  1. Windows 8 The Good, the Bad, and the Ugly Presented by Peter Schepers, IST Last updated December 3, 2012

  2. Seminar Introduction • Major changes and features from Win7 • Windows 8 in a business setting • Tour the ModernUI

  3. What is Windows 8 • A single unified OS for tablet and desktop • Focus on touch, a radical shift in UI • Targeted at the mobile & home user • Integration with Microsoft cloud services • Trying to compete in the mobile market against Google Android and Apple iOS • Longer battery life

  4. Windows 8 Design Goals • Always connected, content in the cloud • People, not files, are the center of activity • Live tiles, actively updated • PC works like a device, not a computer

  5. Experience with Windows 8? • How many use or have used Windows 8? • How many on proper multi-touch devices? • First use reactions?

  6. Typical First Reactions • What do I do now (once logged in) • Where is the desktop • Where is the start button • How do I shutdown or restart

  7. Hardware Requirements Almost the same as Windows 7… • CPU: needs PAE, SSE2 and NX (XD) bit* • RAM: 1Gb for 32-bit, 2Gb for 64-bit • HD: 16Gb for 32-bit, 20Gb for 64-bit • Video: DirectX 9 • Hyper-V: Intel “i” series or higher

  8. Upgrade Path • From XP: only user files • From Vista: user files and settings • From 7: programs, user files and settings

  9. Compatibility • Kernal is now 6.2 • Microsoft claims all Win7 programs & drivers will work in Win8 • Practically that’s not the case, but close

  10. Opening Quote “I love what we’re doing with Windows 8, and it’s a bold bet. We’re re-imagining our number one product. That’s cool. But it’s not for the fainthearted. It takes a certain boldness and a certain persistence.” Steve Ballmer, Microsoft CEO in a Forbes interview

  11. Counter-quote “Windows 8 is the most controversial release of Windows ever, eclipsing previous perceived disasters like Windows Vista and Windows ME.” “Windows 8 is the biggest and most confusing upgrade that Microsoft has ever wrought on its most core of platforms. It is, as I wrote... a mess. A glorious, wonderful mess.” Paul Thurrott, WinSuperSite

  12. Windows 8 Test Drive Let’s see what it looks like! • Lock screen • Login options • ModernUI • Desktop

  13. Features & Options

  14. Future: ModernUI • New Start Screen • Formerly known as “Metro” • Influenced from Zune and Windows Phone • RT apps, live tiles, Microsoft Store • No way to avoid using it • First generation UI • Poor integration with desktop

  15. Feature: Windows-To-Go • Configures a deployment image on a key or USB drive (32Gb min, USB3 preferred) • System needs to be configured to allow USB booting • Boots on other hardware, device detection • USB drive should be cooled • Can’t use MAK activation • Microsoft Store access disabled • Local hard disks offline • Possibly useful for data recovery scenarios

  16. Feature: Client Hyper-V • No more Virtual PC or Windows XP mode • Now a layer 1 (bare metal) implementation • Need to enable it • Fully functional only on a 64-bit OS • Needs virtualization enabled in BIOS (no TxT) • Requires a CPU with SLAT (“i” series+)

  17. Feature: Refresh/Reset Your PC • Under Charms/PC Settings/General • Both required the DVD on imaged systems • Refresh retains user RT apps and data, but programs need to be re-installed • Reset restores system to factory

  18. Improved: Task Manager • Simple view is a task switcher/killer • Full view is powerful • “Heat sensitive” view • User apps and system tasks are separated

  19. Improved: Fast Boot/Restart • About 50% faster • Kernal/drivers are “hibernated” during shutdown • F8 “boot options” menu no longer functions

  20. Feature: ISO & VHD Support • Both mount as a virtual device • Can install software from ISO • Mount VHD and move data in/out

  21. Improved: File Copy • All copy/move/delete operations are combined on this new window • Can pause an operation • Bar graph showing transfer speed

  22. File Copy

  23. Improved: Security • Includes AV & malware • UEFI booting for OS signing and boot file verification (to prevent rootkits) • UEFI enabled prevents XP and Linux booting • RT apps are sandboxed • DLL’s load at random locations • Uses the CPU NX setting to prevent malware execution • IE has Do-Not-Track enabled

  24. Feature: USB3, 3G/4G Support • Has native USB3 drivers, faster • Native support and drivers for mobile broadband • Airplane mode • Metered connections

  25. Feature: Storage Spaces • Basically a software RAID system • Combine many different drives into 1 large • Thin provisioning

  26. Feature: File History • Saves to a different drive (USB, network, other hard disk) • Replaces “Previous versions” • Not enabled by default

  27. Removed: Aero • Most of the desktop eye candy is gone • Removed due to power requirements • Does make the windows seem bland

  28. Goal: Battery Life • Tickless and streamlined kernal • Aero removed • Going for long battery life on mobile

  29. Removed: Start Button • Now a “power menu” and the Start Screen icon • Shutdown/Restart now in different places • Most things it contained exist elsewhere • Many third party replacements available: • Start 8 • ViStart • Classic Shell • Start Menu X, Pokki, Win8Start Button, StartMenu

  30. Troubleshooting • F8 boot menu gone, so how do we fix a system that won’t boot? • Blue screens are less informative • Improved Task Manager • Windows-to-Go offlines local hard disks

  31. Blue Screen Error

  32. Personal Usability Notes • No IE 10 Favorites redirection • Didn’t get my desktop back • Default file associations are mostly to ModernUI apps • .NET 2.0/3.0 not enabled/installed • Hyper-V not enabled/installed • SMB required registry hack

  33. Conclusions: The Good (1) • Fast & stable • Should work good on the right touch hardware • Greater battery life • Hyper-V is great! • VHD and ISO mounting • Multiple screen support • Security improvements • Power menu

  34. Conclusions: The Good (2) • Most programs and drivers from Win7 work fine • Boot & login speed • RT movie player • Microsoft store • Deployment similar to Win7 • Updated WinPE4 (+USB3) using DISM

  35. Conclusions: The Bad (1) • No “must have” feature except Hyper-V • No way to avoid ModernUI (Start Screen) • Many file associations to RT apps • Will require much training and patience • IE 10 unreliable • Window status bar dumbed down

  36. Conclusions: The Bad (2) • No local UW RT app to show off • Can’t use the MS integration here • Refresh/Reset not useful, imaging better

  37. Conclusions: The Ugly • SMB defaults to strict for our SMB • DVD playback removed • No Start Button for desktop users • F8 troubleshooting boot option gone • Can’t easily boot straight to desktop • Forcibly switched between desktop, ModernUI apps and Start Screen • Business (desktop) systems are non-touch

  38. Conclusions for UW • So what’s the point of deploying? • Windows 7 still has many years ahead of it • Maybe Microsoft will see the light, the error of their ways…

  39. Closing Quotes “Windows 8 is not a productivity OS. It is lots of eye candy and has no place in the business world. That will become evident quickly. Using it for business will be like trying to pound a square peg into a round hole. You may succeed, but it will be hard, messy, and cause a lot of damage.” online user
