Upper disk filter load order

Hello,

I like to track IO for disk object, Specially for OS post Vista. I want to explicitly do below partition manager. I understand it is the upperfilter key in registry where filters are listed.

Following questions are to make sure newer driver always load below partition manager

Is there a way to make sure upper disk filter drivers are loaded in a given order at every reboot?

Whether windows guarantee to load as per upper filter key?

Is there a way to load upper disk filter through inf to make sure it is loaded below partition manager? I wish not to write explicit program to change the registry for ordering

Just to add
I mean to get stacked below Partition manager.

I would like to share the test result.
I loaded the upper disk filter and rebooted the machine. Later I interchange the upper key (partmgr and NEWfilter) registry manually and attached new disk. I find the stack for the newer device is different than older disk w.r.t to upper filter

The key is read as the dusk is built by pnp, this is expected behavior

Is there a way through INF where I can set as first upper filter? i.e editing the registry
upper-filter key in a way where it is the first entry e.g. Newfilter Partmgr

No, you need code for that
