I couldn't actually tell you if Copilot is useful, because it is so persistantly annoying that I detest it on principle as a program, before we even get into the genAI of it all.
My last laptop had a Copilot quick access button.
Immediately to the left of the left arrow key.
I live for keyboard shortcuts, so the fact that I could so easily and frequently and accidentally launch a program when I'm just trying to toggle screens or highlight a block of text is already infuriating. But add that this particular program is so resource-hungry that it can freeze a gaming laptop that runs BG3 at max graphics quality without blinking sent me into such incoherent rages that I wanted the entire program obliterated from the machine.
I did successfully remove the entire program. BUT THAT FUCKING KEY. Tapping it no longer opened a CPU-hungry program, but it still opened a window prompting me to install and update Copilot.
I finally pried up the key and surrounded the soft part of the switch with epoxy, so the key simply no longer moved if I accidentally touched it. I voided the warranty on a $1500 gaming laptop to make Copilot stop fucking bothering me.
Is it good AI? I have no idea.
I'm still not even sure what it's supposed to do to improve my Windows experience. All it did was deteriorate my Windows experience until I was driven to hardware sabotage.
