Error 0x80070490 trying to launch VM without SCVMM on Windows 2008 Server R2

Question

Hello everybody,
I get a weird issue trying to launch a VM.
This is the current situation : I get a server, Windows 2008 R2. I've only install Hyper-V and Failover Cluster. I can create a VM but when I try to launch it, I get an error message into a popup (translated from french) : "The application encountered
an error during modification of 'vm_name' state". "'vm_name' could not be initialize". "Could not initialize machine remoting system. Error 'Element not found'. (0x80070490). "Could not find a usable certificate. Error: 'Element not found'. (0x80070490)."
So, I'm unable to launch my vm's.
I'm not using SCVMM yet. I want to resolve this issue before.
I read some articles and posts about SCVMM certificate issue but I'm not using SCVMM.
More fun, I read articles about this issue but on Windows 2008 Server (not R2) : problem resolved by a fix, unapplicable on my Windows 2008 R2 :)
I'm totalyblocked and ain't got no idea how I can resolve it.
If someone gets I idea ...
Cheers,
Nicolas

Environment: Windows 8.1 in an Active Directory Domain (2012R2) with MS Certficates Services support NAP/Health Registry, etc. 
Error:  Attempts to start a Hyper-V VM on a machine generates the error message Error 0x80070490 trying to launch VM:
"'vm_name' could not be initialize". "Could not initialize machine remoting system. Error 'Element not found'. (0x80070490). "Could not find a usable certificate. Error: 'Element not found'. (0x80070490)."
Note: 
VMM can manage other Hyper-V servers in environment from same machine, just not local machine.
VMM on remote machine generates same error message when attempting to manage new VM machine
Certificates - Service (Hyper-V Virtual Machine Management) on Local Computer shows 0 certificates under vmms\Personal
Fixes Attempted and Failed except for #5!
1) hotfix directly: Windows6.0-KB967902-x64.msu -> Failed: 0x80096002, Windows Update Standalone Installer.  The certificate for the signer of the message is invalid or not found.
2) hotfix via pkgmgr: PkgMgr.exe has been deprecated. Please update scripts to use DISM.exe.  0x80070307
3) Reset Certificates: 
 Start > Run > MMC
 Add the Certificates Snap-In
 Select Service Account
 Under the Select Account to Manager, select Hyper-V  Image Management Service
 Complete the Snap-In Wizard
 Expand the Certificates under Personal Category
 Notice the certificate generated has been created ‘for the future’ (assuming you’re suppose to revert the date & time to 2010, the certificate should display as invalid because it was created at 2013)
 Delete the Certificate(s)
 Go to the Services Console and Restart all Hyper-V Services
 Result: No certificate auto generated
4) Uninstall / reinstall hyper-v service and management service addons from Windows features.  
5) ‎did the following from http://technet.microsoft.com/en-us/library/ff935311(v=ws.10).aspx (WORKED!!! -> Note, their PS script has an error, add a dash(-) before the word recurse)
reg add "HKLM\Software\Microsoft\Windows NT\CurrentVersion\Virtualization" /v "DisableSelfSignedCertificateGeneration" /f /t REG_QWORD /d 1

$cert = @($certs)[0]
$location = $cert.PrivateKey.CspKeyContainerInfo.UniqueKeyContainerName
$folderlocation = gc env:ALLUSERSPROFILE
$folderlocation = $folderlocation + "\Microsoft\Crypto\RSA\MachineKeys\"
$filelocation = $folderlocation + $location
