Respected People of the Solidworks Community, Hello. This is my first post.
The problem is that when I open a New Blank Part, its not blank. Instead it has the image of an .stl file i worked on recently. the same thing happens in assembly too.

The only option i have is to delete the two STL Graphics from the feature manager and then work. But the real problem arise when I import a geometry, it has these two STL Graphics attached to it which I'm unable to delete. I also tried reinstalling the software but the same thing happens because, some files of the software remains in the system even after I delete it.

Please, Please Help. Ive attached the screenshot.

Thanks in advance.
