Opening certmgr.msc to display the Machine level certificates
Solution 1:
certlm.msc will open the local machine store.
Solution 2:
Adding the snap-in to the a "blank" MMC instance is the only way I'm aware of to open the machine's certificate store in the management console. You can always save that console, if you'd like, so that you don't have to manually add the snap-in in the future, but the default certmgr.msc saved console has the Certificates snap-in targeted at the user.
