a new desktop environment

The CoreGUI project is built for servers and people who require an alternative to Windows' explorer. Accurately named CoreGUI is fully compatible from Windows Server 2003 all the way up to the latest and greatest Windows 10/Server 2019 (inc Core versions)

CoreGUI is entirely free and likely always will be. Here's what you'll need to run it:

OS: Windows XP/2003 or newer/Any Linux distro with WINE support
Processor: Pentium 2 450MHz or faster recommended
GPU: NVidia GeForce 2 MX/MX400 or newer required for visual effects
RAM: 48MB minimum
Disk Space: 30MB
