As you can see, in addition to the basic software and hardware inventory information the program output also includes information about installed hotfixes, installed applications and disk volume information. It appears in the output because we specified additional command-line switches. If you don't like the output format and prefer to have data reported in CSV format, you can specify the CSV print format option, as it's demonstrated below.

psinfo -h -s -d -c
