i know windows can be a little bloated but 222GB seems a bit extreme for just windows... my windows 10 folder is around 20GB plus the default program files folder adds a little more but shouldn't be anywhere near 50GB let alone 200GB...
if you're running windows 10 (i assume you are), press the windows button and type in "storage settings" , open the setting it gives you and click "show more categories" - let it update its readings and it'll give you a better understanding of what is using your HDD
you can click each section to open a more detailed info page too
