title: How can I stop Excel processes from running in the background after a PowerShell script?
body: <p>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?</p>
  
  <pre><code>## 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
  </code></pre>
