Windows 4.3.18 specifically for errors due to security

This topic is now obsolete. A 4.3.20 sticky topic has now been created. Please move the discussion there.
---- Original opening post
This topic is specifically for Windows users that may still have issues seen in version 4.3.18 when the security was strengthened.
Please note that to be taken seriously you need to post a few items as attachments (compressed is preferred)
Note that, as in the previous (4.3.14, 4.3.16) discussions, the purpose of this topic is to gather diagnostic data needed to solve the hardening issues, and nothing else. Wibble posts, opinion posts, and posts that don't include necessary diagnostics will most likely be deleted. If a test build is created then you'll be expected to have tried it before you post.
Please be explicit about errors. Don't say "same as xxxxx". See list above for what's required.
Test build #1: VirtualBox-4.3.19 (rev 96923)
Relevant changes since 4.3.18:
* Fixes problem loading some 3D related graphics DLLs (associated with drivers).
* Fixes VBoxDrv BSOD caused by race during process creation.
* Fixes VBoxManage crash when getting shared folders from saved state (++).
Please give the test build a spin before posting.
