Not so sure that the KB text description in control panel will give enough info.

It's only after months of reading about it do I know enough to discern that diagtrack.dll == "telemetry".

The statement 'Which you can decline to install' makes it seem as if this is specifically flagged and you have the option of not installing it.

In reality you are describing the standard options: Automatically Update/Let Me Choose Which Updates/No Updates at all.

When users are advised to install this stuff for their own good for security purposes(Microsoft Recommended), and yet this is basically malware/a keylogger - it's pretty bad in my opinion.
