Dont know if this has been posted or not yet but here goes.

Some pcs seem to be having a problem not shutting down all the way and displaying the "It is now safe to shut down your computer" message. If you get this one possible fix is to go to the device manager and then go to the view button click show hidden devices and you will see another device show up in the list which will have a picture of the windows install logo (looks like a box with cd's beside it) sorry but for the life of me I cant remember what it is called. but enable it and tada! It will now shut all the way down.

Thanks to NOONOO of teh windrivers chat for providing me with the info.
