Thanks for this script, in my own version I've added a line to display the deployed WebApplications : Get-SPSolution | select SolutionId, Name, DisplayName, Deployed, DeploymentState, SolutionFile, ContainsGlobalAssembly, ContainsWebApplicationResource, JobExists, Version, @{Name='DeployedWebApplications';Expression={[string]::join(";", ($_.DeployedWebApplications))}} | Export-CSV $bkdir\SPSolution.csv
