Activate Windows from command line



How to activate Windows from command line?

If you have decided to convert an evaluation Windows server (Windows 2016 or other server version), or Windows 10 to a license Operating system then you need to replace the product key.
You will need to change the product key and activate the system, in order to use the product outside of its evaluation period.

Assuming you have done the steps of converting the evaluation software and all the evaluation packages has been removed. Of course, if you have plenty of time in your hands and you just want to redo everything then you can just install or setup a new environment.

To activate a new product key from command line, first the product key must be installed and replaced the existing one. Second, activate the product key.

Here’s how to do it via command line:

a. slmgr /ipk windows-product-key-with-slashes

/ipk = installed product key
windows-product-key-with-slashes – replace this with the actual windows product key

If everything goes well there will be a pop-up message notifying that the operation was successful.

b. slmgr /ato

Just type the above command to activate the newly installed product key, if everything goes well then a pop-up message will appear to notify that activation was successful and also the watermark for the evaluation will be removed.

/ato – most probably this means activate online
Slmgr /ato – should be done while the machine is online.


Till next time. Cheers~!

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 need to install the resource kit tool if the operating system is Windows 7 or newer version.

Copy files with selected file extension using PowerShell and Robocopy:

$extension = ('.pdf', '.jpg', '.txt')
