@croc - telemetry
Unfortunately, I can't confirm the extent of the telemetry. I've been uninstalling/hiding telemetry-related updates for a month or two, ever since the first indications came out as to what they were up to.
It is often said in Microsoft's defence that you just need to opt out of the CEIP and nothing is sent. What I see is Microsoft continually attempting to enhance the telemetry generation in Windows 7, using deceit if necessary. I think there will certainly come a point where opting out of CEIP will no longer block the telemetry.
Microsoft cannot be trusted and I take the view that the only way to deal with them is to treat all updates as suspicious and to ensure that all telemetry-related tasks are actually disabled.
