Thanks for the info. On step 9 of the guide you linked, in that window, under Disk Space Usage mine says Current Usage: 0 bytes. haha! If I'm using 0 bytes then why is there only 5gb free? I'll turn it off anyways. Assuming it's safe to disable system protection for C drive if I'm not going to keep much of anything on this computer.. it warns not to, but, meh.
