> 1. Not at all - Complete revamp and its now all back to MS and they are cloning another Linux approach (about time too)
Do any Linux distributions do it that way? Hmmm, apart from paid Red Hat / SuSE.
Everything else (CentOS, Debian, *buntu, etc) retrieves the latest package list from a mirror site, compares that to the local install, then pulls down only the outdated bits.
Not really a "send all the install info to central server" approach.
Shouldn't take too many bad quarters for MS to begin using that for "licensing validation" purposes. Even if they say otherwise for now.
