(Redirected) should I do a windows 10 clean install with 64 bit OS?

Recently I did a clean install of a windows 10 using the media creation tool (I upgraded to10 prior to the clean install and used my product key). I noticed that it installed a 32 bit OS of windows 10. I believe my laptop has a 64 based processor and I'm wondering if I should have installed a 64 bit windows operating system instead of the 32 bit. I also wanted to upgrade my RAM memory, which now 6GB (2.40 GB usable). I have two sticks of RAM, one with 4GB and one with 2GB.

My questions are:

Should I do another clean install with a 64 bit OS of 10?

Is my laptop capable of doing this?

What is the maximum amount of ram this laptop can hold?

Thank you!
