Welcome to forums MaikeIS

Latest version is 4.4.1 build 2000 obtainable via liveupdates may need to set search for beta and stable builds.
Since you only specify latest obtainable in download page that wont be actual latest.

Update to that VERY latest and try again.

Also try selecting and or unselecting the settings as in screenshot.



Something you may want to look at is also have you customized or have a program that changes the windows Folders icons or if not resetting them to default via Control Panel> Folder Options>View tab and click reset folders



Im more inclined that you guys have some icon cache corruption or something that way inclined.

You can clear you icon cache by using this batch file /run as admin

@echo off
set iconcache=%localappdata%\IconCache.db

echo ************************************************************************************************
echo The Explorer process must be killed to delete the Icon DB.
echo ************************************************************************************************
echo.
echo ************************************************************************************************
echo Please SAVE ALL OPEN WORK before continuing.
echo ************************************************************************************************
echo.
pause
echo.
If exist "%iconcache%" goto delID
echo.
echo ************************************************************************************************
echo Icon DB has already been deleted. 
echo ************************************************************************************************
echo.
pause
exit /B

:delID
echo ***********************************************************************************************
echo Attempting to delete Icon DB...
echo ***********************************************************************************************
echo.
ie4uinit.exe -ClearIconCache
taskkill /IM explorer.exe /F 
del "%iconcache%" /A
echo.
echo ************************************************************************************************
echo Icon DB has been successfully deleted. Restarting your PC for rebuilding cache MAY be necessary.
echo ************************************************************************************************
echo.
echo ************************************************************************************************
echo You should be able to see new icons immediatly without PC restart.
echo ************************************************************************************************
echo.
start explorer.exe
pause
exit /B
