I'm having issues where a mapped network drive (using the map a network drive link in win7 my computer) where during the day it will duplicate itself and use up all driver letters and all these duplicates cannot be opened or used

Hi, Did this issue occur to all mapped network drives? First, to eliminate the software conflicts, please boot into Clean Boot mode to see what the result is. You could modify the registry value of mapped drivers to see if this issue persists: Note: please backup the registry before performing the any modification. HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Explorer \ Map Network Drive MRU In the registry value, you could clear the duplicated drive path. If this issue persists, please try another user account for test. Hope it helps.
