Powershell Project – Remove Profiles and Registry Entries for Users No Longer Logged On


This is an issue that I have found annoyingly common on Windows 2003 servers running Citrix over the years. For these servers you can use REMPROF to remove the orphaned users profiles and registry HKU entries, but I have found that this utility does not work for Windows 2008 R2.  With that I intend to plan out and create a script that will do the job via Powershell.

I am quite new to the use of Powershell and so I will list out the all of the steps that I go through to create the script.

The Pseudo Code for the Script:
Check logged on users
Check C:\Users for Folders
Check Registry SIDs in HKU

ForEach Folder not attached to a logged on user
Delete C:\Users\ folder

ForEach SID not attached to a logged on user
Delete HKU\SID Key

I will update this post again once I have the base set of code required to start this off

About Chris Ainger

I have been working in IT since 1998 in the Public Housing Sector. I have worked with Citrix since 2003 in the days of Citrix Metaframe XP 1.0 FR2. Since then I have been through the processes of upgrading to Presentation Server 4.0 with a farm of around 150 servers. Since then I have helped create a farm of around 200 servers using XenApp 6.0 on VMware 4.1. This was a great experience which has only increased during the upgrades of the environment for out 2000+ users. All of our clients are the WYSE 10 series using ThinOS which I have helped configure for individual users from a central location making administration very simple. I gained my CCA qualification in XenApp 6.0 in January 2012. I am a big fan of SolarWinds also, which is a great monitoring tool. It is very versatile with a small footprint of resource usage on the targeted devices. I am currently designing the interfaces for the IT department for daily use and also a Service view for the Support Desk Team. I am also a keen fisherman, having restarted again after 20 years. I set myself yearly targets to try to complete which makes this more interesting and belong to several forums of other like-minded folks. I, on occasion, fly fish for trout as a treat once in a while or when the fridge gets empty and also sea fly fish for bass and mullet. My main area is sea fishing from either beach, harbour wall or pier. There are so many species of fish to catch around the UK that you can mix up the locations to try something different.
