that's better - now you need to test your software to make sure it still works. if it doesn't it's easy to re-enable the startup entry.
personally, i like to be ruthless with these and like to eliminate as many as possible without damaging my system.
i can't see all the text and names, as the columns are too narrow, so i'm guessing a bit here.
the hd audio can possibly be disabled - check that your sound (and control panel) still works after doing so!
the 'default settings' ive never seen before - column too narrow to read
the three intel entries - i think these are to do with the intel graphics - i've always disabled these in the past with no bad consequences.
the first microsfot one looks like microsoft security essentials - obviously do not disable this one!
second microsoft one, i can't see.
finally does poweriso still work after disabling? or do you need iso's auto-mounted at startup.
as for the ones you've already disabled - a lot of them are just updaters, which check for new versions of software at each boot time.
make sure everything still works - if not, it's really easy to re-enable.
*edit* looks like you've disabled a microsoft security essentials - 4th one down right-hand side - you may want to enable this one again. not sure why you have two entries for this. did you update without uninstalling or something? enable the malware bytes again too!
*edit2* also - don't forget that you've done this! in 6 months time, when something isn;t working as expected, it could be that you've disabled the wrong thing.
