not sure what you mean by system configuration??
whenever i get a new puter, install windows from fresh or fix somebodys puter i always stop as many programs from starting as i can, it hogs resources having lots of processes and programs running that you dont need to
how do i do that?
start menu/programs/run/msconfig in windows now you may have to add the run dialogue box yourself by right clicking on the start menu and selecting properties/customise (in windows 7 and below anyway)
click and open the run menu and type msconfig click on startup
right whats safe to stop from running? almost everything tbh, specially stuff like adobe, nero, itunes, quicktime, java etc any other program names / vendors you know
what do i leave?
my security software, in my case commodo and avast, i leave them ticked
also
anything that looks like it might be for my motherboard, especially graphics etc
in this case the programs dont get deleted they still work, they just get disabled from automatically starting when windows boots up, if i need say adobe i click it when i want it, not when they say it should run
if youre confused or need other info i dont come on this site often but leave a message, ill see it eventually lol
