Hi Charlie. I'm Greg, an installation specialist and 9 year Windows MVP, here to help you.
It depends on how much of a purist you are. Many enthusiasts won't run any factory bloatware and choose to do the best possible Clean Install following the illustrated steps in this link which include everything that works best in Windows 10: http://answers.microsoft.com/en-us/windows/wiki...
There is also an automated Fresh Start that reinstalls Windows while shedding factory bloatware that can cause issues and affect performance, saves your files, but doesn't clear the drive to get it cleanest: https://www.howtogeek.com/265054/how-to-easily-...
But some HP programs can be useful. CoolSense controls the fan speeds in case it gets hot.
Jumpstart is just an introductory app which pushes the most pernicious preinstalled bloatware McAfee or Norton (use Defender for best Windows Performance), nags you to register, etc. Same with Documentation. You can register if you want but they still owe you a year's Support and Warranty if you do or not. https://www.quora.com/What-are-the-uses-of-the-...
Support Assistant has some useful features like the Updater and link to Support and Diagnostics: https://support.hp.com/us-en/document/c03467905

HP System Event utility allows users to program further the Hotkeys which may also rely on it to function on some models. Discussion and replacement download here: https://h30434.www3.hp.com/t5/Notebook-Operatin...
Some models have an HP Wireless manager on top of Windows superior manager, but it requires disabling it before uninstalling.
I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.
