Can I downgrade from W10 to W8 and upgrade later again?

[Windows Central Question]

I upgraded to W10 about a week ago, and it's been causing me more trouble than W8 since I got my laptop. My computer's specs are more than enough to run W10 by the way. I'm tired of looking for solutions and I'm going to downgrade to W8, my previous OS. Can I upgrade again when Microsoft have released enough patches to make W10 work?
