    Windows boot time variance


    Not really a problem to be solved (I think) but I like to know how things work.
    I have clean system and the usual boot up time is 30 seconds or less.

    Sometimes for reasons I do not know, it takes 2 or 3 minutes, but back to normal next time without me doing anything in particular.

    Why?

    Hello @Passenger Chi,

    Just for informational purposes, if you are interested in Boot information, then Copy & Paste the following [ ALL at once ] into a CMD Prompt and press Enter. You are probably interested in ID=27:

    The below [Kernel-Boot ID=27] options [Within Message] are available:

    - 0x0 = Cold Boot from FULL Shutdown or Restart.
    - 0x1 = Hybrid Boot [Fast Startup].
    - 0x2 = Resume from Hibernation.

    Code:
    
    @echo off
    echo.
    PowerShell ^
         $Tot=((Get-WinEvent -ProviderName Microsoft-Windows-Kernel-Boot -ErrorAction 'SilentlyContinue') ^| Measure-Object).Count; ^
         $List=(Get-WinEvent -ProviderName Microsoft-Windows-Kernel-Boot -ErrorAction 'SilentlyContinue'  ^| Sort-Object -Property TimeCreated -Descending ^| Format-Table -Wrap -AutoSize ^
         @{L='Level Display Name';E={;if([string]::IsNullOrWhiteSpace($_.LevelDisplayName)) {'-'} else {$_.LevelDisplayName}}}, ^
         @{L='ID'                ;E={;if([string]::IsNullOrWhiteSpace($_.Id))               {'-'} else {$_.Id}}}, ^
         @{L='Record ID'         ;E={;if([string]::IsNullOrWhiteSpace($_.RecordID))         {'-'} else {$_.RecordID}}}, ^
         @{L='Time Created'      ;E={;if([string]::IsNullOrWhiteSpace($_.TimeCreated))      {'-'} else {$_.TimeCreated}}}, ^
         @{L='Message'           ;E={;if([string]::IsNullOrWhiteSpace($_.Message))          {'-'} else {$_.Message}}} ^| ^
    Out-String -Width 166).Trim("""`r`n"""); ^
         if ($List.Length) {Write-Host """`n `n--- WinEvent(s) --- Kernel-Boot [ALL] --- Total = $Tot --- Sorted by [TimeCreated -Descending] ---`n`n `n`n$List"""} else ^
                           {Write-Host """`n `n--- NO WinEvent(s) --- Kernel-Boot [ALL] Available ---"""; exit 1} >> %Temp%\A.txt
         for /f "delims=" %i in (%Temp%\A.txt) do echo. %i
         del %Temp%\A.txt & echo. & echo ^>Press ANY key to EXIT . . . & pause >nul & Exit
    
    
    

    If you JUST want the output to show ID=27, then let me know and I will post the commands for you.

    I hope this helps.

    In addition to Windows updates there maybe indexing, virus/malware scans, disc optimisation, time syncing, applications scanning for updates etc, etc.
