This sometimes happen when a certain app takes over icons cache in Windows, such as some antivirus software. Here’s how to reset that:
Run PowerShell or CMD as Administrator:
function fixWindowsIcons{
Stop-Process -ProcessName explorer -force
remove-item "$env:localappdata\IconCache.db" -force
remove-item "$env:localappdata\Microsoft\Windows\Explorer\iconcache*" -force
$keyname='IconHandler'
$iconHandlerKey="REGISTRY::HKLM\SOFTWARE\Classes\lnkfile\shellex\$keyname"
$iconHandlerExpectedValue='{00021401-0000-0000-C000-000000000046}'
$defaultIconHandler=(get-itemproperty $iconHandlerKey).'(default)'
if($iconHandlerExpectedValue -ne $defaultIconHandler){
New-ItemProperty -path $iconHandlerKey -name $keyname -value $iconHandlerExpectedValue
}
start-process -processName explorer.exe
write-warning 'Please restart the computer to finish resetting Windows Icons cache...'
}
fixWindowsIcons
