Like others I have just registered so I can have my say on the v5.00.5050 windows 8 look GUI.
On windows 7 IT LOOKS TERIBLE and looks almost like a throw back when computers had a monochrome screen.
Why copy Microsoft's design faults of windows 8 that business as a whole has not liked and has cost Microsoft so much in lost sales.
CCleaner v5 GUI is pitiful.
I will be going back to v4 it works for me.
