Now you want to view hidden files. Press the Alt key on your keyboard so your file menu will come up. Go to Tools > Folder Options. Under the View tab there is an option for "Show hidden files, folders, and drives." Now you should see a file named IconCache.db. Please delete that file. Now copy this text.
taskkill /F /IM explorer.exe
cd /d %userprofile%\AppData\Local
attrib –h IconCache.db
del IconCache.db
start explorer
Paste that into a text document and save the text document as fixIcons.bat . Now double click the bat file to run it. This will now fix your icons.
Good luck. Please comment if you have any questions. Thanks.
