#    Name: Inventory-Applications.ps1
# Purpose: Queries a local or remote computer for information about software
#          applications installed, then exports the data to a CSV file which
#          can be opened in a spreadsheet.  The output from scanning multiple
#          computers can all be appended to one file (each line in the CSV file
#          will have the name of the computer).  By default, the script creates
#          a file in the present directory named ApplicationsInventory.csv.
#          However, beware, there are issues when using the Win32_Product class!
