This pertains to Networking or Win7 or browsers, because I don't know who's doing it. File it under CREEPY:
My machines are networked but I don't use any synching software. I usually just copy my Waterfox bookmarks and Thunderbird mail to the 2nd machine at irregular intervals. I use a branch of Firefox called Waterfox, which is almost identical except the telemetry. It uses 95% of the same extensions.
When I add pages to my Bookmarks on the HP, they update on the Gateway too. It saves me some work, but Id like to know how it's happening.
