How to Check Uptime on Windows Server Using Powershell?

4. Calculate server uptime: The `LastBootUpTime` property returns the date and time when the server was last booted. You can use this information to calculate the server uptime by subtracting the last boot time from the current time. Here’s an example of how you could calculate the uptime in hours:
"`
$lastBootTime = (Get-CimInstance -ClassName Win32_OperatingSystem).LastBootUpTime
$uptime = (Get-Date) – $lastBootTime
$uptime.TotalHours
"`

By utilizing these methods, you can easily monitor the uptime of a website or online service. Remember that monitoring uptime helps ensure that your website or service remains accessible and performs optimally for the end-users.
