I have installed guest additions on my VM a couple of times now but I still can't get the resolution to go full when the its in full screen, I've tried Host + G but still no luck.

Thank you

Minimum information needed for assistance.

Hi,
Sorry about that.
Virtualbox Version: 4.3.26
Guest Additions installed? Yes
Host Info: Yosemite, 64 bit, 150GB
Guest Info: Windows 10, 64 bit, 32GB

you actually have to run the guest additions installer from the CD once it's mounted. not just attach it to the guest.

Thats the thing, I do run it from the CD and then when it reboots the resolution doesn't change even with Host + G activated.

did you try just dragging the screen to a different size?

FWIW, Windows 10 is being flaky. It insists on updating to 10041 even though it updated twice before.

I't's already full screen though?

If it's already full screen did you try Host+F?

Yeah :/

it's stuck in full screen?

I can't post an image because i haven't been a member long enough but no it's not stuck. It's full screen but there is a black box around the OS instead of it being 1:1

okay, well, I just downloaded the 10041 .iso to do a clean install. I'll install the GAs and see what's up. BBL.

Thank you!

Don't know if this will help but I had to right click on the W10 desktop and select screen resolution before screen resizing worked. That is different than in the previous W10 builds.
