Check this setting in the Registry:
Open The Registry Editor (type regedit into the Search Bar and press the Enter key, then click ‘Yes’ on the UAC box if it shows.
Navigate to:
Code:
Computer\HKEY_CLASSES_ROOT\SystemFileAssociations\.xlsx
When you have located the entry, click it and look in the right pane for the
Info Tip entry.
D/click and it should show this:
Code:
prop:Type;DocAuthor;DocTitle;DocSubject;DocComments;Size;Write
If any of this is missing, copy what is showing above and paste it into the ‘Value data’ field.
Check the mouse hover now.
I tested it on my system and when I remove the author and title, it doesn’t show in the mouse hover (pop-up).
Warning – you should always Backup the Registry first if any changes are made
