- The wireless button driver is required to use the wireless keys.I would keep this
- HP support assistance is good to keep but not necessary
- Simple Pass is the software package for the fingerprint reader on supported PC's.If you dont need to use it or dont have it this can be removed
- Cool sense automatically adjusts your PC cooling to prevent overheating(probably not necessary)but no harm in keeping it
- System Event Utility enables special function keys on the system to be programmed(probably not necessary)no harm in keeping
- HP Documentation provides warranty info and user guide.It has been known to be bundled with 3rd Party software therefore I would say this can be removed as this information is readily available if need be.
Some of these really do no harm in keeping them.If any are enabled in startup they can easily be disabled if you don't find you need them.Some are required for certain built in functions especially drivers.IMO some are worthwhile to keep and you really don't gain anything by uninstalling them.I would be more concerned with ridding a new PC of all the 3rd party crapware programs installed on a new PC.These would include games,video programs,Antivirus trials(unless you are going to use it),etc. and everything else that you have no use for.
If you are unsure about something this is a kind of handy tool

As has been mentioned above IObit Uninstaller or Revo Uninstaller will work well in getting rid of all traces of these programs.
