Changing driver start method from within driver

NTDEV
1

I’ve got an unusual requirement.
I must change the driver start method from DEMAND to AUTO
after my driver loads (i.e., to take effect on the next boot.)

What is the recommended way of doing this?
(Directly changing the registry entry?)
I would likely do it during DriverEntry.

Thanks.

So write the registry entry.

This is a classic, old, method to keep a bad driver from preventing the
system from booting :slight_smile:

Yes, in DE, you can change the registry settings.

Be aware that if its a PnP or WDM driver you should not use AUTO.
