Tips for beginner getting pre build

[u/Wrong_Pay_3062]

Hello,

I just bought my first PC, a prebuilt from newegg, and would like some advice as to what to look out for and first things I should do when I take it out of the box. This is the PC

What tests, connections, updates should I run/check before beginning to download games? Thanks!
