Notepad++ is a free text and source code editor for Windows systems. Additional plugin support from third-party developers has made it a popular code editor for programmers. That said, several users have reported the Notepad++ not responding issue when using the code editor.

Your Notepad++ may stop responding if a third-party plugin is causing an issue. However, the issue can also be due to previous sessions.

Notepad++ developers recommend using the two-line argument that allows you to start Notepad++ without loading the previous session or plugins, making it easier to determine the cause of the problem with Notepad++.

In this article, we take a look at the best solutions to fix the Notepad++ not responding issue on Windows.

What to do if Notepad++ is not responding?

1. Start Notepad++ without plugin and previous sessions

-Nosession – This command-line argument starts Notepad++ without loading the previous session. So, if you think Notepad++ is crashing due to the previous session, try loading the tool without the previous sessions.
