Windows 10: How To Increase TaskBar ToolTip Character Amount

Hello, I've heard from before that you can increase the amount of characters shown in a ToolTip from a System Tray Icon. As you can see in the attached picture that this information shown is not complete (it cuts out halfway in the third email listed, yet there are currently 5 emails total). I want it to show all the text information that the ToolTip is intending to show. Does anyone know the Registry modification that I need to do to fix this? Thanks

Edwin: I see. I looked in my app, too bad it doesn't have any settings to adjust that info. =/

lx07: Thanks for the reference to that site! I was looking for that a while back, and now you found it for me. What's really strange though is I remember when Windows 10 first came out, this limit did not exist (or most likely had a much bigger limit) because I was able to see all my emails. The thing about it is that it doesn't spam everything about the email Subjects. As you can see in my attached picture above, the end of the line of the first email shows "...", so it doesn't end up taking too much space/characters. I just hope this email notifier had more settings to it, maybe an alternate notification window that isn't Windows related. Maybe in the future, maybe I can ask the developer.

LMiller7: "The 200 characters mentioned is I believe only a recommendation and not an imposed limit."
Yes, I thought that is true too. But I see what you mean. Maybe the developer did that 5 line max setting after all the updates.

The app is called Howard E-Mail Notifier. It's only a little tiny app that shows you how many new emails you have in your email account. So if I left click on that icon, it will open Google Chrome and go to my Windows Hotmail account within the browser. I don't use an external app for my email account.
