[German]On September 13, 2017, Oracle has released VirtualBox Version 5.1.28. It’s a maintenance update, that fixes several issues. But it raises new issues with Windows 10 guests.
I’ve blogged about this update at VirtualBox 5.1.28 verfügbar (German). Details about improvements may be found within this change log. The new version can be downloaded for Windows, Mac OSX and Linux from this download page. Please note that an updated version of VirtualBox 5.1.28 Oracle VM VirtualBox Extension Pack is also needed (to use extended features).
Extension pack 5.1.28 is causing trouble with Windows 10 guests
Shortly after I posted a link to my German article at Google+, I received a feedback from German reader Matthias Seidl. Matthias informed me, that he had serious issues with Windows 10 as guest. The root cause was the Oracle VM VirtualBox Extension Pack for VirtualBox 5.1.28. He downgraded to VirtualBox 5.1.26 and its Extension Pack.
A VirtualBox ticket
Matthias informed me in a 2nd post, that the issue already had a ticket No more elevated rights after install of Guest Additions 5.1.28 on Windows at Oracles VirtualBox site.
After installation of the Guest Additions for Windows 5.1.28 on Window 10 Pro no more programs with elevated rights can be executed. There is always a popup saying “The extended attributes are inconsistent”. I found no way to execute anything with elevated righs. I am running Virtualbox 5.1.28 on Ubuntu 16.04.
Other users confirmed this issue with different versions of Windows 10. Problem is with VBoxOGLpackspu.dll.
