Attention Windows 7 beta users , up to five (5), I said f-i-v-e test updates are coming via Windows Update tomorrow (February 24). These updates are strictly for testing purposes, our friends in Redmond tell us. By the way, you must install these updates manually via Windows Update - even if you run WU in Automatic mode. BTW Mark 2: these updates replace some system files with the same version that's already on your system.
So, what's the point of running WU and selecting these updates? Mama Microsoft want to make sure it can update Windows 7 properly. Don't want to play? See the Microsoft Update Team Blog to learn more .
