Can't start VM just after windows login

[pseudo555]

I create a XP VM a long time ago, and i keep updating virtualbox.
My host is a windows 7 64bit up to date.

Since two or three last virtual box release I got this message when i start to launch my vm :

Code: Select all

The virtual machine 'xp' has terminated unexpectedly during startup with exit code 1 (0x1).  More details may be available in 'C:\Users\pseudo555\VirtualBox VMs\xp\Logs\VBoxStartup.log'.

Code d'erreur : E_FAIL (0x80004005)
Composant : Machine
Interface : IMachine {480cf695-2d8d-4256-9c7c-cce4184fa048}

I got this message if i try to start my VM just after windows logon. After a while (2-5 minutes), the VM can start without trouble.
So why can't i start a VM just after my windows logon screen ?

Edit :
Vbox 4.3.24 r98716
attached log file

1bb8.1bbc: supR3HardenedMonitor_LdrLoadDll: rejecting 'C:\Windows\system32\crypt32.dll' (C:\Windows\system32\crypt32.dll): rcNt=0xc0000190

Take a look at:
- 4.3.20 rejecting crypt32.dll after Windows patchday
- Windows 4.3.24 specifically for errors due to security

If you read the log you will see the error and then all you do is ask google about it at site:virtualbox.org
"C:\Windows\system32\crypt32.dll site:virtualbox.org"
