In HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Mydriver I see an
entry called Tag.
I see this entry in many drivers.
what is that entry?????
I see random numbers each and evry time I install my driver.

Thanks in advance

"An optional key called Tag can be included in a device driver's registry.
The value of the Tag helps determine the loading order of the device drivers
within a group." : http://support.microsoft.com/kb/115486

Load order for non-PnP drivers within the load order group.

Hi,
My driver is of group "filter"
each and every time I install and uninstall my driver the tag value gets
incremented by 1.
number of drivers in filter group in gropuorderlist also gets incremented by
1 for each and every install and unistall.

when I checked the grouporderlist intially the filter group had one driver
in it.
After I installed my driver it became 2.
Now I uninstalled and installed my driver again.Now the number of drivers in
that filter group became 3.correspondingly my tag gets changed to 3.

where am I going wrong???
Is there any specific thing I need to dod in uninstallation so that the
number of drivers in the filter group should not get incremented like the
above..

Thanks in advance

Again I ask, why do you care? This is a Windows implementation detail,
behind the scenes.

grouporderlist is a windows inplementation detail,I understand.
But when there are only 2 drivers in the filter group why the index in
grouporderlist shows different number for each and every install.
This also happens if only I install the driver using my inf file.
If I install it using my setup application I dont see such things.
number of drivers in filter gropu is always 2 when I install using setup
application any number of times

I wonder if I am missing something in my inf file.

Thanks in advance
