If you want to change the default new script when you Create -> C# Script in Unity, follow the path ~\Unity\Editor\Data\Resources\ScriptTemplates and edit the text file named 81-C# Script-NewBehaviourScript.cs.txt
Note: You may need to run Notepad as an administrator if you get the ‘Access is Denied’ error message.
With the text file open, you can now edit the default new script.
I deleted the comment lines because they were unnecessary and felt too cluttered. As I get more experienced and see what functions I use frequently in a project, I can tweak it further and save some time.
