i want to upgrade to windows 10 pc, so do i have to transfer my existing files on C:/ and D:/ Drives or is it going delete every files from my pc while upgrading process?
I upgraded and none of my files disappeared and for the vast majority it\’s the same. however, for a few individuals, their data was erased. So i would recommend that you copy your important data to an external drive or upload to onedrive. Just the important stuff that you can\’t afford to lose. For that just in case scenario that has a 0.1% chance of happening
