Время непрерывной работы Windows с момента последней перезагрузки (uptime) можно узнать разными способами.
В графическом интерфейсе общее время работы Windows можно найти в диспетчере задач.
- Запустите Task Manager (выполните команды
taskmgr.exe
или нажмите сочетание клавиш
Ctrl+Shift+Esc
) - Перейдите на вкладку Производительность (Performance) -> вкладка ЦП (CPU)
- Время непрерывной работы компьютера содержится в поле Up time
-
Также можно получить текущий uptime из командной строки. Выполните команду:
Systeminfo
Время последней загрузки (перезагрузки) Windows указано в значении System Boot Time.
В данном случае в командной строке отобразится только время последней загрузки. Чтобы вычислить значение uptime, как разницу между текущим временем и временем загрузки Windows, воспользуйтесь PowerShell командами:
$boot_time = Get-CimInstance Win32_OperatingSystem | select LastBootUpTime
(Get-Date) - $boot_time.LastBootUpTime | SELECT Days,Hours,Minutes,Seconds
Команда вернет значение аптайма компьютера в днях и часах.
В новых версиях PowerShell Core 6.x и 7.x для получения времени работы системы можно использовать новый командлет Get-Uptime. Это командлет сразу выведет значение uptime в днях, часах, минутах (в формате TimeSpan). Или можно вывести время с последней загрузки компьютера:
Get-Uptime -Since
Можно получить значение аптайм с удаленного хоста:
$remotePC='pcbuh01'
(Get-Date) - (Get-CimInstance Win32_OperatingSystem -ComputerName $remotePC).LastBootupTime
Эту команду можно использовать для удаленного опроса uptime компьютеров в домене AD. Для получения списка компьютеров обычно используется командлет Get-ADComputer.
Обратите внимание, что на десктопных версиях Windows 10 и 11 по умолчанию включена функция гибридной загруки (Быстрый запуск, Fast Boot). В этом режиме, когда пользователь выключает компьютер, Windows фактически не выключается, а выгружает ядро и драйверы в файл гибернации. В этом случае (как и после пробуждения после режима сна и обычной гибернации) аптайм компьютера не сбрасывается при включении.

On Windows 10, understanding how long a device has been up and running can be useful information in many scenarios. For example, when troubleshooting problems, you may want to know if a reboot was recently applied or if your computer is acting up while working on an important project, and you suspect a restart is required.
Whatever the reason, Windows 10 doesn’t make it obvious to see your system uptime, but it’s not impossible to find either, as you can deduce this information using Task Manager, Control Panel, Command Prompt, and PowerShell.
This guide will walk you through four simple ways to check your device uptime without scripts or restarting.
How to check PC uptime using Task Manager
The easiest way to check your device uptime is using Task Manager with these steps:
- Open Start.
- Search for Task Manager and click the top result to open the experience.
- Quick tip: You can also open Task Manager using the «Ctrl + Shift + Esc» keyboard shortcut or by right-clicking the taskbar and selecting Task Manager from the menu.
- Click the More details button (if you’re using the compact view).
- Click the Performance tab.
- Select the CPU section.
Once you complete the steps, you’ll see your device uptime on the right, at the bottom of the page.
How to check PC uptime using Control Panel
Another easy way to determine your system uptime is to check your network adapter status with these steps:
- Open Start.
- Search for Control Panel and click the top result to open the experience.
- Click on Network and Internet.
- Click on Network and Sharing Center.
- Click the «Change adapter settings» option in the left pane.
- Double-click the network adapter connected to the internet.
After completing the steps, you can deduce your computer uptime using the «Duration» information, which indicates the uptime from the network connection that resets every time the device starts. However, this method work as long as you didn’t reset your network connection since the last time you booted the device.

How to check PC uptime using Command Prompt
If you want to use Command Prompt to check your device uptime, you have at least two ways to do it.
WMIC method
To check the device uptime with Command Prompt on Windows 10, use these steps:
- Open Start.
- Search for Command Prompt, right-click the top result and click the Run as administrator option.
- Type the following command to query the device’s last boot time and press Enter: wmic path Win32_OperatingSystem get LastBootUpTime
Once you complete the steps, you’ll notice an output may look intimidating, but it’s not difficult to decode so you can understand your device’s uptime.
For example, the LastBootUpTime 20220919073744.500000-240 can be broken down using the info below.
- Year: 2022.
- Month: 09.
- Day: 19.
- Hour: 07.
- Minutes: 37.
- Seconds: 44.
- Milliseconds: 500000.
- GMT: -300 (5 hours ahead of GMT).
This means that the computer has been up and running since September 19, 2022, at 07:37 AM. If you want to be more specific, subtract the last boot time from the current time to deduce the number of days, hours, and minutes the device has been in operation.
System Information method
You can also see your system uptime in a more user-friendly format using the System Information tool with these steps:
- Open Start.
- Search for Command Prompt, right-click the top result and click the Run as administrator option.
- Type the following command to query the device’s last boot time and press Enter: systeminfo | find «System Boot Time»
The System Information tool can quickly show the last time your system rebooted in an easy-to-read format. Also, like the wmic command, you can subtract the last boot time from the current time to determine the number of days, hours, and minutes the device has been running.
How to check PC uptime using PowerShell
It’s also possible to check your device uptime using PowerShell with these steps:
- Open Start.
- Search for Command Prompt, right-click the top result and click the Run as administrator option.
- Type the following command to query the device uptime and press Enter: (get-date) — (gcim Win32_OperatingSystem).LastBootUpTime
After completing the steps, you’ll get the uptime information in a list format with the days, hours, and minutes.
This guide outlines several ways to check your device uptime, but it’s important to note that there are many other methods to find the same information using Command Prompt and PowerShell scripts. However, these are the most straightforward methods.
In addition, while these instructions are focused on Windows 10, these methods have been around for a long time, which means they’ll also work on Windows 8.1 and 7.

Computer uptime is the amount of time the computer has been running continuously since the last reboot, without a shutdown or restart. PC uptime is useful in troubleshooting different computer issues. This is used especially by network admins for troubleshooting purposes.
Computer uptime is synonymous with Windows uptime, as both are almost the same. You can check Windows uptime by using the network adapter stats from the task manager, a command prompt or Powershell. We will discuss each method one by one.

Quick Summary
Check uptime from Task Manager
The quickest way to check uptime in Windows 10 and Windows 11 is to use the Task Manager. The biggest advantage of using the Task Manager is that it shows the uptime in real-time to the seconds precision.
-
Open Task Manager by right-clicking on the taskbar and selecting Task Manager (Ctrl + Shift + Esc).
-
Go to the Performance tab and go to the CPU section where you will see the uptime in days: hours: minutes: seconds in real-time.
Showing Up time in Task Manager
Clarification: There is one clarification here. Windows calculates the total uptime of the computer. This is like CPU uptime, the time CPU has been active. If you put the computer to sleep or hibernate mode, those times will not reset the uptime timer. When the computer returns to an active state, Windows will start calculating the uptime from the same position where it left off.
For example, if my computer was active for 2 hours and then I hibernated it for 24 hours. I started the computer again and used it for two more hours. Windows will calculate the total uptime as 4 hours.
Check uptime using the network adapter
Another way to quickly check the current system uptime is to check the active network adapter status. This only works if your network is always connected.
- Right-click on the network icon in the system tray and select “Open Network & Internet settings“.
- From the Status section, click on “Network and Sharing Center”. Or simply go to Run –> control /name microsoft.networkandsharingcenter
- Click on the active network adapter link
- The opening window will show the uptime.
Basically, this is the network uptime. This will reset if the computer goes to sleep or hibernation.
Check PC Uptime On Windows Using Command Line
You can also check the uptime using the command-line.
Systeminfo
Systeminfo is a command that lists general information about the Windows system. It lists the last boot time of Windows. We will need to manually calculate how much time has passed so far.
Open command prompt by going to Run –> cmd and run the following command:
systeminfo | find “System Boot Time”
WMIC
There is another WMIC command, which will let you know about the boot time of the computer as a string. This can be helpful for developers and DevOps.
Open the command prompt and run the following command:
wmic path Win32_OperatingSystem get LastBootUpTime
If you see the above screenshot of my computer, you will know that the boot time of my computer was:
Year: 2019 + Month: 09 + Day: 13 + Hour: 15 + Minutes: 24 + Seconds: 00 + Milliseconds: 500000.
The last +300 is the time zone. That means I’m in GMT + 3 timezone.
Net Statistics utility
Net Statistics command can be used to check the last boot time:
Open the command prompt and run the following command:
net statistics workstationThe line starting with Statistics since is your boot time.
The same command can be used to check Windows Server uptime but the command will become net statistics server.
Check system uptime using PowerShell
PowerShell gives a clearer answer using the same string as the command prompt. It will calculate the uptime instead of the last boot time. It also shows the total no. of days, hours, minutes and seconds separately.
Open PowerShell and run the following command:
(get-date) - (gcim Win32_OperatingSystem).LastBootUpTime
If you are using PowerShell 6, then you can simply use the following command to get the Windows uptime and the last startup time:
Get-Uptime -SinceDifference between uptime and availability?
Most people confuse uptime with availability. Before moving forward, we should know the difference between uptime and availability. They are not the same. According to Wikipedia:
Uptime is a measure of system reliability, expressed as the percentage of time a machine, typically a computer has been working and available.
Availability is the probability that a system will work as required when required during the period of a mission.
A computer may be up and running, but the resources required for a specific operation may not be available depending upon the system load. For example, a computer may be running, but its network card may not work properly or its bandwidth is being overused. In this case, the system has uptime, but it is not available for the specific task.
Final thoughts
Default allows Windows to start quickly on Windows 10. If enabled, Windows will not reset the LastBootUpTime value. You will not get the exact Windows uptime. To disable fast startup quickly, run the following command:
powercfg -h offIf you want to check the current Windows uptime, you will need to use the network adapter method to check the network time. But it only works if you are always connected to the Internet.
These are some ways to quickly get the last boot time or check the total uptime of the computer. Every command has its own advantages. You can use the method which suits you best. The only thing I haven’t found is the answer to how old is my computer? The systeminfo command only gives information about the Windows installation date and time. Maybe BIOS can show me something about that. Most of the methods mentioned above work with all versions of Windows, including Windows 10, Windows 8, Windows 7, Windows Vista. You can also check Windows Server uptime using the same commands.
Please tell me about how you check the uptime of your computer and for what purpose do you use this information?
