Win 10 Anniversary (1607) - lost screen resolution

[SBoat]

I have a Macbook Air 11 inch with the OSX Sierra 10.12 Beta (16A286a) and VirtualBox V 5.0.26.

I upgraded from Win 10 build 1511 to 1607 and lost the Macbook Air 1366 X 768 resolution. It was not available in the Win 10 display settings. For now I uninstalled the Win 10 update and it works fine with Build 1511. I wanted to post this because I think there needs to be a GuestAdditions update.

According to the forum rules, duplicate posts are not allowed. It's not good etiquette. So, I've deleted your post from Mac OS X Hosts.

Please post a VM log file.

1. Start the VM. Not from a saved or suspended state. Clean start.
2. Log in. Shut down the VM.
3. Right-click on the VM in the VirtualBox Manager. Select "Show Log..."
4. Save it (just the first log), ZIP it and attach it in your response (see the "Upload attachment" at the bottom of the form).

Thanks. I reinstalled the update and had the same results. Attached is the log.

I was looking again and I'm embarrassed to say that all I had to do was check the 'auto resize guest display' option. I don't believe it was checked with the pre-update Win 10 version but it now seems to render in the full screen mode. Windows 10 "change display settings" also now lists 1366 X 768 where it had been missing.

It seems to be good for now. Thanks
