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

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

Notepad++ convert multiple lines to a single line and vice versa

Notepad++ is an awesome text editing tool, it can accept regex to process the text data. If the data is in a “.csv” format or comma separated values which is basically just a text file that can either be opened using a text editor, excel or even word. Notepad++ can process the contents of the file using regex. Example if the data has multiple rows or lines, and what is needed is to convert the whole lines of data into a single line. Notepad++ can easily do it using regex. However, if the data is on a single line and it needs to be converted into multiple lines or rows then regex can also be used for this case. Here’s an example on how to convert multiple rows or lines into a single line. Example data: Multiple rows, just a sample data. Press Ctrl+H, and  on "Find what" type: [\r\n]+ and on "Replace with" type with: , (white space) --white space is needed if need to have a space in between the data.

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.
