Normally when we share a local resource on the network a hand icon is placed under the item to show it is shared.
You can remove the icon With this simple Registry Tweak
Open your registry (open run type regedit)
go to this path : HKEY_CLASSES_ROOT\Network\SharingHandler
delete the default value that is "ntshrui.dll"
Restart Windows for the changes to take effect.
You can also Download readymade reg files to do this by simply clicking on it.
