There is no interface setting to turn off AutoRun completely. Instead, you have to edit the Windows Registry.

1. In the Search field, enter regedit, and select regedit.exe to open the Registry Editor.
2. Go to the key:  HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionPoliciesExplorer
3. If the entry NoDriveTypeAutoRun does not appear, create a new DWORD value by right-clicking in the right pane to access the context menu and selecting New DWORD (32-bit) Value.
4. Name the DWORD NoDriveTypeAutoRun, and set its value to one of the following:

• FF – to disable AutoRun on all drives
• 20 – to disable AutoRun on CD-ROM drives
• 4 – to disable AutoRun on removable drives
• 8 – to disable AutoRun on fixed drives
• 10 – to disable AutoRun on network drives
• 40 – to disable AutoRun on RAM disks
• 1 – to disable AutoRun on unknown drives

To turn AutoRun back on in the future, just delete the NoDriveTypeAutoRun value.
