wrong case is showing

i have a network drive which is z:. i have a folder called movies in it and i have a movie which is called kiki's delivery service.mp4 and all the letters are in lower case

if i search for the movie in the windows start menu then it is showing in upper case and it's Kiki's Delivery Service as you can see in this picture:-


the problem is that i am unable to make it show all lower case in the search. if i change the file name then the new file name shows in the search and it's all lower case but if i put back the file name to as it was before then it goes back to upper case

i also have the same movie folder on an external hard disk and if i do a search for the movie on the external hard disk in the start menu then it is also showing in upper case. however, if i copied the file to my laptop hard disk and do a search for the movie on the laptop hard disk in the start menu then it shows in lower case. i also connected my external hard disk to another laptop and i did search for the movie in the start menu and it showed in lower case

what's going on and why is it insisting on upper case?

Hey bud

Okies im not entirely sure how to fix this. Could it not be some sort of software association problem?
Like do you have VLC installed on all the other machines? Maybe try and have a clean up of any old media software. I used to like Glary Utilities. It was always good at removing any old file associations and left over crap in the registry.

Sorry i cant help anymore. Hopefully someone on here will have a decent explanation as to whats going on.
