The download is freely available from Dell’s PowerGUI community.

The community itself also got moved from http://powergui.org to http://en.community.dell.com/techcenter/powergui.

UPDATE: Looks like Dell took the community site down but direct download link http://community-downloads.quest.com/powergui/Release/3.8/PowerGUI.3.8.0.129.msi still works.

Quest / QAD cmdlets

This one is a little more tricky to find: https://software.dell.com/register/71110

If this link for some reason changes, all Dell’s freeware and trial links can be found in this catalog: http://software.dell.com/trials/

UPDATE: Looks like this got hidden even further. Not sure where it can be found now. This site seems to have copied and made them available for download though: http://www.powershelladmin.com/wiki/Quest_ActiveRoles_Management_Shell_Download

Alternate link that includes 1.5 and 1.6 can be found here.

Happy PowerShelling!
