Screen resolution when maximize window

[Fulvioval]

Hi friends, I need a little help.

Recently I change from VMware Player to VirtualBox to use a virtual Windows 7 with Windows 10 as host. I'm activated auto-resize but when I maximize window of guest system, resolution still small, only filling a little portion of maximized windows. What I have to do to have a guest system resolution in size of maximized window?

Thanks for any help.

Please provide a VM log file: with the VM fully shut down, right click it, save "VBox.log" (ONLY) to a zip, and attach the zip here.

Did you install the Guest Additions? (Chapter 4).
