I have recently purchased a bunch of broken Netbooks of which most came with a Genuine Windows 7 COA. The problem is it does not seem to matter whether I use a Factory Install Partition to install windows or a Fresh Install from a USB Flash with the Windows 7 Starter ISO available for free online. Ok here is what happens I will go through the normal installation process even multiple times, and may be able to obtain updates sometimes but then regardless when it comes to receiving the latest Windows Update Agent (the one with v xxx.320 at the end) It will no longer find updates, and if I go to "check for updates" I will get an endless check screen until I reboot the Netbooks (Acer D255, D255e, D257, D270, ect). I have also tried wsusoffline.zip, and still to no avail. Also I might add I tried the windows update readiness tool, and even tried to install the windows update agent manually.
Please help anyone if you have an idea of what the problem is. I have been doing this sort of thing for more than a decade and a half, and still not sure what the issue is.
