Avoid data copying from your computer (USB Write protected)

In order to avoid copying of any type of data from your computer you need to make the write policies of your system to be protected.This can be done by adding a small entry to the Windows registry which acts as a switch that can be enabled to make use of the write protection or disabled to allow write access. 

 Just follow these steps:

• Open the Registry Editor (Open the “Run” dialog box, type regedit and hit “Enter”). 
• Navigate to the following Registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\ 

• Create a New Key named as StorageDevicePolicies. To do this right-click on Control, and click on New->Key and name it as StorageDevicePolicies. 
• Now right-click on  StorageDevicePolicies and create a New->DWORD (32-bit) Value and name it as WriteProtect. 

• Double-click on WriteProtect and set the Value data to 1.

Now the write-protection for USB drives is enabled on your computer (no restart required) and thus it would not be possible for anyone or any program to add/delete the contents from your USB flash drive. Any attempt to copy or download the files onto the USB drive will result in the above error message being displayed.
