my laptop became a bit slow and explorer crashes often. So, to clean install, I am guessing "Reset this PC" should work. There are 2 options "Keep my files" and "remove everything". I have partitioned the hard drive space it to 4 local disks and installed windows 10 on C drive. I want only C drive to be cleaned and rest of the disks data to be intact. Which option to choose?
Additional Info: My laptop came with Windows 8 and I upgraded to W10. So I am hoping this reset option wouldn't mess with activation.
