System Uptime on Windows10

I was looking for a way to find out how long my PC had been running a few weeks ago and had trouble finding something that satisfied my needs,  I found a Visual Basic Script that worked but found it too long. But searching trough AutoIt WINAPI help found that it really was as simple as the following little script.

#include <WinAPISys.au3>
#include <WinAPIMisc.au3>

Local $Uptime = _WinAPI_StrFromTimeInterval(_WinAPI_GetTickCount())
MsgBox(0, '', "PC Uptime ==> " & $UpTime)

Hope it helps...

Welcome ces1a,

That is a very quick and useful way to get the uptime, yes.  I hadn't come across that method before; however, reading the verbiage on the _GetTick function from the help file, this method will be unreliable if the machine is "up" for longer than ~48+ days.  The help article also suggests using probing the system uptime counter from performance data...another way I've not done (or seen). 

Sure, the likely hood of a Windows machine being online that long is pretty low (if it is patched monthly), but it might be worth while thinking about these limitations and consider how you would address those limitations if necessary.


An alternative approach, which I have seen and used, is to collect the system boot time and calculate the duration from "now".  Here's an old(er) link to some examples. ;) https://www.autoitscript.com/forum/topic/110300-system-uptime/#comment-774837

I'm not trying to critique too harshly...I just noticed this is your first post and wanted to expand your knowledge in case you weren't aware or didn't think about it.  Once again welcome.

 

edit: to be fair...I have not tested those examples on Win 10 or verified they work with the latest ver(s) of AutoIt.  I just wanted to provide some more code for you to check out.

You are right about the limitations of the method but if you modify it as follows it works.

#include <WinAPISys.au3>
#include <WinAPIMisc.au3>

Local $Uptime = _WinAPI_StrFromTimeInterval(_WinAPI_GetTickCount64())
MsgBox(0, '', "PC Uptime ==> " & $UpTime)

 

The only difference is the line: 

   Local $Uptime = _WinAPI_StrFromTimeInterval(_WinAPI_GetTickCount())

Is changed to:

    Local $Uptime = _WinAPI_StrFromTimeInterval(_WinAPI_GetTickCount64())

Thanks for your input.

Good info here. Thanks!

There is a really easy command for this.

In command prompt, type "net statistics workstation" and press enter. You will see "Statistics since <DatePCStarted> <TimePCStarted>" at the top which essentially tells you when you started your computer.

 

btw, you can just press windows key + r (run dialog) and type "cmd /k net statistics workstation" for the same effect. the /k flag tells cmd to remain open and accept new commands once the command is processed. Optionally, you can do "cmd /c pause | net statistics workstation" instead if you don't want cmd to accept new commands but still remain open. Note Pause must be first entry or it won't actually pause.

Thanks for the info, BetaLeaf, but what I needed in my case is to run a program when my computer starts.

The program has to wait 3 minutes from the time the laptop started to run two programs so as not to slow Windows startup in any way.

Getting the System Uptime had to take place automatically.  This way when the computer has been running close to three minutes my script runs two of my other programs.

Put a 3 minute delay at the start of the script you're running, that way no matter when it starts running the rest of the script won't do anything until 3 minutes later.

If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

      Script acting weird at startup
      By spuuunit
      I have a script that autostart with Windows, and sometimes some of my code is skipped. My script takes long pauses, so it's not that the script "goes too fast". This is my script for now:
      TraySetIcon("C:\Portables\AutoIt\_\icon.ico") AutoItSetOption("WinTitleMatchMode", 2) Run("C:\Portables\Key Manager\keymanager.exe") WinActivate("ATNSOFT Key Manager v") WinWaitActive("ATNSOFT Key Manager v") WinMove("ATNSOFT Key Manager v", "", 650, 200, 600, 800) Sleep(500) $pos = MouseGetPos() MouseClick("left", 1220, 210, 1, 100) MouseMove($pos[0], $pos[1], 100) Run("C:\Portables\foobar2000\foobar2000.exe") $version = 298 For $i = 0 To 99 Step 1 $path = "C:\Users\spunit\AppData\Local\Discord\app-0.0." & $version + $i & "\Discord.exe" If FileExists($path) Then Run($path) ExitLoop EndIf Next Run("C:\Portables\Firefox\FirefoxPortable.exe") Sleep(10000) WinMove("- Mozilla Firefox", "", 205, 0, 1214, 1047) Sleep(100) MouseClick("left", 1300, 15, 1, 10) Sleep(100) MouseClick("left", 1130, 275, 1, 10) Sleep(100) MouseClick("left", 930, 105, 1, 10) Sleep(100) Send("#{m}") Sometimes it skips to click and move mouse right after Key Manager starts. Almost always it skips everything after the last run.

      This type of script were never an issue with Windows 7... Any thoughts?

      How to find if window handle is active on current virtual desktop (Win10)
      By DLS
      I have a working script that changes the core affinity and process priority of multiples of a specific application I have running.  
      I have that part figured out.

      I would like to make a little modification to it.

      Windows10 introduced virtual desktops.  I am trying to have different core affinity and priority of processes on the visible and non-visible desktops.  
      What I need is a bool function that could be described as IsWindowOnCurrentDesktop($hWnd).  I have searched the winAPI.au3 but I do not believe anything like that exists built it.
      I have searched multiple places before asking for help. I found a Microsoft supplied example of the function I need using C#, but I am unfamiliar with C# to a degree that I cannot port the system call over.
      https://blogs.msdn.microsoft.com/winsdk/2015/09/10/virtual-desktop-switching-in-windows-10/
      Help is appreciated but not expected.  Thanks in advanced.   In the meantime I will be learning C# syntax and class structure.

      SecondsAfterLogin

      Hi,
      after I recognized that some of my scripts fail if they are at windows startup I researched for a solution. Problem could be fixed if I wait about 120 seconds after login. So how to measure this?

      help with retrieving system info
      By nss
      Hi all,
       
      I'm making an app that among other things has the system info feature, where it displays stuff like the system version, build, CPU and ram stats, etc.
      So, I haven't been able to find anywhere a way to access the following things (is there even?):
      Windows version (not like WIN_10, but the version like 1607, or 1511 Windows edition like professional, home, education, etc. information whether the Windows is registered or not (optionally the registrant's name) the type of the currently logged-in user (e.g., administrator) computer manufacturer and model (e.g., dell inc. Inspiron n5110 boot mode (e.g., safe, normal) CPU tempreture I'd appreciate a lot if any of you could help me with any of the things from above; it would mean a lot to me.
       
      Have a great day.
