All of the EmEditor features are available. The launch and operation speed is the highest. You may encounter problems with other installed applications while installing or uninstalling the program.
Installation is not necessary, because there is no read and write to the registry. It is safe to use as long as you save the data the INI file. But the launch and operating speed is slower than the Installer version.
This version is a UWP (Universal Windows Platform) app, which means that it runs within its app container and does not make changes to the registry. The speed is the same to that of the installer version. This store app version can only be installed on Windows 10, and is downloaded from the Microsoft Store (64-bit or 32-bit).
