|I may be too late to advise but download Autoruns from Microsoft. It is a stand-alone program. No need to install.|
Do not uninstall programs in a hurry. Run Autoruns and just uncheck the checkboxes of startup pograms first, which start automatically when Windows starts.
I assume you can identify what the programs whose checkboxes you uncheck do. Otherwise, you may make your machine unable to boot.
After some time of usage, you will see that you do not need some of the programs. Then you decide if you really want to uninstall them or not.
I understand this is a brand-new laptop. It needs some time to adapt to your usage of the programs. It has superfetch, prefetch, etc, that work together to make your computing experience a lot better.
Also install all Windows updates along with Service Pack 1 and defrag the hard disk afterwards.
Putting more RAM will help, too.
