Driver irql not less than or equal (bridge.sys)


Of course, it's a Blue screen of Death ( that conains a smiley ^^ )


The first time I've encounter this issue, it was the time that i've deactivated the Hyper-v in windows 8,
The BSOD pops up to me around 4 or 5 times successively, each time my computer restarts before the login screen .

and than i've decided to use my brain ( and yes i have one ^^ )

so, let's analyse the situation !

What is ( Bridge.sys ) : it's a virtual bridge created by the Hyper-V machine, in order to "Bridge" internet connexion to the VM you despose of.

- So ! it's related to NETWORK CONNEXION
We Know that windows analyse availible connexion in the startup time.

So ! Here The Solution :
easy ! you need to disconnect totaly your computer, ( turn off WIFI , unplug Cable ).

And Like Magic your computer starts normaly !

but wait ! don't tune on wifi or plug the cable !  you need some more steps :
  1.  Go to " Network and Sharing Center " in your " Control Panel "
  2.  Click on " Change adapter sittings "
  3.  here the unremoved "Bridge" that cause the problem
  4.  Remove it ^^

here you can connect your computer without problem.
Maybe this is a bug or something in the hyper-v disabling process
