Reset package like new

Hello, i have many package atom and its causes atom so slow ( it takes 180 sec to opened it by timecop ). So i want to reset the package that only package by atom is active, but not remove third party package.

I can do this manually by deactive third part package, but idk which package is third party or not. Thanks anyway

https://github.com/atom/atom/tree/master/packages You can check the README to see the Atom Core Packages.
Another way of doing it is to delete D:\Users\your-user.atom\packages contents, but that will remove any installed package that is not ATOM core package.

thx i already did it by disable all package which not core package
