Answer
Can you explain that a little better

You start out by saying browsers taking 40% on startup then you say without the browser being open.

What is a pb?

If you just talking about cpu usage at startup it's quite normal for cpu usage to be high as windows does a lot of stuff to get the machine ready to use.

If you just let it sit for 4-5 mins the usage settles back down.

as i turn my pc on and btw i have disabled most of the apps to launch on start up , google chrome or any browser that i'm using suddenly appears in the task manager and takes 40% of my cpu , without the browser being opened at the first place , and i have disabled prefetch and its still the same , and i have tried letting it go and see if it goes by its own or it decreases the usage but no it doesn't happen

I think windows "prefetch" may....

...contribute to that. It loads all the programs in background you commonly use into RAM so it can quickly present them to you if you want to use them again. You could delete the prefetch entries and see if that temporarily changes it, but it will just fill it up again as time goes on.
