You may want to block USB mass storage device to disallow the unauthorized use of pendrives or you may want to unblock USB mass storage device to get access (most of the case in college’s net lab). Well, this can be done by a simple registry tweak. Before doing so, I recommend taking a backup of the regustry because playing with registry can be harmful for your OS. Read (How to backup your windows registry). 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.

THis tip will come in handy as lots of pen drive viruses are spreading.
@Madhur
Yeah! Many registry trick comes handy. I wish I can remember them all so that they can be recalled anytime.
Thanks for the info. I was aware of this solution but after my latest reboot, i receive the following message “Cannot edit Start: Error writing the value’s new contents”. This started happening after the latest reboot of my WORK desktop and I am fairly certain some type of script was applied to preclude me from editting the registry file. Any ideas on another workaround?
