I found this thread that says how to delete GRUB2 Uninstalling GRUB from UEFI laptop

But I'm not sure if it applies to me or if I'm doing the things correctly, I'll attach a few screenshots about the contents of EFI Partition and I would appreciate if you guide me what to delete and what to rename, I want to remove GRUB2 and restore the Partition to the original state (It came with Windows 8.1 pre-installed).

According to the thread, deleting the Ubuntu and GRUB folders should be enough, but I feel it won't be enough since there are weird things like /EFI/EFI/Ubuntu (Why two folders with EFI?) /EFI/Boot and EFI/EFI/Boot, etc. you will see in the pictures but my instinc tells me, deleting won't be enough... :s

Here I uploaded the screenshots, please take a look at them:

Thanks for your attention :)

If you haven't modified anything in \EFI\Microsoft (as it looks to me), then deleting the ubuntu folder next to the Microsoft folder should be sufficient.

(If you have modified the contents then you should overwrite the Microsoft directory with Windows' bcdboot, have a look at the related section for instructions.)

Regarding the confusion about the EFI folders:

mount | grep efi
none on /sys/firmware/efi/efivars type efivarfs (rw)
/dev/sda1 on /boot/efi type vfat (rw)

As you can see in the example from my system the ESP is mounted to /boot/efi/ and itself contains an EFI folder. This is how it should be by default and you don't need to delete anything outside of /boot/efi/ as this doesn't belong to the ESP.
