Office 2016 - Recover Product Key for Home & Business Edition on Win 8.1 &32bit Office

Hello
looking for some sensible way to recover office 2016 Home and Business product key
I have already tested many different types of programs and none showed the key even did not detect that office 2016 is installed and activated

I've only come to the last 5 characters through cscript

system description:
Windows 8.1 64bit
Office 2016 32bit

if someone knew a solution to this problem I would ask for info
greetings

Welcome. From what I read only the last characters are stored in an explicit form, the entire key is encrypted in the registry. Therefore, key extraction programs cannot see Office 2016 (and the older version of 2013 also). Nowhere did I find information on how to get the key from this character.

Have you contacted Microsoft support to help solve your problem? Probably the product is assigned to a Microsoft account, the manufacturer should best help in this topic.

In this case, I don't know if the MS helpline can help. Once I had to determine which license was used on one of the computers (I had 2 the same packages and 2 different keys). I had to provide both keys and product identifier and only after that I got the answer on the hotline that this particular key is assigned to a specific product identifier. The other key remained unassigned and I could use it. You couldn't do the opposite.

and here is the problem
microsoft won't help

and the last 5 characters do not arrange me because I have office 2016 installed on 10 computers and 2 boxes with keys and accounts
so i don't even get my keys back

If you have 10 keys on 10 computers, then the MS telephone will arrange you. You provide all computer codes and keys and the method of elimination (provide codes from the other 9 computers) will give you the one key you are looking for.
