Your Mouse Hover time in the Registry is set to Default, it is just the same as mine. 400
Maybe I am not understanding your questions? If your mouse gets Stuck for a spit second, you may call it a hover, then this is usually an issue with some software you've installed. A Clean Boot will usually fix this issue.
If you have slow internet, your mouse may hover for split second before moving on. Testing your internet speed takes just a few minutes.
If I am misunderstanding, then maybe someone else can chime in?
