Software hive access at Start = 1

NTDEV
1

I have a highest-level driver (not FSD) that I may need
to load early (Start == 1) instead of on demand.

The hive \Registry\Machine\Software is apparently not available
at that time. Is there a recommended way to determine when this
hive is available other than to try to read it until success?

Currently I’m just using a timer which is imprecise.
Also, wouldn’t this be better handled by the Reinitialize
(recalling until success) procedure?

Thanks.

Can you control if the information is placed elsewhere in the registry?
If you can, put it under hklm.…\services<yourservice>\Parameters.
That is guaranteed to be loaded when your driver is loaded.

Thanks D, but I should have been more specific.

I want to access SOFTWARE in the registry to get the boot drive.
Perhaps there is another way to do this?

It is much better to keep all your data in System hive.

The solution is in the name passed into DriverEntry. If you strip off the
parts you don’t need, you will know the SystemRoot value. You can establish
this by using %SystemRoot% in the .INF file and install program.
