Lost widescreen resolution after Windows 10 update

[yuri.weinstein@gmail.com]

I run headless VB (Windows 10) on ubuntu 16.04.1.
And use Remmina to connect to it.
Today after Windows 10 anniversary update I lost widescreen ability and wondering if other people saw this and if there is any fix for it.

Thx

Moved to Windows guests

Wild guess: did you update the Guest Additions? Does it also happen in "normal" mode?

1. Start the VM. Not from a saved or suspended state. Clean start. Log in.
2. Shut down the VM. Not suspended, not paused. Shut down.
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).

A Windows 10 guest will sometimes (for some unknown reason) decide not to display at the usual screen dimensions (mine did after the last Windows 10 upgrade). I have also seen this problem when you resize the screen and the desktop does not expand to fill the new window.

If a reboot doesn't fix it, go to the display settings in the Windows 10 guest and manually select the higher value setting.

I have the same problem. Can not rescaling it in windows and not in vm.
