PowerShell check Windows boot time and uptime


Checking boot time is essential in determining the server or workstation uptime.

If ever there is a server or computer that is not supposed to be rebooted or shutdown but then to check whether the server or computer hasn’t done a power cycle is to check its uptime.

Checking the uptime will determine how long the server has been online.

PowerShell is just an awesome tool to do this kind of task.


Here’s the script:

#run a command line using PowerShell
$boot_time = & systeminfo | find "System Boot Time"
Write-Output $boot_time

#display a pop-up message box using PowerShell
[System.Windows.MessageBox]::Show('Hello, the ' + $boot_time)

#split string using regex and match spaces
$splitx = $boot_time -split '\s+' -match '\S'

#get the 4th array on the array element
$xtime = Get-Date $splitx[4]

#get the current date and time of the system
$Date = Get-Date

Write-Output $date

#subtract the current date and time with the boot time
$get_duration = $Date - $xtime
$xmin_total = $get_duration.TotalMinutes

#convert the minutes to hours and minutes
$time_var = new-timespan -minutes $xmin_total
$uptime_hours = $time_var.Hours 
$uptime_minutes= $time_var.Minutes

$uptime_total = ($uptime_hours,  " hours and "  ,$uptime_minutes , " minutes")

Write-Output $uptime_total

[System.Windows.MessageBox]::Show('Hello, server uptime is: ' + $uptime_total)

Cheers!

Till next time.

WMIC get computer name

WMIC get computer model, manufacturer, computer name and  username. WMIC is a command-line tool and that can generate information about computer model, its manufacturer, its username and other informations depending on the parameters provided. Why would you need a command line tool if there’s a GUI to check? If you have 20 or 100 computers, or even more. It’s quite a big task just checking the GUI to check the computer model and username. If you have remote computers, you need to delegate someone in the remote office or location to check. Or you can just write a batch file or script to automate the task. Here’s the code below on how get computer model, manufacturer and the username.

Print error 016-799 - Fuji Film Xerox

016-799 Fuji Xerox or Fuji Film print error code. That shows a description error as “Print instruction Fail detected in decomposer.” The error code and error description are alien languages for users and even system administrators who are not familiar with Fuji Xerox error code. The error code is quite simple and easy to fix, if the job print goes to the printer but print out doesn’t come out. So, basically the print job was received by the printer, but the printer just doesn’t know what type of paper or what size to use or which tray to utilize for the print out. In some instances, this is just a paper mismatch but the error description; if using Windows 10 to print does not exactly points to what is the issue. First thing to check, is the paper size selected by the user to print. Example, if the printer configuration is A3 and A4 sizes only. But then the person printing the file accidentally chooses “A4 Cover” then this error 016-799 will occur. ...
