I've recompiled Notepad++ for Windows RT. I've labelled it with an 'a' because this isn't the same revision that the Win32 6.5.3 uses (it's a bit later). You will also need to install the Visual C++ 2013 runtime (get vcredist_arm.exe) because this is compiled using VS2013.
XDA Developers was founded by developers, for developers. It is now a valuable resource for people who want to make the most of their mobile devices, from customizing the look and feel to adding new functionality. Are you a developer?
