i dont know much about pcs so i thought id ask for help here.
iv been noticing my pc is abit slow latelly, and i think its because my windows startup has too many programs activated. i made a search on the internet and found how to de-activate them (start-run-msconfig.exe), but then i honestly have no idea wich itens to check or not cause that all looks like chinese to me i tried the net again, and found a site with a list of required and not required aplications at the startup, but i dont want to touch anything and then "POOF", and i lose everything on my pc lol so can anyone help please? i'd like to know if that site is reliable and if not what can i do...?

thnx and sorry if my english is not the best but my brain doesnt work well at 2am (almost lol)
