No matter what I try, Excel 2013 continues to run in the background on Windows 10 no matter what commands I throw at the end of my PowerShell script. I've tried adding all suggestions I've found to the end of my script and the only Excel object I open continues to remain open. Here is what I have at the end of my script. Any other suggestions?
## Quit Excel and Terminate Excel Application process:
$xlsxwb.quit
$xlsxobj.Quit
[System.Runtime.Interopservices.Marshal]::ReleaseComObject($xlsxobj)
[System.Runtime.Interopservices.Marshal]::ReleaseComObject($xlsxwb)
[System.Runtime.Interopservices.Marshal]::ReleaseComObject($xlsxSh1)
Start-Sleep 1
'Excel processes: {0}' -f @(Get-Process excel -ea 0).Count
