The tips, ads, and recommendations you see will be more generic and may be less relevant to you.
And this is treated as a bad thing?!
The number of ads you see won't change, but they may be less relevant to you.
Send only info about your device, its settings and capabilities, and whether it is performing properly.
In other words, even after turning off all the settings, your data still gets collected.
The rest of the installation process wasn't fun either. It was worded in this weird, condescending tone, like "Let's get everything set up for you", and "Let Cortana help you get things done!".
Thank goodness for FLOSS and GNU/Linux.
I love the "Let's finish setting up your device" popup that prevents me from using my VMs regularly.
Like some condescending peddler trying to slam-dunk your agreement as a foregone conclusion.
Come on, buddy, let's do those remaining tasks, let's have Microsoft scan your face, tell Microsoft about your phone, let's go and install those Microsoft apps missing from your phone, and your laptop, too, and then we go buy that Office subscription and have you store your important files on Microsoft's servers and we really need to get around to switching to Microsoft's web browser now.
And the only option you get is "Yes" or "Remind me later."
If you turn it off (and it needs to be turned off in two places), it'll be back on as soon as Microsoft publishes the tiniest update to any of its unwanted services. Harrghrrr! (artery popping noises)
Turn off "Offer Tips and Tricks to finish setting up this device" ( At least for me that was permanent. Otherwise you might use something like O&O shut up 10, also the setting is per user )
ShutUp10 is the GOAT.
