Disable USB Storage Access for other Computer Users

Nowadays 90% viruses and other malicious programs are distributing through Pen drivers and other equipments which are use USB ports.

So this article would be useful those who have headache about restricting their USB ports using by other parties without knowing.

So in here I discussed small registry edit which can use for disable USB storage access for a certain group of users. USB port access disabling and re-enabling both can do by simply changing the value of a registry key.

Disable access to USB port in windows XP and 2000
  • Open run (Go to start and Run)
  • In the box type “regedit” to open registry editor.
  • Locate the following path.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\UsbStor
  • In the right side window double click Start.
  • In the Value data box type 4 click Hexadecimal (if not already selected) and click OK.
  • Exit Registry Editor.

Re-enable the disabled port
  • Open Regedit
  • Locate the following registry path:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\UsbStor
  • In the right pane, double-click Start.
  • In the Value data box, type 3 and make sure to check Hexadecimal and then click OK.
  • Quit Registry Editor and restart the computer.
Only disabling the USB port access we cannot assure that the computer will not affect by viruses. This approach is for block unauthorized USB accesses to your computer. For a complete solution you'll need to refer our previous articles about dealing with viruses.
