Windows Size/Location Cache

I've been using CCleaner for many years and I'm using the lastest version. I don't think the option to clear windows size/location cache is working. I thought that it used to work. The option is checked in CCleaner. I do a clean, but when I open a folder in Windows Explorer, it has not been reset to it's default size or location. I'm using Window 7 64bit.

Thank you for the help.
