Hello again friends and thank you for looking. I have been repairing PC's and doing new builds for quite a while now. I am going to sit the A+ next month and i feel i am at the level needed to pass. After that i want to start learning networking,but before i do i want to learn XP inside out. Although i feel its possible to pass the A+ with a fair xp operating system knowledge i want to learn it well. Things like event viewer/performance/data sources ect. Where can i learn this??Any good books? Please advise
