System - Disable Enable with IO

Note This content applies to the Windows Logo Kit (WLK). For the latest information using the new Windows Hardware Certification Kit (HCK), see Windows HCK User's Guide on the Windows Hardware Dev Center.

Type: Automated Test


The System - Disable Enable with IO job disables and then enables every disableable device in the system. Additionally, this job tries to ensure that the devices are still functional after the changes in state through SimpleIO stress testing.

Note This test applies to both client and server.


The System - Disable Enable With IO job is the "System" version of the Disable_Enable_With_IO automated scenario.

This job directs the underlying scenario to target all possible devices. Additionally, the underlying scenario can target only disableable devices. A disableable device is a device that has the Disable option available in Windows Device Manager and that is not the "LegacyDriver" class.

Run Time: 2 Hours

System Restart Required: No

Supported operating systems for Logo or Signature testing:

  • Windows 7

Running System - Disable Enable with IO

To run this job, do the following:

  • Ensure that your machine pool has been configured for the proper logo program.

  • Create a system submission (Logo) in the Device Console window.

  • Run the System - Disable Enable With IO Job from Device Console.


The underlying scenario was developed by using the new Microsoft Windows Device Testing Framework (WDTF). The Windows Driver Kit (WDK) contains extensive documentation for using and extending this framework in your own driver development process. For more information, search the WDK Help documentation for "Windows Device Testing Framework".

You may receive an error message similar to the following: "SimpleIOStress Failed! -> IcmpSendEcho() had too many consecutive timeouts. Win32=1214 - The format of the specified network name is invalid." This failure can be caused by network latency, which can be improved by trying one or more of the following steps:

  • Disable DHCP and use static IP addressing.

  • Place a router or switch directly between the controller and client.

  • For redundant network paths, add an additional NIC connected to the network.
