Windows License Extractor is a small PowerShell/WinForms GUI tool that will help you to display/export licensing information (including the product key where possible) for your current running operating system, as well as other remote computer systems.
This utility can be useful if you lost the product key of your Windows, and you want to reinstall it on your computer.

I’m receiving access deny messages thought I’m using domain admin account. Is there anything I have to do before accessing the windows keys. I think I’ve already enable remote registry service on the workstations using a windows Group Policy.
