Windows Nano10 Access

Officially, Microsoft has never released a consumer product called "Windows Nano 10."

Windows Nano 10 is the Linux of the Windows world: minimalist, terrifying to configure, and blissfully fast.

It ripped out GDI (Graphics Device Interface) and replaced rendering with DirectX 12 Ultra-Lite. The OS booted to a command line in 2 seconds. With a community driver pack, it booted to a desktop in 6 seconds.

It was a failure. (At least, commercially.) And for two glorious hours, you'll wonder why
