Update: The update spontaneously installed. Strange but just glad it worked.
---------------
Didn't take for me. Tried 4 times. The update downloads and reboots but when it reboots, Windows reports that the update failed. I look into the device manager and 3 things show the warning icon: Surface Management Engine, Surface System Aggregateor, Surface UEFI. I looked at the events logs and it reports "Installation Failure: Windows failed to install the following update with error 0x8024CE0E: Microsoft driver update for Surface System Aggregator Firmware.". The error's details say "This device cannot work properly until you restart your computer. (Code 14) Click Restart Computer to restart your computer." However I've rebooted a bunch of times and no luck. Rolled back driver and tried again, no luck.
I'm on Intel video driver 20.19.15.4364. I had installed the non-official Intel Video drivers but uninstalled them and tried the update again. No luck. I'm plugged in, no programs are running. Not sure.
I've only had the Surface for 3 days, frustrating.
