Fix cannot Rebuild Corrupt IconCache.db in Windows 10

After I installed a transparent file in Windows 10 anniversary update and re-login to system, all icons and thumbnails had disappeared on my Desktop and File Explorer. All icons of installed apps became blank and didn’t refresh correctly, as well as I could not right click on item to access its properties. But their name show and I am able to run it. How can I rebuild icon cache?

Windows 10 has a special icon cache database file called IconCache.db to make system draw the icons faster. If IconCache.db is corrupted, the icons and thumbnails will be blank and do not display correctly. To resolve the problem, you need to delete it to clear the icon and thumbnail cache and the new cache database will be created.
* Press Ctrl + Alt + Delete keys to open Task Manager. Or right click on the taskbar and select Task Manager
* Under process tab, right-click on the Windows Explorer process select End process.
* Select Run new task from the File menu at top, type cmd.exe, check “Create this task with administrative privileges” box, and click OK button.
* In the elevated command prompt, type the commands below one after the other and hit Enter to execute it:

cd /d %userprofile%\AppData\Local\Microsoft\Windows\Explorer
attrib –h iconcache_*.db
del iconcache_*.db
cd /d %userprofile%\AppData\Local\Microsoft\Windows\Explorer 
attrib –h thumbcache_*.db 
del thumbcache_*.db 
start explorer

If the above method is not working, you need to copy IconCache.db from other Windows 10 PC to a thumb drive, then implante this file where it belongs (C:\Users\%username%\AppData\Local\). The IconCache.db is a hidden file, so you should set the folder options to show Hidden System Files in File Explorer. once you’ve done, all icons pop back again.
