|KernelInitTimeMs||Time from the beginning to the start of the first smss.exe process||Number||ms||1683|
|SmssInitTimeMs||Time from the start of the first smss.exe process to the start of the second smss.exe process (in session 0)||Number||ms||4007|
|AutoCheckTimeMs||Auto check time. More information.||Number||ms||20|
|Session0InitDurationMs||Session 0 initialization duration: from the start of the second smss.exe process to the start of wininit.exe||Number||ms||9572|
|Session1InitDurationMs||Session 1 initialization duration: from the start of the third smss.exe process (in session 1) to the start of winlogon.exe||Number||ms||71|
|WininitInitDurationMs||Wininit initialization duration: from the start of wininit.exe to the start of services.exe||Number||ms||61|
|WinlogonInitDurationMs||Winlogon initialization duration: from the start of winlogon.exe to the start of logonui.exe||Number||ms||369|
|AutostartServicesMs||Autostart services: from the start of services.exe to the start of the first taskhost.exe||Number||ms||13269|
|ComputerStartupMs||Computer startup: from the beginning to the start of LogonUI.exe. The user is now able to log in to the computer.||Number||ms||15700|
|MainPathBootTimeMs||Main path boot time: from the beginning to the start of the shell (typically explorer.exe).
The user has successfully logged in and the shell is starting.
|PostBootTimeMs||Post boot time: from shell start to the system reaching an 80% idle state.
The desktop is now ready to use.
|TotalBootTimeMs||The time from Windows start to the desktop being shown and the system reaching an 80% idle state.
This is the sum of MainPathBootTimeMs and PostBootTimeMs. If TotalBootTimeMs is empty, it means that Windows stopped collecting data too early, or because the user waited longer before logging in.
|BootUID||Unique UID for a boot created by uberAgent||String||00000408-0049-004b-0bb9-8ed17e25d401|
