Pre-installed lenovo apps?

Can i remove pre-installed lenovo apps like lenovo reachit? Or if i change my computer and login with the same microsoft account with a computer with a different manufacturer, will lenovo apps be still installed?

P.S if i buy a new computer, how can i transfer my data like my settings and changed pointers etc. Or install all the apps i had before in my old computer automatically?

Yes.
No.
Transfer by using the same MSA account. NOT everything wil be transferred.
You can't install all your apps automatically. If you have downloaded the apps from the Windows Store, they will all be available to you - and will probably have the icons on the new PC, so all you need to do is to click on the ones you use.
