You can turn the telemetry and Recall off in the Windows settings. The privacy & security tab has everything.

Copilot can be uninstalled with Revo uninstaller like everything else.

You can remove it. There is actually an “IoT Enterprise LTSC” edition that is fresh from the start, though it may not support the very latest hardware so install 11 Pro then use Revo uninstaller’s Windows apps tab to remove the junk.

I wouldn’t recommend it. Just install ExplorerPatcher to get the old UI back.

The amount of telemetry is essentially the same and most of it can be turned off in the settings.

My 2.0 signal advice is for those using the built-in TV speakers or a soundbar who wonder why dialouge is so quiet.

Also, most TV’s don’t have an arbitrary slider for gamma. 2.2 is a target that many of the same model of TV should be within about 0.5 of when selected.

That advice is for those using LCD TVs with a 300 nit max brightness, not a 1000 nit OLED where BT.1886 may be more appropriate.

Set the gamma to 2.2 and make sure the eco mode is turned off.

You should also select the 2.0 audio track when available, or try the dynamic compression/volume normalisation setting.

It’s pretty new

Almost all TVs come with a power saving or eco mode enabled by default which ruins visibility. Find that in the settings and turn it off. You should also turn off motion interpolation (e.g Trumotion, Clear Motion Plus, Motionflow) so motion doesn’t become a smeary and artificial mess.

You can usually fix it by turning off power saving/eco mode and setting the gamma to 2.2 on your TV. You should also turn off motion smoothing (Trumotion/Auto Motion Plus/Motionflow/Clear Motion) so motion doesn’t look overly smooth and fake.
