I just received a HP laptop - it's a ZBook workstation (beautiful i7, 16GB, 3840x2160 screen).
It's running Windows 7 (funny it came with a Windows 10 DVD as well and recovery DVD even though there's no optical drive on this machine). Anyway. Boot up and started Windows Update. Since this is a fresh laptop I would expect to see lots of updates but instead it's been running the "Checking for Updates" for the last two hours and nothing.
