Did the services.msc work? I don't understand what you mean by "Window Manager Session Manager",
go to Control Panel - Personalisation or Right Click on Desktop - Personalization.
And change it to your liking.
Colour Transparency and Intensity is related to how transparent it is (no glass).
Show Colour Mixer changes the colours.
You may also need to go to Control Panel - System - Advanced System Settings - Under Performance click Settings, adjust for Best Appearance or adjust it how you like.
