win 10 guest crash after install extension pack on High Sierra

[freemanbobo]

The win 10 guest OS on iMac always crashed after install the extension package. I tried from 5.1.26 to 5.1.28. Every time I can repeat the problem after installed the extension package. Now I am running the window 10 without any extension package installed smoothly.

However I cannot use the full screen function.

Anyone has the resolution?

Thanks

You've got to be careful with the terminology. There are two distinct things:

• The Extension Pack (ExtPack) get installed on the host and it has to match the VirtualBox version. It provides functionality such as USB2-3, Webcam, VRDP, PXE, PCI passthrough on Linux hosts, VDI Encryption. You have to download it and install it separately from the main VirtualBox program, due to its license.
• The Guest Additions (GAs) get installed on the guest and it would be good to match the VirtualBox version, for anything other than enhanced graphics support. It provides functionality such as shared folders, shared clipboard, drag and drop, pointer sharing, enhanced graphics support. You do not have to download it separately from the main VirtualBox program, since it comes bundled with it.

I'm assuming you're talking about the GAs. You cannot get FullScreen without the GAs. Can you please download either the latest Test Build, or the latest 5.2.0 rc1 from the same page, but at the bottom of the page where it says "Development Snapshots".
