How to Enable Disable USB mass storage device


Friends In your college's net lab you may want to block USB mass storage device to disallow the unauthorized use of pen drives or may want to unblock USB mass storage device to get access. Well friends, this can be done by a simple registry tweak.But before doing so, I recommend taking a backup of the registry because playing with registry can be harmful for your OS. 

When you have backup the key

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR proceed further.

To disable access 

REGEDIT4

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR]
“Start”=dword:00000004


To enable access

REGEDIT4

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR]
“Start”=dword:00000003

Copy the required code to a text file and save it as *.reg file. Just open that file and information will be added to the registry.
