Recently I’ve seen people having issues with certain devices attached via USB to their thinking machines… Issues that included, Spyware, Malware, Viruses.. ugh, many more.. Wouldn’t it be good to disable these unwanted creepy devices when on a shared/public windows  machines? Ok, follow these steps & get yourself a bit secured.

This can be implemented on your local Windows Machine or on the Windows Dedicated servers, please make sure to backup the Windows registry before following these steps. As making incorrect changes in Windows registry can make the system unbootable.

Search for the following keys in your registry to disable each of them respectively or as per your requirement.


Notice the value ‘Start‘, this should be 3 by default [3 = enabled]. Switch this value to 4 [4 = disabled], and USB storage devices are disabled. To re-enable the device switch this value to 3.
