Disable Autorun/Autoplay

Windows' Autorun feature is turned on by default on most Windows versions, allowing programs to run from an external device as soon as they are attached to a computer.

Because malware can exploit the Autorun feature — spreading its unfortunate payload from your device to your PC — it has been somewhat polarizing, and many users choose to disable it. 

Note: AutoPlay is a Windows feature that is part of AutoRun.

It prompts the user to play music, 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 are inserted into a drive on your computer.

Disabling AutoRun

There is no interface setting to turn off autorun completely; instead, you need to edit the Windows Registry.

1. In the Search field, enter regedit, and select regedit.exe to open the Registry Editor.
2. Navigate to the key:  HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer
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 it 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.

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