VirtualBox resolution/guest additions

I have had similar problem. Win 10 host - Win 7 guest. I have had 1400*1050 max resolution on both Full HD display.

My steps:

1. Reinstall: vbox 5.1.4 to vbox 5.1.2
   
2. Run command in virtualbox program folder: "VBoxManage setextradata global GUI/MaxGuestResolution any"
   
3. Direkt download on host vbox guest additions 5.0.16 (other build don't resolve the problem)
   
4. Mount to the client the VBoxGuestAdditions_5.0.16.iso.
   
5. Start client
   
6. Install the guest additions from the mount.
   
7. Restart client
   
8. Set desktop integration and/or full hd resolution on client.
   
9. Kill vboxtray application process in client (high processor usage, killed the performance) Be patient!
   
10. Rename VBoxTray.exe in client, 2 places. (program files\oracle\virtualbox guest additions and windows\system32 folder)
    
11. Reboot client.
    

Result: I can use full hd resolution. The shared clipboard doesn't operate for me, but I can live with feature.

 

Problem accessing shared folder in VirtualBox (Host is Mac OSX. Guest is Windows 10)

I have been running Windows 10 in VirtualBox and accessing files across OS's via a shared folder.

Windows updated this morning and now I've lost access to the shared folder.

I've removed the folder from the VirtualBox Shared Folder list (Windows is booted up). Have re-added the folder (Automount and Make Permanent set). I've restarted a number of times. No impact.

Tried re-installing VirtualBox Guest Additions. This fails with "No device Ids found ...unknown error (0xE0000301)".

Have re-downloaded VirtualBox and re-installed. Still no share and still can't install guest additions.

Can anyone help?

 

Beta VirtualBox Guest Additions working

If anyone is using VirtualBox the test version of guest additions 4.3.21.97986 from here Testbuilds – Oracle VM VirtualBox seems to work with build 9926. The display adapter driver now loads correctly (which doesn't work in the current 4.3.20 version).
