I just purchased a new ASUS G771Win 10 64 bit JW-T7187T Laptop with the following specs:
Processor i7-4750HQ Turbo 3.2Ghz
16Gb memory
2Tb Hdd
Gforce GTX 960M
The previous and current computer has WinXP Pro.
This is a huge change and I'm not sure what to do, I haven't been game enough to turn it on even!!

I suppose the first thing to do would be to try and connect to the internet but before I do is there any advice on firewalls etc?
The second thing would probably find a tweaking program.

All advice for this and other things/problems I might run into would be appreciated.

(I assume there would be a huge difference between Win XP and Win 10)
Thanks in advance.
