I did a search and found nothing substantial so here goes: How anonymous am i on my wireless computer? How traceable am i on a p2p network? I should mention that i only access from coffeeshop hotspots. I guess what i'm asking is there some sort of viable means of identifying my computer and by extension me other than tracing an i.p. and a service provider and an account name.

Also along the same lines: When registering my computer i was asked to put in my name and did so thinking nothing of it. It turns out that the name i entered is now appears in the directory on the path "C:\Documents and Settings\MYNAMEHERE. As a reasonably paranoid person this is something i do not want. Unfortunately, since it is apparently a system file i can't change it simply through the right-click rename. Is there any way to alter the filename without reinstalling?
