Most "Smart" TVs use Automatic Content Recognition (ACR), essentially taking snapshots every 10+ms of what you watch and hear, then forwarding & selling that data to companies for ads, etc. I now feel it's only a matter of time before this "feature" finds its way to our ever "smarter" PC monitors.

LG with the help of Windows is already installing adware when the right Device ID is detected.

Obligatory: you can improve your Windows experience by installing Linux.

Non snarky comment: you can disable driver craplets from auto-installing using group policy or the registry.

run gpedit.msc
Computer Configuration
> Administrative Templates
  > System
    > Device Installation

Prevent automatic download of applications associated with device metadata
= Enabled

That will set the following registry key:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Device Metadata]
"PreventDeviceMetadataFromNetwork"=dword:00000001

This is interesting, but the following is not intuitive in relation to displaying ads on a display device:

Prevent automatic download of applications associated with device metadata

It confuses me what people say Linux is hard.

Most people will be on Win Home which usually locks you out of gpedit. Or ignores your settings there, some even from the registry. In the recent times there are even some GPOs locked for Pro and only available on an enterprise version or Windows server...

Holy crap I forgot the Windows Registry exists. Nightmare fuel
