After reflexion, i wiil use the postinit script … Why ? Because if i receive a new model with the VBoxMouse.sys conflit driver, i will need to search again the culprit file into the Driver Pack … and waste many times …
So, in the fog.bonus, i added this :
# suppression du fichier VBoxMouse.sys ... eviter conflit et BSOD avec les Optiplex5050 durant SYSPREP (au 2nd reboot, durant verif perf. videos)
rm /ntfs/Windows/System32/drivers/VBoxMouse.sys
echo "Suppression du fichier VBoxMouse.sys pour eviter BSOD durant SYSPREP (au 2nd reboot) ... Done !";
I also added this in the SetupComplete.cmd :
rem uninstall VirutalBox Guest Additions : eviter les BSOD comme VBoxMouse.sys sur machine cible
"C:\Program Files\Oracle\VirtualBox Guest Additions\uninst.exe" /S
I retried a download task on the Optiplex 5050 … and no BSOD 🙂
So … just many thanks again George for your help ! Knowledge growth up !
PS : how can pass the subject to “Solved” ?!
