Windows Server Core - check for installed roles and features

How to find all roles and features installed at Windows Server 2008 Core without remote MMC console...?? How to easily do this without looking at the entire oclist.exe tree...??

There are two simple methods:

• oclist.exe |find "Installed" |find /v "Not Installed"

And if you have the W2K8R2 version you can use dism.exe command:

• dism.exe /online /get-features /format:table |find "Enabled"
