When your operating system is in trial mode, a default product key is installed. To modify it, open the `Run
` dialogue box by pressing the Windows key on your keyboard + `R
`.

In this box, enter the following command:

```bash
cscript.exe c:\windows\system32\slmgr.vbs -upk

Core versions use the same product keys as non-core versions.

` dialogue box:
