How do I program for windows 7 logon screen (not simply subtitude the background image)..Like I want it to authenticate with a RFID reader.Am I able to do that?I know XP could do this.But I found nothing relative to Windows 7 on google.
Back in the 2K/XP day this was done by implementing a GINA, but that disappeared with Vista. Now you need to use Credential Providers instead. This article might get you started in the right direction.

I am working on a windows application(C#) to monitor computers. Are there any way to get current power usage in windows ?
This is simply not supported under Windows. MS documents their PowerManagement API
I walked through every subheading, and nowhere can such detail be monitored. If the system is on battery and you poll the %battery remaining (which is not terrible accurate), you would know about as much as is possible through the API

There are many ways to achieve this - the .NET-Way is described here in this MSDN-Article:

Unfortunately Microsoft seem to have a patent for this approach in the USA at least: http://patft1.uspto.gov/netacgi/nph-Parser?Sect1=PTO1&Sect2=HITOFF&d=PALL&p=1&u=%2Fnetahtml%2FPTO%2Fsrchnum.htm&r=1&f=G&l=50&s1=8,024,775.PN.&OS=PN/8,024,775&RS=PN/8,024,775 , so depending where you're based you might run into legal problems.
