First introduced in the ReactOS 0.4.5 release, the support for styles created for Microsoft’s Windows XP operating system received further enhancements in ReactOS 0.4.7 to reduce visual glitches for several apps, as well as to better handle transparency and messaging. ReactOS 0.4.7 also implements support for Shell extension and allows users to enable the Quick Launch shell extension manually if they want an early taste of this feature. Furthermore, the devs managed to bring the ReactOS painting process closer to the one of the Microsoft Windows OS.
