It would be great to have the UninstallString (and QuietUninstallString) from the users ARP data in the registry. The EI Users Programs (EI_UserARP) does not try to capture this data. It is available in the registry: Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Uninstall\[ProductName] under UninstallString as well as QuietUninstallString.
Thanks for the great idea and for taking the time to submit and vote on it. Having user context uninstall information readily available alongside inventory data would definitely be valuable for cleanup and remediation workflows.
We've added this idea to our review process and will consider it as we continue enhancing application and software inventory capabilities. Thanks again for helping shape the future of the product.
This would be very valuable data, especially for teams performing software audits. They can silently uninstall software under the user profile if this data was more readily available.
