Notepad++ is a powerful text editor; so much more than a Windows Notepad replacement, and (for me at least) often better for 'real' word processing than Microsoft Word, when coupled with language tools (like Markdown) and plugins.
One of the powerful features in Notepad++ is the Plugin Manager, which provides an easy check-box menu system to install a wide array of plugins that enhance the program. This way, you don't have to mess around with finding and downloading add-ons - it's easy to get them right from the application.
I've noticed a nuisance though, in that the Plugin Manager can get corrupted, and it starts complaining when the application starts up with a message like this:
Clicking 'Yes' in the above window results, ultimately, in failure:
To resolve this problem, there are three (easy!) steps:
1. Download the newest version of Notepad++ Plugin Manager to your local machine.
2. Open the downloaded zip file, and copy the
plugins folder to the Notepad++ Application folder. For my machine, that location was
C:\Program Files (x86)\Notepad++
3. Restart Notepad++
