Overview
HP Power Assistant is a program developed by Hewlett-Packard. It is bundled and preinstalled with various Hewlett-Packard computers. The most used version is 2.5.0.16, with over 98% of all installations currently using this version. Upon installation and setup, it defines an auto-start registry entry which makes this program run on each Windows boot for all user logins. It adds a background controller service that is set to automatically run. Delaying the start of this service is possible through the service manager. A scheduled task is added to Windows Task Scheduler in order to launch the program at various scheduled times (the schedule varies depending on the version). The main program executable is HPPA_Main.exe. The software installer includes 19 files and is usually about 15.6 MB (16,355,239 bytes). In comparison to the total number of users, most PCs are running the OS Windows 7 (SP1) as well as Windows 10. While about 44% of users of HP Power Assistant come from the United States, it is also popular in France and Germany.
This program is pre-installed on the PC
Such software is installed by the manufacture when delivering the PC to the end user. Some pre-installed programs are considered bloatware as they are simply limited function trials, while others are required for proper PC operation.
Note: This program has often been considered as bloatware by some users as it is bundled on various manufacturer's new PCs. (Because this might be considered bloatware does not mean the software is bad or harmful, if you use it regularly its worthwhile to have. However, bloatware typically means the program is optional and was simply pre-installed but is not required and can be removed.) Some quick tips to be aware of:
- It is usually licensed for use only on the HP PC on which it was pre-installed.
- It sometimes difficult for users to remove via the 'Uninstall a Program' feature in Windows.
