[Solved] How to reset to default configuration in android studio

Go to your User Folder - on Windows 7/8 this would be:

[YOURDRIVE]:\Users\[your username] (ex. C:\Users\ThanhCS94\)

In this folder there should be a folder called .AndroidStudioBeta or .AndroidStudio 

Delete this folder (or better yet, move it to a backup location - so you can return it if something goes wrong).

This should reset your AS to defaults.
