Use - Script that runs on Servers mentioned in Input.txt file, fetches details of Servers having Unallocated free space right after Recovery Partition.
Prerquistes - Copy entire code, save it in a file with .ps1 extension. On same location, create another file named "Input.txt" and mention all the servers against which this script will run.
Output - Two Output files, Output.csv containing details and Errorlogs.csv containing errors if any occued during execution of script.
