I have the same, or similar, issue. It is not expected and showed up around the 
9419 build release. Currently have no ETA of a fix.

Thanks,
John

Subject: [WiX-users] Win8.1 + DIFx problem...

I have a device driver install which is working just fine.  However, I'm 
getting different behavior on Win8.1 compared to the previous releases of 
Windows (Vista, Win7, Win8).

On the previous releases of Windows, removing the MSI package from the Control 
Panel->Programs and Features results in the device driver being removed from 
the driver store.  It also results in the replacement of the active drivers 
instances with the nul device driver.  I don't know if this is default DIFx 
behavior or something that WiX is asking DIFx to do for me.

On Win8.1, the driver package is removed from the driver store but the driver 
instances are not being changed in any way.

Is this expected behavior?

I'll do some digging and see if DIFx is installing the nul driver based on the 
DIFx action or if WiX is doing it just to be kind (and yes, it is kind of WiX).

Best regards,
Robert.
