First project and a very important one.
Make your initial system recovery disks. Locate the HP Recovery Manager either in the Apps Section or the HP Support Assistant. On a new PC you can only make this media once and it will allow you to return the PC to Out-of-the-box condition.
Next I would make sure the Windows System Protection (Restore Points) is enabled. You can find this in Action Center (Control Panel) or white flag on bottom of screen. Recovery/Configure System Restore.
Post a screen shot of Programs & Features screen and you will get recommendations on what to remove. HP does include a lot of junk but some of it can be useful but most of it is BS. Uninstall Apps that you don't want or need.
Thanks. I made a mistake and didn't make my initial system recovery disks out of the box. Is it too late to do it now that I have installed stuff on it or can it be made from the recovery drive?
As far as what's been installed, I was looking at Windows 8.1 Start screen there was a down arrow on the lower left and when I clicked it I saw a list of installed apps. This screen, there is a lot of stuff here.
I also ran the appwiz.cpl cipals15 suggested and here is a screen shot of that. What I circled in red are items I installed myself.

Any obvious junk?
