Key Points
Introduction: Explains why allowing AutoRun/AutoPlay increases exposure to malware delivered through USB drives, removable media, and mapped/network shares, and why disabling it is recommended as a Windows hardening step.
Quick setup: Shows how to detect the AutoRun is enabled (or AutoPlay is not restricted) misconfiguration in Vulnerability Manager Plus and provides the exact Group Policy steps to disable AutoRun (and optionally AutoPlay) consistently across managed endpoints.
Frequently Asked Questions: Covers practical questions about AutoRun/AutoPlay hardening, including what they do, why attackers abuse them, the impact on users and legacy workflows, which media types are affected (USB/CD/DVD/network), how to verify the effective setting on endpoints, recommended enterprise policy combinations, and what to do after enforcing the policy.
AutoRun (and the related AutoPlay behavior) is a Windows feature that can automatically launch content when removable media such as USB drives, CDs, or external storage is inserted. While it was designed for convenience, it can also be abused to trigger unwanted programs or scripts when a device is plugged in.
If your environment does not require AutoRun for legacy workflows, disabling it is a recommended OS hardening step. It helps reduce the risk of malware spreading through removable media and limits “plug-and-run” execution paths, especially on roaming endpoints that may connect to less trusted networks.
If you still need AutoPlay prompts for user convenience, you can disable AutoRun (automatic execution) while selectively controlling AutoPlay behavior. In enterprise environments, enforcing these settings using Group Policy helps ensure consistent protection across all managed devices.
You can detect this misconfiguration (Autorun commands are allowed to run without user intervention) using Vulnerability Manager Plus. This misconfiguration comes under the category of OS Security Hardening and has a Critical severity.
To detect this misconfiguration:
To remediate the misconfiguration using Group Policy:
This remediation does not require reboot.
Scheduling reports keeps teams informed without needing to log in manually.

AutoRun is a Windows feature that can automatically run commands defined on removable media (for example, through an autorun configuration) when the media is inserted.
AutoPlay controls what Windows prompts or actions to show when you connect media (like photos, videos, or audio). AutoRun is specifically about automatically executing commands. Disabling AutoRun reduces automatic execution risk, while AutoPlay usually affects prompts and user choice.
Attackers can abuse AutoRun-style behaviors to trigger malicious code from removable media. Disabling it reduces “plug-and-run” execution paths and helps prevent malware from launching automatically when a device is connected.
Depending on Windows version and policy configuration, these settings can affect removable drives (USB/external storage) and optical media (CD/DVD). Some organizations also harden related behaviors for mapped/network locations based on their risk model.
No. Disabling AutoRun does not block USB storage access. It only prevents automatic execution of autorun commands. Users can still open the drive and run approved installers manually if needed.
Most users will notice little to no impact. The main change is that software or media will not launch automatically when inserted. In environments that rely on legacy media-based installers, users may need to start setups manually.
You can verify the effective configuration by checking the applied Group Policy on the device (for example, via policy results) and confirming the AutoRun policy is set to Do not execute any autorun commands.
A common hardening approach is enabling the policy Set the default behavior for AutoRun and selecting Do not execute any autorun commands to prevent automatic execution across endpoints.
Many organizations disable or restrict AutoPlay to reduce risky prompts and user-driven execution paths. At minimum, disabling AutoRun is strongly recommended; whether to also disable AutoPlay depends on usability needs and policy requirements.
After linking the GPO, ensure devices receive the update (either through the normal refresh cycle or a forced update). Then confirm compliance in your management console, and document the change as part of your Windows hardening baseline.
