How do I stop those annoying painter marketing / advertising pop ups?

I can find no setting in Painter 2021 to turn them off.
There is no "Do not show this again" checkbox on the pop up.
And the Windows trick of disabling the CorelUpdateHelperTask and CorelUpdateHelperTaskCore tasks does not work because it sometimes causes problems with starting Painter.

It's not that they pop up during Painter usage - I would expect that.

But they pop up when using other applications when Painter hasn't even been run on the system!

Plus, they sometime pop up in the lower right of the monitor in such a way they are partially off the screen and I cannot click an "X" to get rid of them.

I have actually lost work and time in other applications because they pop up over the Save button (like in Photoshop) and the only way to get rid of the pop ups is to reboot the system - WITH ALL THE WORK I HAVE DONE IN PHOTOSHOP LOST!

They are beyond annoying and far too frequent.

HOW do I STOP them?
