We started deploying 7-Zip v18.01 but quickly had to stop the deployment due to Windows Explorer crashing. A user without a toolbar is not a productive user. We tweaked our deployment and added this parameter to the install string:
Execute-MSI -Action Install -Path “7z1801-x64.msi” -Parameters “/QN MSIRMSHUTDOWN=2”
Once we added that we were able to deploy with no issues.
