desktop is gone, do not matter, solve the problem need)
2: Click on New Task, enter "CMD" in open space, execute the following command:
cd/d%userprofile%\appdata\local (carriage return)
DEL iconcache.db/a (carriage return)
Exit (Enter)
Then rerun "Explorer.exe", (Click on "File" of Task Manager--New task "Run" and enter Explorer.) ）
Principle: Iconcache.db file as an icon property file, due to some kind of operation, resulting in file corruption, deleted, the system will be automatically rebuilt. The icon will then return to normal.

The third way I use it immediately.
