Trivia

 * Windows 11 can be upgraded from Windows 10.1, Windows 10 and Windows 8.1
 * System requirements are same from Windows 8/8.1 and Windows 10 except Windows 11 Pro for Workstations. But Windows 11 is not designed for old computers. However some old computers can run Windows 11 well.
 * Windows 11 Pro and Windows 11 Pro for Workstations has updated default apps but you can still find their original Windows 10 Pro version of these applications in other versions of Windows 11:
 * Active Directory 2.0 (more options and better design)
 * Remote Desktop 2.0 (more options, better design and even faster user change)
 * BitLocker 2.0 (there are 8-bit, 16-bit, 32-bit, 64-bit, 128-bit or 256-bit options for encryption. Microsoft might be able to develop 512-bit encryption if the technology is enough at that time. Better design.)
 * Hyper-V 2.0 (virtual machine bugs fixed and better virtual environment)
