Three reboots is the norm now for my three machines. This is how it was explained:

The firmware push: Windows pushes the certificate data into your system firmware.

The bootloader load: The system restarts to load the newly signed bootloader.

The final application: A third restart allows the motherboard's firmware to permanently apply the new certificates.

That's with no fast start-up on my machines.

I have no idea why I don't get that progression, I was sitting in front of my machine for the last update, there was one boot after the update loaded and finished it's install. There is no new certificate data required on my systems, so that could account for one missing boot.

Yes.. Apparently you can't skip this one. I was busy with other things then the reboot screen suddenly popped up. This while MS suggested that if your not affected you can skip this one.... Oh well the benefit of this update that it finally removed 79 old packages from build 26200.8737. (They forgot to do that with the previous update; 26200.8875) 🤷‍♂️

Not sure which unwanted update caused it, but my PC now suffers the controller Guide button opening Task View feature. There was a number of posts about this last year but not much since.

Someone likely felt a poorly implemented triple function of the Guide button was too good to not keep rolling out. Short-press opens Game Bar but a medium-press now opens Task View along with an annoying controller vibration. Keeping it pressed does eventually turn off the controller - the function actually wanted - but Task View remains on screen which any testing should have spotted.

Turning off Xbox Mode - that's appeared in settings - does stop Task View opening - but the controller vibration still occurs - again something that should have been corrected by now.

The PC was built for gaming but the mouse launches games perfectly well and the controller is only needed in-game - no need for Xbox Mode or Big Picture Mode or Task View etc.

Why is it impossible to go more than a couple of months before the Windows experience gets worsened by some improvement?
