Do I have to go into each one individually and do this
No. I think I mentioned before that if your device manager is not showing any errors, then don't just randomly try updating drivers unnecessarily. It may result in a driver being installed from Windows Update that is less than optimal for your devices. HP is generally going to be your best bet for drivers. If they don't have any currently, then you can check back occasionally to see if any have been added.
The HP Support Assistant will generally advise you regarding "Messages" as well as "Updates" from HP.
The HP Utility that I was talking about is that "Check Now" button on the site that is suppose to scan your computer for any needed device drivers specifically for it.
The HP Support Solutions Framework is the underlying service that supports the HP Support Assistant.
If your printer is working.... don't mess with it.
The InPrivate browsing mode for Internet Explorer automatically disables extensions, plugins, addons, etc. IF you find that your browsing experience improves using that mode, then....
That suggests that you have some extensions or addons that are causing problems and you need to uninstall them or minimally disable them.
You can click the gear in the top right corner of IE when you launch it normally (not InPrivate) and choose Manage add-ons.
