It’s well known that you can jump to MMC snap-ins by running them directly however one anomaly is Certificate Manager, this actually has two different commands depending on which store you need:
Certmgr – Opens the certificate store for current user
Certlm – Opens the certificate store for the local machine
What if you want to view the details directly in a PowerShell prompt?
Just use the Get-ChildItem and point at the appropriate store:
gci Cert:\CurrentUser\My
gci Cert:\LocalMachine\My\
