Windows 10: I accidentally made it so that notepad always opens for .frag files.

I accidentally made it so that notepad always opens for .frag files, but when i went to change it by using "Choose default apps by file type" in the settings, i only got two options: Notepad which i do not want, or search in the Microsoft Store which has nothing that helps. I have multiple other apps that all appeared when i accidentally clicked to always use notepad, but now they seem to be gone from the list, and its only those two..

Rar files opening in Notepad

I play games such as Sims 4 and I download custom content. A good portion of the stuff I download are RAR files. I accidentally clicked "Always open with notepad" and I can no longer get it to be just a normal file. I would like to know how to make it not open as a notepad file/in notepad. Please help!

 

Notepad Opening File Complications

While I was downloading something I received the option to use Notepad to help download a mod for a game of mine, I accidentally clicked the "open all files using Notepad" option, which, every time I open apps it opens with Notepad which doesn't let me
use the app but shows the coding or words and numbers. I deleted notepad trying to stop the files from opening like that but it seems to still be opening like this. How do I get my apps and files to work normally again and stop notepad from opening all my
files.

 

.exe files opening in notepad

Hey, I was just trying to download a .exe file the other day, and accidentally clicked an option that made it so that every file I now open is opened with notepad. If there is any way to fix this, I would be very happy. Thanks.
