HP CEEment is a telemetry module that is part of HP software.
HP itself describes CEEment as:
CEEment stands for Customer Experience Enhancement. CEEment (HPCEE.exe) is the reporting tool that HP uses to collect and study anonymous data. You can activate CEEment when you set up your computer. Or, you can activate using HP Advisor or HP Support Assistant at any time.
Some of the data reported using CEEment includes your model number, OS, region, locale, and BIOS version. If you wish to know specifically which data was collected, launch HP Support Assistant. Click Settings, scroll down to the bottom of the Health Analysis tab, and then click View information collected by HP.
This immunizer is available for users of the Plus version. It will only be shown within Anti-Beacon if HP CEEment is installed.
