Bitman,
I freely admit that I am not enough techy to understand the inner workings of PG or the registry. I am quite happy to leave things on default in general though I try to follow the advice to learn more.
The point you misunderstood though is that winlogon.exe is by default protected from reading. Your quote re read access must refer to other programs, but if you look at http://www.diamondcs.com.au/pgdb/ind...s=winlogon.exe you will see that it does not normally refer to this file.
