1. Find out what each program you have installed does and evaluate if you need/want it. Get admin of computer do some admin work.
HP Support Forums - HP Support Forums
2. Update drivers per HPs advice/suggestions - with possible changes from HP user forum, experience beats updates any time. Why the hesitation? If you can untick what you don't need you can also update drivers. It is as much HPs computer as it is yours - ever heard of PC Decrappifier? Computer is supposed to work out of the box - at least after updates.
Very possible you have some hanging cam, wifi, network adaptor whatever driver hanging, don't know.
Might be worth investigating "QuickPlay Background Capture Service" at Google,
Service QuickPlay Background Capture Service (QBCS) hung on starting. - Notebook Forums and Laptop Discussion for example look interesting but again it does not matter if whatever bug is fixed long ago and you wont update.
Seems like there was some Norton stuff in bundle but you disabled and went for Avira?
Speaking of drivers you seem to have Driver Genius installed, did that come with HP bundle? If not what you use it for?
Don´t think computer is infected - overloaded perhaps. "Free Easy Burner V 3.8" computer would not be the same without?
May be good uninstall list is cut off.
Do some trial and error - starting with cam stuff, moving on to network. Definitely update first or you could be wasting time.
Not sure it helps but try open event viewer, go to Applications and Services Logs, Microsoft, Windows, Diagnostics-Performance, Operational. A million thing cause "slowdowns in the startup process" but may be something stands out - like a non Vista process? Sort by Event ID, focus on 1xx - is there a pattern?
