What you have to do is select first what activator do you need.
As I mention above this tool is 2 in one software, yes you can activate up to 8.1 and up to MS office 2013. Then provide the code which is getting from the toolkit. What you have to do is click phone button and get the 12 digit code and call Microsoft through Skype. Also toolkit support manually call activation system.
Auto KMS and EZ activator modules are built in to provide a perfect activation algorithm. Microsoft toolkit is a combination of all activators.
