On the "system" screen (Control Panel -> System, or [Windows+Break]), you should find a line at the bottom: "Windows is not activated. Activate Windows now." Click on "Activate Windows now", that should be all you need to do.For your second problem, you may check your network/security settings or policies.Mobile AMD64 3000+, VIA Apollo K8T800 chipset, 1 G RAM, ATIRadeonMobility 9700, 20x DVDRW, C:XPSP3 (55G),D:WIN7 (25G),F:DATA (250G)
