Visually, the MainPathBoot phase begins when the “Starting Windows” splash screen appears and lasts until the desktop appears. Each subphase has unique characteristics and performance vulnerabilities. To simplify analysis, we divide the MainPathBoot phase into four subphases, as show in the next picture. This phase involves kernel initialization, Plug and Play activity, service start, logon, and Explorer (desktop) initialization.
This phase begins approximately when the BIOS splash and diagnostic screens are cleared and ends approximately when the “Loading Windows” splash screen appears.ĭuring the MainPathBoot phase, most of the operating system work occurs.

When the kernel starts to run, the loader loads into memory the system registry hive and additional drivers that are marked as BOOT_START. The value bootDoneViaPostBoot is the time (+10s idle detection) which Windows needs to boot completly after finishing all startup applications.ĭuring 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. The value timing bootDoneViaExplorer shows the time, Windows needs to boot to the desktop. Xperf /tti -i boot_BASE+CSWITCH+DRIVERS+POWER_1.etl -o summary_boot.xml -a boot To start create a summary xml file, run this command (replace the name with the name of your etl file)

If asked, upload or provide the file(s) generated in C:\TEMP (or the directory you chose) on a download share for analysis.

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. Replace C:\TEMP with any temp directory on your machine as necessary to store the output filesĪll of these will shutdown, hibernate, or standby your box, and then reboot to finish tracing. Xbootmgr -trace hibernate -traceFlags BASE+CSWITCH+DRIVERS+POWER -resultPath C:\TEMP Xbootmgr -trace standby -traceFlags BASE+CSWITCH+DRIVERS+POWER -resultPath C:\TEMP Xbootmgr -trace shutdown -noPrepReboot -traceFlags BASE+CSWITCH+DRIVERS+POWER -resultPath C:\TEMP I've send some dumps to Microsoft, they look at the issue right now. Xbootmgr -trace boot -traceFlags BASE+CSWITCH+POWER -resultPath C:\TEMPĪlso change the name in the command to generate the XML. If you get this, use system restore to go back to a working Windows and run the command without DRIVERS Xbootmgr -trace boot -traceFlags BASE+CSWITCH+DRIVERS+POWER -resultPath C:\TEMPĪttention: Some users reported that they get a bugcheck (BSOD) when using the DRIVERS flag in the boot trace command. Now open a command prompt with admin rights and run the following commands: To get started you need the Windows Performance Tools Kit. This is an updated tutorial of the one cluberti posted here.
