What I like about pihole vs. dedicated ad-blockers, is that a pihole can block telemetry as well. There are lists of Microsoft and other data-gatherers you can import, and even if you can't stop the data collection, it dead-ends the attempts to upload it.
The speed of transcoding video using FFMPEG on a non-GUI installation of Debian, on an old small-form-factor PC - 2nd-generation i7, 16GB ram, 240GB SSD.
You will continue to receive Windows Defender updates. I have a Windows 8.1 tablet that keeps updating Microsoft Defender antivirus. It's only used to connect to RTSP streams for music.
Ah yes, that's a concern - but I have a job in Task Scheduler that re-writes my registry tweaks - mostly changing various tasks back to "disabled". You can trigger it hourly, or on an event. As soon as a selected event - such as a telemetry switch-on - hits the event log, the "disable" script runs.
There's other ways, like taking ownership of the executables and changing permissions to lock out the "SYSTEM" account.
And pihole blocks DNS resolution of the telemetry harvesters as well. Windows update won't touch that.
It's not 100% effective, but I couldn't be bothered to take it further.
Wasn't Klein the manager defending George Harrison against the plagiarism claim against "My Sweet Lord" (vs. "He's so fine"), then Klein switched sides and was the plaintiff on behalf of the "He's so fine" writers?
You know, if you copied those three lines into a text file, then saved it as bypassnro.cmd, you'll have solved that problem.
