the setup log files will tell you why the reboot is required. the fixed button is opened by the kernel s0 it could very well be an open handle which is requiring it

Updating a filter requires stopping and restarting of the devnode.

Some devnodes are not stoppable - the boot hard disk, for instance. I expect FixedButton to also be such.

For such devnodes, reboot is required to update the filter.

I have a developed a WDF filter driver for the ACPI\FixedButton power button
device. After installing or updating the filter, device manager is prompting
for a reboot. Why is this reboot required? Does the system have open file
handles to this device? Is there any way around a reboot?

Thanks!
