2-3 year old Dell laptop I bought used. I upgraded to Win 10 on release day early that day AM eastern time. PC was shipped with 8.0 and than updated to 8.1 prior to me purchasing it. I just saw that I have 7 partitions after I was digging around on the PC. Is this a factory thing or did the prior owner make a bunch of partitions. I've owned the PC a while now again ever since Win 10 first release to the public. It is running amazingly fast for a 2-3 year old PC. I keep it maintenanced and I'm protected from malware and other various threats.
Here are the partitions listed in order
Healthy - EFI System Partition - 500 MB and 500 MB free
Healthy - OEM Partition - 40 MB and 40 MB free
Healthy - 490 MB and 490 MB free
Healthy - 475 MB and 475 MB free
Healthy - 450 MB and 450 MB free
Healthy - 11.69 GB and 11.69 GB free
Healthy (Boot, Dump, Crash, Primary Partition) - OS (C NTFS 284 GB and 46 GB free
This is kind of a surprise as I haven't done any custom backing up. I'm pretty safe with my PC so I'm only using System Restore and nothing else currently. So I really need help if I can. If I can remove these or keep 1 for whatever I really want this HD space back. Thanks in advance and FYI I have done partitions on SD Cards for android phones. Nothing on PC though. I'm not a PC noob. I consider myself a intermediate enthusiast and I've never had to take a PC to a professional. I am a noob when it comes to partitions on a PC however. So I have no idea what should be there and what shouldn't be there.
