Here is a SHORT list of Windows 8 features you might/should care about:
- A new authentication system lets uses draw their own custom patern on the (touch) screen as an alternative to using a password.
- Windows To Go lets you run Windows 8 from a USB stick
- Windows 8 will work on an ARM chip (i.e. Cell phone chip) (see video below)
- Win8 supports using your Live/Hotmail/Passport account for local authenication
- If you have more than one screen you use different background wallpapers for each screen
- Windows Reset will wipe your PC back to fresh install state (i.e. clean the OS and dump apps and data)
- Windows Refresh will replace system files with fresh ones and keep all your data and programs
- Windows 8 has a new service start up type called ON DEMAND which allows Windows to boot much faster and use less memory because few programs startup on boot
- Windows Explorer uses the Office 2007/10 Ribbon Interface
- Windows 8 uses the new “Metro” interface which involves tiles rather than a Start Button like, Windows Mobile 7
- ISO’s can be mounted like hard drives
- Task Manager has been seriously improved with a much simplified default view for Ending Tasks, and an advanced view which now displays much more information in a a much clearer format. I could put up screen shots but THIS GUY already did a pretty good job.
- Windows 8 will use LESS system resources than Windows 7 http://www.urtech.ca/2011/10/why-windows-8-uses-so-much-less-memory-than-windows-7/
- Sick of Adobe Acrobat… good you don’t need it anymore because a PDF viewer is built into Windows 8
- There is a Windows Store built in for buying apps directly from a trusted source
- Windows 8 Server supports live syncing to a replica server with HyperV virtualization WITHOUT requiring Windows clustering services (see the bottom video)
