Microsoft Windows 7 and 8 Spying on You:
How to uninstall updates (I haven’t tried this yet): If you don’t want these new tracking tools on your PC, the best thing to do seems to be simply uninstalling the offending updates, then blocking them from being reinstalled. To do so, head to Control Panel > Programs > Uninstall or change a program. Here, click View installed updates in the left-hand navigation pane. In the search box in the upper-right corner, search for the KB3068708, KB3022345, KB3075249, and KB3080149 updates by name. If they’re installed, they’ll pop right up. If you find one, right-click on it and select Uninstall to wipe it from your system.
To block the updates from being downloaded again, dive back into the Control Panel and head to System and Security > Windows Update > Check for updates. The system will look for updates, then say you have a certain number of updates available, separated by status (Optional, Recommended, Critical). Simply click the recommended updates link, find the KB3068708 and KB3022345 updates, then right-click them and select Hide update. Boom! Done.

Modem – Comcast requires DOCSIS 3.0 compatibility as of 2015/2016. Here is their list of compatible modems. If you have the Xfinity phone service don’t assume that the listed modems will handle a phone. It looks like most of them don’t. And one that is not DOCSIS 3.0 won’t work just for the phone even if it does have phone capability.
Typing http://192.168.100.1/ in an internet browser should access your Comcast modem. Username will likely be Admin or something, or maybe your account nickname or your in-home network connection name. Password would be something you or whoever connected your modem created.
