Not a lawyer, but it's up to you and your system. There are ways to stop updates and also to stop that nagging. Google a bit, use wintweak ...

And then, there are ways to set the update time and to postpone that.

That dark pattern is as long you have internet. No internet, another Button "no" will appear.

I'm always on Windows. The first things I do after a fresh install is to remove bloatware (with scripts, or Software debloater, switch off the the telemetry (google for winaero, or shut up windows), switch off the auto reboot (google for a way to stop win10 reboot after updates. The one where you have to replace REBOOT.AC and other files is the proper one) and creating a fresh profile without the bloatware, delete the first created Profile. Takes around 15mins of time.

Have fun, M8!

I did run this debloater in these two machines from the beginning of their setup: https://github.com/Sycnex/Windows10Debloater

These are paid and fully licensed versions of Windows 10, and yes, I am now aware of the registry hacks to try to delay this. Only run these two laptops, because are forced to use some apps that are only available for Win10. Otherwise would dumpster fire the whole Microsoft crap.

What shocked me was the whole intrusiveness of window. A complete grab of the screen that makes you believe this is some kind of forced emergency upgrade. Under Windows Updates, you can choose the "Delay for Now". It was not there before, and must have been installed in one of false Microsoft Security Updates. The whole Microsoft thing stinks of lack of respect for the user, and misleading dishonest patterns and I had enough of it...Win 11 is not yet stable, and not all apps are compatible and had or my assistant upgraded it, could have causes serious compatibility issues.

Somebody else messes with your systems with no warning, before an important meeting, either at my office or 2000 km away from Redmond, I am going to bitch about it...
