what is, in your opinion, best way to become real Windows, advanced administrator? Of course it's possible to obtain MS Certificates, but they're rather very expensive.

Almost two years of everyday working on Linux machine, teach me, that it's very important to read system logs. Anyway, I assume that it's enough - I think that you must be familiar with almost any hive in you registry and each trick in Windows CMD and VBS- although it's high time for PowerShell, still on many maschines, you have only an opprotunity of using CMD by default (and their owners are reluctant to install anything else).

How I can accomplish this task? Which groups follows (superUser - it' obligatory), which articles read?
