Win7 doesn't need any of them to run of course, but if there is an OEM feature that truly provides better monitoring or utility than Win7 native features then this is valuable information for users.
+1. Very true.
I would like to recommend to do a clean install on a new HP. I do it always. Get a naked (= not HP's with bloatware) Windows ISO or DVD and do a clean install, alternatively on newer models use the HP Factory Recovery selecting
Windows Only (the latest HP models allow user to select factory recovery to complete HP Setup (Windows & Bloatware) or Windows Only which according to my experience and notions is as close to real, fresh and clean install as possible).
Later do not install HP tools you think you need from any media delivered with your PC. Instead, go to
HP Support & Drivers, select correct country and language and using the product number from COA sticker search
Drivers and Software for the tools for your model. Notice that if the tool is not listed there it's not supported by your model.
Something
not recommended by HP but
wholeheartedly recommended by a user (me) who sets up at least a few HPs every year: Let Windows take care of your general device drivers. Last few years now since Windows 7 every HP PC I have set up, the Windows installation has found all the drivers itself. I do not remember when I have last time needed to download and install drivers from HP. If you feel you must have Catalyst Control Center or controls for Beats Audio or whatnot get them from respective device manufactures site, not from HP.
Another thing is the special drivers for system enhancements not needed for Windows to function, not shown as missing drivers in Device Manager because although the device exists it is only shown when device (or rather enhancement) driver is installed as Windows works perfectly also without it. I get two of this type drivers always from HP's Support page for respective models if they are supported: Intel RapidStorage and Intel TurboBoost.
Bloatware and crapware are a bit too general terms. One man's crap is other man's gold. For me the three tools I mentioned in my previous post are if not gold but copper at least
