Well, there are a couple of updates that I'm dubious about, given what their 'Genuine Advantage' tool can do to some people. I don't know whether I should just ignore them or if they may benefit me. Why can't they explain things in more lay terms?
Update for Windows XP (KB920342)
Typical download size: 782 KB , 1 minute
Peer Name Resolution Protocol (PNRP) version 2.0 allows you to publish and resolve peer names with other PNRP nodes running v2.0. This is important for peer-to-peer applications on your system.
Can this interfere with P2P apps due to the nature of some media shared on them?
Update for WMDRM-enabled Media Players (KB891122)
Download size: 5.9 MB , less than 1 minute
Install this update to enable your PC to access premium content protected by Windows Media Digital Rights Management.
Can this have negative results on any kind of media?
