Last reboot refers to the point in time when a computer system was last restarted. Restarting a system, also known as rebooting, is a process that terminates all running programs and services, closes all open files, and then restarts the operating system. Rebooting can be necessary for various reasons, such as installing software updates, resolving system errors, or troubleshooting hardware issues. Keeping track of the last reboot time can be useful for system administrators, IT professionals, and users who want to monitor system uptime, identify potential issues, or troubleshoot problems.
In Microsoft Windows operating systems, there are several ways to check the last reboot time. One method is through the Event Viewer, a built-in tool that records system events and logs. To access the Event Viewer, open the Windows Start menu and type “Event Viewer.” In the Event Viewer window, expand the “Windows Logs” section and select the “System” log. Scroll through the log entries until you find an event with the source “Microsoft-Windows-Kernel-Power” and the event ID 41. The “Time Created” field of this event entry indicates the last reboot time. Another method to check the last reboot time is through the Command Prompt or PowerShell. Open the Command Prompt or PowerShell as an administrator and type the following command:
systeminfo | findstr /C:”System Boot Time”
The output of this command will include a line that starts with “System Boot Time,” followed by the last reboot time.
If you need to check the last reboot time of a remote Windows system, you can use the WinRM (Windows Remote Management) command-line tool. The following command will retrieve the last reboot time of the remote system:
winrm WMI enumerate win32_operatingsystem -Filter “Name=’win32_operatingsystem'” | findstr /C:”LastBootUpTime”
The output of this command will include a line that starts with “LastBootUpTime,” followed by the last reboot time in CIM_DATETIME format.
1. Event Viewer
The Event Viewer is a crucial tool for examining detailed system logs, including the last reboot time. It serves as a centralized repository for events and errors recorded by Windows, providing valuable insights into system behavior and potential issues.

2. Command Prompt
The Command Prompt is a powerful tool for managing and troubleshooting Windows systems. Among its many capabilities, the “systeminfo” command provides a wealth of information about the system, including the last reboot time.
To use the “systeminfo” command to check the last reboot time, simply open the Command Prompt and type the following command:
systeminfo | findstr /C:”System Boot Time”
The output of the command will include a line that looks something like this:
System Boot Time: 2023-03-08 14:32:15
This line indicates that the system was last rebooted on March 8, 2023 at 2:32:15 PM.
Knowing the last reboot time can be helpful for a variety of reasons. For example, it can help you to troubleshoot system problems, track system uptime, and identify potential security risks.
For example, if you are experiencing system problems, you can check the last reboot time to see if the problems started after a recent reboot. If so, it is possible that the problems are caused by a software update or hardware change that was made during the reboot.
Similarly, if you are concerned about security risks, you can check the last reboot time to see if it corresponds to a time when you know that your system was compromised. If so, you can take steps to mitigate the risks, such as changing your passwords and installing security updates.
In conclusion, the “systeminfo” command is a valuable tool for checking the last reboot time in Windows. This information can be helpful for troubleshooting system problems, tracking system uptime, and identifying potential security risks.
3. PowerShell
PowerShell is a powerful scripting and command-line interface for Windows systems. It provides a wide range of cmdlets, or commands, for managing and troubleshooting the system. One such cmdlet is “Get-WinEvent,” which allows users to retrieve events from the Windows Event Log.
The “Get-WinEvent” cmdlet can be used to obtain the last reboot time of a Windows system. This information can be helpful for troubleshooting system problems, tracking system uptime, and identifying potential security risks.
To use the “Get-WinEvent” cmdlet to check the last reboot time, open PowerShell and type the following command:
powershellGet-WinEvent -FilterHashTable @{LogName=”System”; ID=41} | Select-Object -ExpandProperty TimeCreated
The output of the command will include a line that looks something like this:
TimeCreated : 2023-03-08 14:32:15
This line indicates that the system was last rebooted on March 8, 2023 at 2:32:15 PM.
The “Get-WinEvent” cmdlet is a versatile tool that can be used to retrieve a wide range of information from the Windows Event Log. By using the appropriate filters, you can easily obtain the last reboot time of a system.
In conclusion, PowerShell offers a powerful and flexible way to check the last reboot time in Windows. The “Get-WinEvent” cmdlet provides a simple and effective way to retrieve this information, which can be valuable for troubleshooting, system monitoring, and security audits.
4. Remote Systems
In today’s interconnected world, system administrators are often tasked with managing and maintaining multiple Windows systems, both locally and remotely. Monitoring the uptime and stability of these remote systems is crucial for ensuring optimal performance and minimizing downtime.
The WinRM (Windows Remote Management) tool plays a vital role in enabling administrators to check the last reboot time of remote Windows systems. WinRM is a powerful command-line utility that allows users to perform various management tasks on remote systems, including retrieving system information and managing services.
To check the last reboot time of a remote Windows system using WinRM, administrators can use the following command:
winrm WMI enumerate win32_operatingsystem -Filter “Name=’win32_operatingsystem'” | findstr /C:”LastBootUpTime”
This command will return the last reboot time of the remote system in CIM_DATETIME format. Administrators can then convert this timestamp to a more readable format using online tools or scripts.
The ability to check the last reboot time of remote Windows systems is essential for several reasons. Firstly, it allows administrators to monitor the uptime of remote systems and identify any potential issues or stability concerns. Secondly, it helps in troubleshooting problems by providing a reference point for when a system was last rebooted.
For example, if a remote system is experiencing performance issues or application crashes, checking the last reboot time can help determine if the problems started after a recent reboot. This information can then be used to narrow down the possible causes of the issues and implement appropriate solutions.
In conclusion, the WinRM tool is an invaluable asset for system administrators who need to check the last reboot time of remote Windows systems. By leveraging WinRM’s capabilities, administrators can proactively monitor remote systems, troubleshoot problems, and ensure optimal system performance.
