Microsoft for use on personal computers, including
home and business desktops, laptops, tablets, and
home theater PCs.

4.  Development of this operating system started before
the release of its predecessor in 2009.
 Its existence was first announced in January 2011 at
Consumer Electronics Show.
 During its development and test phases, Microsoft
released three pre-release versions:

 Release Preview (May 31, 2012)

5.  On August 1, 2012, Windows 8 graduated from the
development stage and was released to
manufacturing.
 Windows 8 is scheduled for general availability on
October 26, 2012
 Windows 8 introduces significant changes to the
operating system's graphical user interface and
platform, such as a new interface design
incorporating a new design language used by other
Microsoft products, a new Start screen to replace the
Start menu used by previous versions of Windows

6.  Additional security features in Windows 8 include
two new authentication methods tailored towards
touchscreens (PINs and picture passwords),the
addition of antivirus capabilities to Windows
Defender (bringing it in parity with
Microsoft's Security Essentials software)Smart
Screen filtering integrated into the desktop.
 Windows 8 also provides integrated system
recovery through the new "Refresh" and "Reset"
functions , including system recovery from USB
drive.

8.  The three desktop editions of Windows 8 are sold in
two sub-editions: 32-bit and 64-bit.
 The 32-bit sub-edition runs on CPUs compatible
with x86 architecture 3rd generation or newer, and
can run 32-bit.

BitLocker upgrades (to pro!)
Secure Boot controversy
Microsoft Sign-In

14.  Secure boot is a UEFI-based feature to "prevent
unauthorized firmware, operating systems, or UEFI
drivers from running at boot time".
 Hardware makers who choose the optional
Microsoft Certification will be required to
implement UEFI.
 The bottom line is that it will require bios changes
to install a 3rd party OS like Linux on any PC that
has windows 8 pre-installed with the Microsoft
certification.
