Thanks for the hint !!
I used a free program but i saw to my ashtonishment a trojan in it.
Googled on it and found out that it wasn`t free of malware.
I do use winx now and will give the wise program a try too.
It will clean your registry but altering your manually settings too.
Every time i clean with this program i have to alter manually my settings again.
(auslogic bootspeed does the same)
