fail to write files in SystemRoot in Vista

Hi,
I have a driver that works well in WinXP. In this driver, device property
page write some information in systemroot directory. (just like logging
files). But in Vista, the property page fails to write because it has no
authority, so some relative feature can't work.

1. I've tried to change the writing file to non-system directory, but I
found that INF failed to use dirIDs failed.

[DestinationDirs]
CopyFiles.ProperPageLog = 53, VendorDir ;try to copy to user profile
directory

the 53 dirID works in winXP but no in Vista, I've tried "25 (Shared
Directory)", "16427 (Program Files\Common)"...they all fail in Vista.


2. another question, if I copy the files in installation package, how to
access this diretory in dirver (ex. "16427 Program Files\Common")? As far as
know, the \\SystemRoot refer to "c:\windows", but can't access other
directory. I think absolute directory like \\dosdevices\\c:\\ is bad idea.


I'm not sure I'm in right way, please help me and thanks!

Can you use ETW or Windows event log for logging, and registry for settings, to
avoid the need of these files?

Accessing "Program Files" from a driver is also a bad idea.
