There[SQ]s no such thing as "Manjaro KDE for Windows."

Manjaro is a Linux distribution, meaning it[SQ]s an operating system built on the Linux kernel. Windows is a completely different operating system. You can[SQ]t run Manjaro *on* Windows in the same way you might run an application. You would need to install Manjaro on a separate partition or drive, or potentially use a virtual machine (like VirtualBox or VMware) to run Manjaro *within* Windows. But that[SQ]s still running Manjaro as a separate, virtualized operating system, not as a Windows application.

KDE is a desktop environment, a graphical user interface (GUI) that runs *on top* of Linux (or other Unix-like operating systems). Manjaro KDE is simply a version of the Manjaro distribution that uses the KDE Plasma desktop environment. It has nothing to do with Windows.
