Windows 10 21h2 (OS Build 19044.2006). The only error code is from Google Chrome (which I forgot to mention also is failing to update), which is "An error occurred while checking for updates: Unable to connect to the Internet. If you use a firewall, please allowlist GoogleUpdate.exe. (error code 7: 0x80072EFE -- system level)." Error from Windows Update when selecting a manual update says "We couldn't connect to the update service. We'll try again later, or you can check now. If it still doesn't work, make sure you're connected to the Internet." I'll try your suggestion later today and report back. (BTW, I'm writing this from the device with the update problem, so obviously the computer CAN connect to the internet.) [KIS 21.3.10.391 (j)]
