    How to See What Your Boot Up Time is in Vista

    information   Information
    To optimize the boot/shutdown of Windows, it is necessary to know precisely the reboot time of the computer to be able to refine its adjustments.
    But rather than having the hand on a stop watch at the time of the reboot, better use this easy way, You will appreciate how simple it is to use and the precision of the result.

    The relative time value will then give you a point of comparison to optimize the boot/shutdown of your computer.
    Note   Note
    For fun you can post your results here: ReBoot Time

    EXAMPLE: ReBoot-Time dialog box
    NOTE: This is what you will see after running the VB Script file from below and when you computer finishes restarting.

    Here's How:
    information   Information
    In order to calculate the time of rebooting Windows, we will use a VB Script (Visual BASIC Scripting Edition). Let us learn first how it works.

    The script writes a value in the registry (HKCU \ Software \ Microsoft \ Current Version \ run) so that it can be started again when booting. Then, another value containing the time is writen in the registry when the reboot is launched. While rebooting, the script records the hour in a variable then checks if the first value containing the time exists. If so, it is then enough to compare two times in order to obtain the time of rebooting. Then, the two keys added in the registry are removed (the run key and the key where the time is stored).

    1) Open your favorite text editor (notepad will do the job perfectly) and copy/paste the following script:

    Code:
     
    Option Explicit
    On Error Resume Next
    Dim Wsh, Time1, Time2, Result, PathFile, MsgResult, MsgA, AppName, KeyA, KeyB, TimeDiff
    MsgA = "Please close all running applications and click on OK."
    KeyA = "HKEY_CURRENT_USER\Software\RestartTime\"
    KeyB = "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run\RestartTime"
    AppName = "ReBoot-Time"
    Set Wsh = CreateObject("WScript.Shell")
    PathFile = """" & WScript.ScriptFullName & """"
    Result = wsh.RegRead(KeyA & "Times")
    if Result = "" then
    MsgResult = Msgbox (MsgA, vbOKCancel, AppName)
    If MsgResult = vbcancel then WScript.Quit
    Wsh.RegWrite KeyA & "Times", left(Time,8), "REG_SZ"
    Wsh.RegWrite KeyB, PathFile, "REG_SZ"
    Wsh.Run "cmd /c Shutdown -r -t 00", false, 0 
    else
    Wsh.RegDelete KeyA & "Times"
    Wsh.RegDelete KeyA
    Wsh.RegDelete KeyB
    TimeDiff = DateDiff("s",Result,left(Time,8))
    MsgBox "Your computer reboots in " & TimeDiff & " seconds", VbInformation, AppName
    end if
    wscript.Quit


    2) Save the file wherever you want on the same HDD (desktop for example) as ReBoot-Time.vbs (you can choose whatever name as far as the extension is ".VBS".

    You can also download the script file here:

    download < Click to Download






    Use of the Script:
    • Double click on the script icon if it is on your desktop or on the file if you saved it in a particular folder.
    • Close all the running applications and click the OK button in the dialog box.
    • The computer will reboot and when Windows will be ready to be used, a new dialog box will open displaying the time your computer took to reboot.
    Voila!

    Re: Boot Up Time

    You said that this writes a value in the registry then deletes itself from the registry after showing the Reboot Time?
    Does it just remake the registry value everytime you use it and delete itself?

    Hi McGrady,

    When you click OK to reboot, those 2 keys are added to the registry so they are available when the computer boots.
    Key A contains the time
    Key B is in "run" so the script starts again when the computer has booted
    A: HKEY_CURRENT_USER\Software\RestartTime\
    B: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run\RestartTime

    At the end, the script calculates the difference between the 2 "times" and deletes the 2 keys.

    So every time you use the script, it does it again and again.

    Hi bmb and welcome to the Vista forums!

    If you do not want it anymore, just put the script in the bin.
    The registry entries are automatically deleted when the script has finished its job
