"lab-AAA-pri" Windows certificate?

I found this certificate in the search results when running Sigcheck:

lab-AAA-pri
Cert Status: Valid
Valid Usage: All
Cert Issuer: lab-AAA-pri
Serial Number: 00
Thumbprint: 2AF2F6D1C749C91E781E838EEB634F94645DDEB2
Algorithm: md5RSA
Valid from: 5:09 PM 5/25/2007
Valid to: 5:09 PM 5/22/2017

Anyone know what it is or what programs it’s associated with?

Ask the issuer.

If I knew who they are, I wouldn’t need to ask.

Cert Issuer: lab-AAA-pri

I could see that in the report I pasted above.
My question is who’s that, and what programs can be associated with it.
As they’re apparently small and there’s no discussion about them that Google picks up, there’s no way to research them.

Certificates are (to my knowledge) not for a application, they are for data transport protocols. (e.g. hpptS)

Google is your friend.
Lookup the contact details of the issuer and ask them for what/who they have issued the certificate.

Perhaps you’ll have better results.

You’ve downloaded a tool from Sysinternals why not ask on their forum:http://forum.sysinternals.com/
