Posted by Usb drives are the most common and easy method of transferring data from one location to another.They include pen drives, removable hard disks etc….But if you want your system to be write protected so that no one can copy anything from your system with out your permission by blocking your usb ports.There is simple registry hack to do this trick. Don’t worry you don’t need to have any advanced registry knowledge for doing this trick .Just exactly follow my instructions.
Ok now we can start our trick,
1. First thing you have to do is to open run ( window + r ) and type regedit
2. Now browse to the following section from your registry window
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control
3. Make sure that you are in above specified path, then right click and add a new key and enter
“StorageDevicePolicies” without quotes.
4. If you succesfully completed step 3, then you can see StorageDevicePolicies on the right side panel. Ok now right click on that and add a new DWORD VALUE . and add its value as 1 (one)
Restart your computer to take effect.
Thats it you are done.Now all the USB Ports in your system is protected and no one can copy anything through usb.
