PowerShell Restart Computer after x minutes




Sending notification before shutting down a computer is a good practice and show kindness to users.

It will give time for the user to save whatever data that needs saving.

But of course, you can always shutdown even without notice. This could be unfair to the users.

So exercise power with caution and responsibility, Karma is always around. It never fades away.

The code snippet from Technet Scripting guy on the link below shows how to use PowerShell to display a pop-up Window.

It's better to use a pop-window than a balloon notification which user might not notice.

Using the cool Shell of PowerShell, code below will display notification before restarting the computer.

It uses the sleep command, which can also be used on batch file.

Replace the "Restart-Computer" with write-host or with a message box for testing.

Make use of PowerShell ISE, which is quite good for testing purposes.

Here's the code:

========================================

$wshell = New-Object -ComObject Wscript.Shell

$xwshell = New-Object -ComObject Wscript.Shell





#Display pop-up box and if the user does not press "ok" button

#Box will automatically close after 5 seconds

$wshell.Popup("This computer is scheduled for shutdown",5,"Save your data..",0x0)



#Display pop-up box and if the user does not press "ok" button

#Box will automatically close after 3 seconds

$xwshell.Popup("30 seconds to shutdown",3,"Please save, you got 30 seconds..",0x0)



#wait for 30 seconds before shutting down

$xCmdString = {sleep 30}

Invoke-Command $xCmdString



Restart-Computer -ComputerName Server01

=============================================

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. Open an elevated command prompt and type:     wmic computersystem get "Model","Manufacturer", "Name", "UserName" Just copy and paste the code above, the word “computersystem” does not need to be change to a computer name.

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. ...
