The Health Guide stuff can go. You are a better judge of the health of your system than HP....
The Support Library you dont need. You have us here at tech forums.
Customer Experience enhancements? Do you get like a cool new theme or something with that?
User Guide. Well if you didnt know how to use aPC how would you know how to use that?
That stuff can go. Use PC Decrapifier.
Welcome | The PC Decrapifier
Get rid of all that HP stuff. It isnt needed.
