Message:

Windows host installer: More fun for Windows 10 detection, as the former way often did not work and thus wrong / missing certificates were being installed (running .msi directly vs. .exe installer). We now use a custom action via VBoxInstallHelper.dll, which in turn queries the registry for the (hopefully) correct build number. Note that we cannot use any of the RtlGetVersion() / GetVersion[Ex]W() APIs here, as the Windows Installer service seems to shims those, sigh. bugref:8691
