Lock computer using PowerShell


To lock a computer using PowerShell, use the old school command prompt and invoke the command in PowerShell.

This can be handy to lock a computer and use Task Scheduler, to run the script at an specified time.

Link below shows on how to set Task Scheduler:

Below is the PowerShell code to lock a computer:


$xCmdString = {rundll32.exe user32.dll,LockWorkStation}

Invoke-Command $xCmdString


Try to run the code on PowerShell ISE to see how it works. It will just lock the computer, and you will need to press Ctrl+Alt+Delete and enter your password to login again.

Copy a single file using robocopy

Copy a single file using robocopy from a local folder to a shared folder on the network.
A simple rule of thumb before any disaster strike, don't interchange the source and the destination.

If source and destination is mistakenly reverse, files might get overwritten. To avoid any loss of data do a test with a dummy file to ensure things work perfectly.
Robocopy [source][destination]   [file to be copied]
robocopy c:\local_c_folder  \\PC_network\shared_folder   file_to_be_copied_xx.txt
The command will be completed successfully provided the network access right has no issues.

Robocopy works quite good on large files. A simple copy or xcopy command will also work but the speed might vary.

Robocopy is free it can be accessed from command line. No ne…

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.
