I think (I may be wrong about what you are wanting) what you want is in the
Folder Options located in the Control Panel.
VIEW tab >> uncheck Show pop-up description for folder and desktop items
Is it a small window? Rectangular with a light border? These are "infotips"
or "comments." You can turn most of them off using various settings:
Control Panel (classic view)>Folder Options> View. Uncheck the following:
-display file size information in folder tips
-show pop-up description for folders and desktop items
For shortcuts or other files that display a comment, right click and select
Properties. If the "Comment" section is accessible, remove the text from it
using the delete and/or backspace key. Then click OK.
