Disable USB drives

If we are using an Office PC, it'd be very difficult to disallow access to any of our colleagues and their USB drives, which might be thriving with viruses. It so happens that our flash drives are clean and those of others are full of viruses. Any way, there is no way to limit the access.

However, there is a way!

Open regedit and go to HKLM\System\CurrentControlSet\Services\USBStor.

Select the key 'Start'. Its value will be 3 by default. Change it to 4 and USB drives will be disabled. To enable them, change the value back to 3.

This works in Win XP. However, the source site says it will work on Win 2000 and 2003 as well.
