Windows Installer iterates through each of the installed applications, checks for changes, and takes action accordingly. This would not a terrible thing to do in your dev or test environment. So what is the best solution to determine installed applications? For me, it is reading from the registry as it involves less risk of invoking changes to our production environment.
The script points to a CSV file that I keep up to date with a list of servers from our domain. Define the variable to hold the location of Currently Installed Programs. Retrieve an array of string that contain all the subkey names.
Open each Subkey and use GetValue Method to return the required values for each. When I am done, I simply output the array and pass it through a Where-Object to display only those entries with something in the DisplayName.
This is handy because I can then refer back to just the array if I need to supply different output. Say I want to only report on a specific server.
