PowerShell: End disconnected sessions

The PowerShell script below logs off a disconnected session if the session has been idle for XX minutes, and it also excludes specific users. Additionally, the script writes a log file that includes the memory usage of the session

# Define the list of users to exclude from logoff
$excludedUsers = @("user1", "user2","user3")
# Define the maximum allowed idle time (in minutes). Minimum 60 minutes
$maxIdleMinutes = 2880
