How to See What Your Boot Up Time is in Vista
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
  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
  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 in a ZIP file:

< 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?

Re: Boot Up Time

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.

Re: Boot Up Time

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
