I have an Acer Ferrari One laptop with Windows 7 Home Premium x64 preinstalled. Just recently, everytime I try and get windows updates, it gives me a 8024402F. The KB for the said error suggests that this is a network problem, but in my case, there are two computers connected to the network, all of them windows 7 x64 and the other computer, a PC, didn't have any windows update problems.

I already referred to that KB as what i have said earlier. I have tried the suggested solutions, but none works. My internet connection is good, and another windows 7 pc connected to the same network as this laptop has its windows update properly working so i think this is not a network related error but rather software related. What can I do? Is there anyway to reset windows update on windows 7?
