Change registry at the boot

[mara-]

Hi,

I'm wondering if it is possible to change some registry at the Windows boot. I'm trying to change some registry entries which are locked when Windows starts. I did some investigation and I discovered that key becomes locked after Kernel-mode device driver that implements the file system are loaded (I read something here about startup type.). So I need to make a change before that. Does anybody knows is this possible and how can I do it?

Thanks in advance for any help.

Cheers

If you do not need to change this key at every boot, or you only need to do it once, you can edit the offline registry.

Thanks for reply.

Well, I would need to change it every time. I know I can do it with driver, but how to create simple driver that can do this. Any application/tool capable of creating driver with .sys extension?
