As we’ve known for some time, Microsoft had already begun work on Windows 8 before Windows 7 was completed. The reason being that different teams work on different aspects of the operating system, which is why Microsoft was able to do this. Microsoft previously shed some light on what we can see in Windows 8 through a job description.

It appears though, that one specific Microsoft employee was not too
careful with their LinkedIn profile, and had accidentally leaked some
interesting details regarding Windows 8. According to his LinkedIn
profile, which seems to have had many of its details removed, Robert Murdon has been working at Microsoft since January 2002. Windows 8 News managed to catch this on the Microsoft employee’s LinkedIn profile before it disappeared:

"Robert Morgan is working to get IA-128 working backwards
with full binary compatibility on the existing IA-64 instructions in
the hardware simulation to work for Windows 8 and definitely Windows 9.”

"Robert Morgan is using Hestia (custom software package) for
experimenting with the processor for scientific analysis and 3D
graphics. Error: Memory Latency? Always gotta be a challenge barrier,
it’s gotta be a bug in Hestia. right?!”

"Robert Morgan is frustrated with process standards and regulations! Delays Delays!”
