most players are the same .I found wmp not that good. Are you listening to wave files ? Most are ok if playing cds but anything else and you get skips. Overall, my favourite player is real one, but none are perfect.
try setting uneeded services to manual or disabled to free up some resources if you think that may be whats causing it.
follow the advice click here "safe" list doesnt cause any problems for most people.just do one or two at a time after reading what each service is for.restart the computer to take effect.
also consider disabling some programs from automatically loading as windows starts to free up more resourses.
click start/run and type "msconfig" click the start up tab and look at whats starting.i would untick everything apart from your AV and firewall click here if you are unsure as to what you are changing and look it up.the programs will still function when you need them as normal,just not load with windows anymore.
