I had some issues with one of SSDs that was used as the boot disk(missing bootmgr, probably corrupt files somewhere), it was formatted in RAID0. It didn't work so I deleted the RAID. Short story is that it wasn't working so I reinstalled Windows onto a different SSD. When I got into it the windows files were still on the old SSD and the apps worked. However I already re downloaded windows and don't need any of the files. My main question is, is it ok to just mass delete all the files, because Windows thinks since it has some boot files they are important but I'm never gonna realistically use the files. It is just a waste of 30+Gb. I'm worried that somehow Windows might screw something up when I delete them.
