Following Anderson's hunch, I put in KB 2952664 on a refreshing buy windows 7 professional SP1 x64 Pc. I had been disturbed to discover that it adds a system for the Windows Activity Scheduler referred to as DoScheduledTelemetryRun. That entry did not exist just before I put in KB 2952664.

You'll be able to see it on your Computer by citing Activity Scheduler (sort activity scheduler inside the locate box), then around the remaining go right down to Activity Scheduler Library/ Microsoft/ Windows/ Application Expertise. There you are going to locate the Microsoft Compatibility Appraiser activity, established to operate at 3:00 a.m. each working day.

The Microsoft Compatibility Appraiser activity operates %windir%\system32\rundll32.exe appraiser.dll,DoScheduledTelemetryRun with all the description "Collects system telemetry info if opted in for the Microsoft Client Expertise Advancement System."

I identified the system operates regardless of whether or not you have opted in to the microsoft windows 7 professional Client Expertise Advancement System (CEIP). And even though you decide out, the system nevertheless operates.

Can somebody inform me why Microsoft is executing a telemetry operate on PCs that have opted out in the CEIP? This final results from an "important" update inside the Automatic Update chute, for heaven's sake.

There is an further query, regarding the Scheduled activity AitAgent, which appears to become connected. AitAgent was already put in and functioning on my PCs just before KB 2952664 was put in, so I couldn't operate it down. Should you can, remember to enlighten all of us inside the remarks.

The unique thread around the Answers discussion board was mostly and rightfully involved regarding the CPU overhead of operating the cheap windows 7 home premium Compatibility Appraiser. But I can not aid but surprise if there's some unauthorized snooping going on too.
