In trying to access AppData for the main user I managed to hide the Users folder so none of it shows at all (!!???). Then tried to unhide it by selecting Show Hidden Files and Folders, View option, but with no success. My other, older HDD running Vista clearly shows the Win7 Users folder and all its content. Also (as a result no doubt) now the Libraries and Favorites folders don't show their contents either. Is there a fix that doesn't call for a restore point (doesn't work) or restoring a backup or image file (I don't have either). Help!!!!!!!!!!!
