Agenda

• What is reliability?
• Development of Microsoft Windows Vista
• Processes implemented for more reliability
• Improvements in reliability and performance

What is reliability?
4
Windows Error Reporting data

• On the top Top 100 reported crashes
• 5 is because of Microsoft software (And yes, we
  are working on it)
• 10 because of problems with the hardware
• 15 Unknown (Memory dump too corrupt)
• Pool corruption
• Memory Corruption
• 70 because of 3rd party code
• Didnt understand documentation
• Problems with the Tools
• Just Old Bugs In Code
• Data from Microsoft Error Reporting as
  mentioned in Windows Sysinternals Book.

5
For the customers point of viewReliability is
more that a hang or crash
Many Factors Impact Perceived Reliability

• Restarts, shutdowns
• Downtime
• Maturity of Operating System
• Rebuilds, reformats
• Software wont run
• Data loss

• Bugs, errors, faults
• Application crashes
• Blue screens
• Patches, hot fixes
• Stability, predictability
• Freezes, hangs

Focus on Reducing User Disruptions

• Measurably lower the number of hangs, crashes and
  reboots
• while reducing disruptions from planned
  activities such as software installations

Reduce Loss of Work, Time, Data, and Control

11
Improve the reliability

• VGA driver taken out of the Kernel
• New driver model Windows Display Driver Model
  (WDDM)
• No more painting with windows (Unless you have a
  XDDM driver)
• Windows Diagnostic Infrastructure (WDI)
• Detect Memory Leaks
• Detect Deadlocks
• Synchronous Cancellation of I/O requests
• Extended reporting with feedback loop
• Protection of the registry, system folders

12
Windows Resource Protection

• New in Windows Vista
• Replaces the existing Windows File Protection
• WFP Only protected .dll, .exe, .ocx, and .sys
  files (and Micross.ttf, Tahoma.ttf, Tahomabd.ttf)
• Windows Resource Protection protects more files1,
  system folders and the registry
• Updates Only allowed via the Windows Trusted
  Installer

1) If installed these extensions are protected by
the Windows Resource Protection service .dll,
.exe, .ocx, .sys, .acm, .ade, .adp, .app, .asa,
.asp, .aspx, .ax, .bas, .bat, .bin, .cer, .chm,
.clb, .cmd, .cnt, .cnv, .com, .cpl, .cpx, .crt,

13
Improve the reliability

• Restart Manager (aka. Freeze Dry)
• Restarts applications that need to be patched
• Shadow Volume Copy
• Now also for the client PC, Set via GPO
• Disk Quota
• Now also for the client PC, Set via GPOs
• Backup capabilities

14
Improve the reliability

• Resource Exchaustion
• Harddisk Failure
• Shadow Volume Copy
• Synchronous Cancellation of I/O requests

15
Improving the performance

• Improve the responsiveness of the system
• Also after working for 3 months with the PC
• Enhanced help and support
• Monitors the PC startup and shutdown
• Gives advice and details
• TCP/IP Variable Packet Size

16
Improving the performance

• ReadyBoost
• More performance by using USB flash disks for
  caching
• USB 2.0 Flash Drives, SD Cards, CF cards
• Must be at least 512Mb and fast enough
• Data is encrypted and copied to the harddisk
• Can be unplugged at any time
• Not used as more internal memory (RAM)

17
Improving the performance

• ReadyDrive
• Harddisk with extra Flash memory onboard
• Hybrid Harddisk
• Writes data to Flash memory instead of the HDD
• Writes Hibernation file to Flash instead of the
  HDD

18
Improving the performance

• SuperFetch
• Optimalisation of Memory Management
• Different level for User applications and
  Background applications (High Priority I/O vs.
  Low Priority I/O)
• Optimalisation of internal memory after running
  Background processes
• Monitor most frequently used applications and
  anticipates
• I/O levels prevents Competing I/O

19
Improving the performance

• ReadyBoost
• Monitoring of the PC startup and shutdown
• Power Off Experience

20
Give more information and make it manageable for
the IT Professional
