It shows that people have not run Windowsblinds 5. Rhey have run a older version which did use resources.
As i have said numerous times. WB5 DOES NOT USE any resources. Now it just replaces the UXTheme at startup. It only shows a Icon in the taskbar so that you can change skins when you wish. It is not even on your task manager.
As you see here. There is no Windowsblinds task running.As you can see i currently have it on this system running the Zelda theme. This is a old system that has only 512MB RAM. PC 2700 DDR with a Celeron 2.6 GHz CPU. If it doesnt slow down this system it wont slow down any others.
