MUI problem,help me fix it! problem, MUI, fix, help

i still have problem with this MUI , i try to use Bitlocker ,if i can use this it should be nice ,cus i can lock my drive safely. don't want anyone to touch my drive or docs inside. that is why i need to lock it.

adding to more problem , now my window 7 get slower than before (shutdown) it takes about 1 to 2 mn to shutdown ,that is what i can wait. though i already changed some Registry ,but it still the same , it seems time to kill app ,service all shutdown very fast but after that it displays " shutting down" and that is the time i need to wait....can't find the way out,so now change to use Kubuntu...cool
