I have been offline for a while fixing my Asus PC with the errant update. All done now, thankfully It was a minor problem for me. After the update was installed, not noticed at the time, on boot up, the PC reported a CPU fan error, press F1 to continue and it cleared each time. I have been busy so was just another task to do later. When this report came to me I thought it was now important to do. Now, without the update the fan fault has been cleared. I will be more diligent next time.
