This is not a question we can answer for you. You would need to look at that certificate and determine what it is being used for. If its not being used or you don't know why its there, then it may be unneeded and nothing needs to be done.

If this is server 2012 R2 or Windows 8+, you can run certlm.msc and look in Certificates\Personal to see the certificate and determine its purpose.

Thanks for your reply mark greatly appreciated I have many other things I need to fix 15 errors in total and 7 warnings as well so peace of mind puts my mind to ease a little will that command also work on windows 7 or what is different about 2012 R2 compared to windows 7 I understand they are different operating systems entirely since server 2012 r2 is virtual? don't get me wrong but if that command works on windows 8 and up as well as server 2012 r2 then why would it not work on windows seven? which was made after server 2012? Unless windows seven was made before? That being said the errors I would like to try to fix on my own before asking for help as I have a good knowledge now about what I am doing and if I don't know I put in the hours to find out before messing around as I have learnt from past experience do not wing it if you don't know don't touch! my next question though are audit success in the management console a good thing or bad a bit of both or nothing to worry about? I'm not to concerned but I know nothing about that particular area and I would like to know more under audit failure I only have 2 in the past 7 days? so is that something to be concerned about or no what is an audit and what is the difference between audit success and failure and do they need attention or is it really nothing at all?

under information I have 184 in the past hour 724 in the past 24 hours and 6,046 in the past seven days should I pay any attention to anything under hear at all or is it safe to just let it be? I'm trying to fix my computer in tip top shape I had to fix a lot as it had a lot wrong with it its defiantly running better now but any advice I can receive is great advice. :)

Ps I know the difference between success and failure what I don't know is what the hell audits are?
