Hi!
I have a Keyboard filter driver that ran fine in Windows NT 4,
but in Windows 2000 it fails in sytem shutdown after receiving
an IRP_MJ_POWER (for now I simply pass it to the next filter
in the stack).
There are special (Po…) functions to handle it (only 2000!),
but I want to maintain compatibility with NT4, so I can’t use them.
Any ideas?

Hi there!
If you want to use the same image for both OS’s and if you want to take a
very unconventional approach, you might want to get the exported addresses of
PoXXX functions at run-time. For that, you’ll need first to determine what OS
you are running via PsGetVersion, then get the ntoskrnl.exe memory offset via
ZwQuerySystemInformation with SystemModuleInformation and then to traverse
the PE export directory of ntoskrnl.exe seeking for the appropriate exports.
If you are interested in that, please respond to this mail either to the
mailing list or directly to me (xxxxx@gmx.net) and I’ll paste some
funny source how to do that 
Greetings,
Alex
