ProduKey

ProduKey reads the product key for Windows and Office that is already installed on a computer you own. Use it when the sticker or the old key document is gone and the machine still has the installation. Microsoft flags the download because the program reads product keys out of the registry, which is the same behavior as a piracy tool. SmartScreen and Defender call that a hacktool. NirSoft publishes it as a recovery utility, and the warning is about that capability, not a broken page.

Technitium MAC Address Utility

Technitium MAC Address Changer allows you to change (spoof) the Media Access Control (MAC) Address of your Network Interface Card (NIC) instantly. It has a very simple user interface and provides ample information regarding each NIC in the machine. Every NIC has a MAC address hard coded in its circuit by the manufacturer. This hard coded MAC address is used by windows drivers to access Ethernet Network (LAN). This tool can set a new MAC address to your NIC, bypassing the original hard coded MAC address.
