How to List All Installed Applications From the Command Line

One simple command to list all installed application :
wmic product

We can also save them into the .csv file with this comamnd :
wmic product get /format:csv > Software_%Computername%.csv

If this command failed with this error : Invalid XSL format (or) file name.
You should change the Regional and Language to English (US) and re-run the command it should be generated file like : Software_COMPUTERNAME.csv
