#How to Run the Script
#powershell.exe -NoProfile -ExecutionPolicy Bypass -File C:\temp\disconnect-users.ps1


#Explanation of the Command:
#powershell.exe → Runs the PowerShell interpreter.
#-NoProfile → Runs PowerShell without loading user profiles for a faster startup.
#-ExecutionPolicy Bypass → Bypasses PowerShell's execution policy to allow the script to run.
#-File C:\temp\disconnect-users.ps1 → Specifies the script file to execute.
