The Windows AutoRun feature is turned on by default on most Windows versions, allowing programs to run from an external device as soon as it is attached to a computer.

Because malware can exploit the AutoRun feature — spreading its unfortunate payload from your external device to your PC — many users choose to disable it. 

AutoPlay is a Windows feature that is part of AutoRun. It prompts the user to play music and videos or display pictures. AutoRun, on the other hand, is a broader setting that controls the actions to take when a USB drive or CD/DVD is inserted into a drive on your computer.

Disabling AutoRun in Windows

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

  1. Press Win+R and type regedit to launch the Registry Editor. You'll have to confirm elevated privileges to modify registry settings.

  2. Go to the key:   

    HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer
    Windows registry editor

  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
    Windows registry

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

Disabling AutoPlay is easy, but the process depends on your operating system.
