Didn't they already do this? I thought I remember after a Windows 11 update a couple of months ago I had that copilot shit on the taskbar and auto-enabled.
I'm in the insider program (been too lazy to reset my computer and leave it) and for a while it would auto launch with the sidebar open for a bit. I had to close the copilot sidebar every time I booted my computer. They have since removed that "feature"
