Now open a command prompt with admin rights and run the following commands:
For boot tracing:
xbootmgr -trace boot -traceFlags BASE+CSWITCH+DRIVERS+POWER -resultPath C:\TEMP
For shutdown tracing:
xbootmgr -trace shutdown -noPrepReboot -traceFlags BASE+CSWITCH+DRIVERS+POWER -resultPath C:\TEMP
xbootmgr -trace standby -traceFlags BASE+CSWITCH+DRIVERS+POWER -resultPath C:\TEMP
xbootmgr -trace hibernate -traceFlags BASE+CSWITCH+DRIVERS+POWER -resultPath C:\TEMP
replace C:\TEMP with any temp directory on your machine as necessary to store the output files
All of these will shutdown, hibernate, or standby your box, and then reboot to finish tracing. Once Vista/Server 2008(R2) or Windows 7 does reboot, log back in as necessary and once the countdown timer finishes, you should now have some tracing files in C:\TEMP. If asked, upload or provide the file(s) generated in C:\TEMP (or the directory you chose) on a download share for analysis.
Analyses of the boot trace:
To start create a summary xml file, run this command (replace the name with the name of your etl file)
xperf /tti -i boot_BASE+CSWITCH+DRIVERS+POWER_1.etl -o summary_boot.xml -a boot
Now you see this picture.:
You have too look at the timing node. All time values are in ms.
The value timing bootDoneViaExplorer shows the time, Windows needs to boot to the desktop.
The value bootDoneViaPostBoot is the time (+10s idle detection) which Windows needs to boot completly after finishing all startup applications.
During the OSLoader phase (shown in the value osLoaderDuration), the Windows loader binary (Winload.exe) loads essential system drivers that are required to read minimal data from the disk and initializes the system to the point where the Windows kernel can begin execution. When the kernel starts to run, the loader loads into memory the system registry hive and additional drivers that are marked as BOOT_START.
This phase begins approximately when the BIOS splash and diagnostic screens are cleared and ends approximately when the “Loading Windows” splash screen appears.
those values show you a summary.
