Win 10 Fullscreen not working

[MacNala]

I have a number of Windows 10 Guests at different stages of update but they all exhibit an inability to go to fullscreen. When you use the fullscreen command (Host + F) the host machine resizes the window but the Win 10 guest does not. Host + F again restores the system correctly.

Is this a problem with VB or Win 10?

Env Host Windows 7 + SP! fully patched.
VB 4.3.30 plus guest additions
Guest Windows 10 Build 10532 (slow ring)
Windows 10 Build 10547 (fast ring)
Windows 10 TH1 release.
Guests Multiple Windows 7 + SP1 fully patched all respond correctly to Host + F.

To whom should I address the bug report?

Full Screen is working for me with Windows 10 guests and VB 5.0.4 and above on Windows, Linux and OSX hosts. Make sure Auto-resize Guest Display is enabled.

Thanks for the reply.
I have tried the Auto-resize command without success but cannot find the option you quote "Auto-resize Guest Display".
Where can it be set?
I also note you are running VB 5.0.4, I am still using 4.3.30 while the developers iron out some of the bugs in VB5. Is there a change in the way VB 5 handles screen resizing?

AKAIK AFAIK, there is more effort getting Windows 10 guests and hosts working in VB 5.0 at the moment. I haven't haven't used VB 4.* since before the first Windows 10 seed.

AKAIK means what? Google doesn't help.

[loukingjr]

as far as I know.

Oh you meant AFAIK!
That is in my limited abbreviation vocabulary.

Sorry for the typo. I haven't had my coffee yet. You could try the current VB 4.* test build and see if that works. https://www.virtualbox.org/wiki/Testbuilds
