Hi,

After we install and uninstall our (InstallShield) driver package on Windows
Vista (32 bit), we see a leftover file:
C:\Windows\system32\drivers\Msft_Kernel_<our_driver_name>_01007.Wdf

Does anyone know the reason for this file, or what it's for, why it is not
removed by uninstalling our driver(s)?

Our driver package contains other drivers as well, but only our WDF driver
seems to cause this leftover file.


Any comments appreciated,

/ Hannes.

this is called a marker file. it is there to indicate that a KMDF driver
was once installed. this is used during online crash analysis (OCA) and
other system diagnostics. the file is empty and there is nothing to worry
about, it is supposed to remain after uninstall
