How to delete all SharePoint webs in a Site Collection, except the root web

Pretty useful and simple to delete all webs in a site collection except the root web. This worked for me, because there isn’t nesting. Even with nesting and the pipeline returning SPWebs in suboptimal sequence, running this a few times will wipe at a minimum the leaf nodes whittling you down to your clean root web.

get-spsite ht tp://SharePoint SiteURL | get-spweb -Limit all  | Where-Object {$_.isrootweb -ne $true} | % {$_.delete()}
