A YouTube creator on the MetraByte channel attempted to install seven layers of Windows operating systems nested within each other: Windows 95 inside Windows 98, followed by Windows 2000, Windows XP, Windows Vista, Windows 7, Windows 8.1, and finally, Windows 10, all encapsulated within Windows 11. The creator initially used Hyper-V but switched to VMware after encountering limitations, allowing for more extensive layering but resulting in significant performance declines as layers increased. For example, Windows 7 took 30 minutes to boot when nested within Windows 8, which was under Windows 10, all running on Windows 11. The attempt to install Windows 95 ultimately failed as Windows 98 struggled to boot. Performance metrics showed that deeper installation layers led to decreased performance, particularly evident while playing Minecraft Classic, where frame rates dropped by over 50% in Windows 10 and 8 compared to Windows 11.
