I do have some weird looking non P&P devices in my Device Manager.

Anyone got a clue what the hell they are?

I also have there other suspicious drivers that does not support P&P, and their names are:

ATICDSDr
atidgllk
Beep - used, could this be removed for good somehow?
BOPOMAV
c34nb4c5
DirectX DLL register
e259q4c6
Fs_Rec
rvbedit (I killed this one already)
SSDefrag (I killed this one already)
NetGroup Packet Filter Driver
Parallel - used, could this be removed for good somehow?
YQZBNWOGRK (I killed this one already)

Can I remove/uninstall few of them?
