I was recently helping a bank network support client install an update to a Jack Henry application named Yellowhammer. Normally we save the installation file to the network of that certain program just for organizational purposes.
Upon reading the instruction I just save the .exe file to the user's PC because I wanted to see what files needed to be updated. However, upon running the installation it just opened a GUI that setup a connection back to Jack Henry. We closed out the program to begin saving the program to the network. When we did this ALL THE DESKTOP ITEMS DISAPPEARED from the user's PC. [more]
After looking into what files were unzipped I came across a file name “cleanup.bat” which deleted whatever folder these files were located, and in our case it happened to be the Desktop folder.
I am just curious as to what would have happened if I saved this anywhere else. So for future reference, check for a cleanup.bat file in any Jack Henry Installation.
