lately i had to fix few PCs by installing fresh windows 7 sp1 x64. for some of them i used simplix pack to update windows 7, but few users don't want to use that tool and i've been told to set up windows to download updates directly from windows update in control panel. everything goes well, windows is activated, LAN drivers installed to latest versions, internet speed normal, get updates from other microsoft products is also installed from microsoft site and turned on, BUT here is where the problem starts - when i click to check updates for windows (since it's clean installation) it's checking for updates forever, green bar is moving, cpu usage and ram starts to increase, but checking for updates never finishes. i tried with disc cleanup, restarting pc several times, but no success. it keeps hanging on "checking for updates". does anyone know why this is happening and how to slove it? thanks.
