PowerShell Uninstall Automation

I have authored the PowerShell Uninstall script.  It gives the ability for IT Operations / ConfigMgr Admins to uninstall multiple versions of a particular software with one process.

Does your organization struggle when trying to cleanup software when standardizing on a application version? I.E. Oracle Java, Adobe Flash, RightFax, IBM products, etc…  Not all the versions you have are in ConfigMgr / SCCM or not in the application model?  If the answer is yes, the PowerShell Uninstall script is for you.

The PowerShell Uninstall script takes inputs from a CSV file.  Using the delimiter of “^”, don’t worry I have included a Excel file to build your CSV.

Since by nature when uninstalling legacy software there maybe pre-or post- process you must run. The PowerShell Uninstall script has functions to call a PowerShell script before or after the uninstall logic.

The PowerShell Uninstall script also includes a Boolean to  create the script as an ConfigMgr / SCCM Application.  In which you can attach to other programs for requirements.

To detect the PowerShell Uninstall script, have ConfigMgr / SCCM check existence of “%SystemDrive%\Program Files\Pomeroy\AppName”.  It will be an empty directory.  For the uninstall just use the command “rmdir /Q /S %SystemDrive%\Program Files\Pomeroy\AppName”
