How to unlock Pen drive if it is locked at office or college computer

Generally in colleges and Organisations USB drives are locked. It is sometimes irritating when we want to copy some important data from that computer but computer refuses to recognize it and says Found new hardware, USB Mass Storage Device, please install drivers for it. I got a similar problem in my coaching centre. I Google it and find the solution at Troublefixers. It defines two methods to tackle this error. But you should have administrator rights to use these methods. To have administrator rights check this post Cracking Administrator Account

1)Disabling USB Ports from Device Manager

i) Go to Start > Run, in run prompt type “devmgmt.msc” and press enter.
ii) Go to Universal Serial bus Controller. See if there are any red colored cross? If yes, right click and enable those USB Ports.

Now try and use the pen drive.

2) correct Registry Value for USB Mass Storage device

i) Go to Start > Run , type “regedit” and press enter.ii) Navigate to the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR
