Trivia

 * Windows 8, 8.1, 10 and 10.1 users can upgrade to Windows 11. If Windows 7 users want to upgrade to 11, they will have to upgrade to a qualifying operating system then upgrade to Windows 11.
 * Windows 11 Pro and Windows 11 Pro for Workstations have 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)
