I was just pondering

I am a farmer with no techie knowledge and would like a couple of questions answered.I would like to get a new windows for my computer.
Why is it so expensive,it’s rediculas?
Why are all techie guy’s so boring and geeky who will not give me a straight answer?
How do i remove a linux partition?
Why is linux so rubish?(my husband put it on the computer).
Do you guy’s know where i can get a free windows , i dont mind downloading?
