Is there any way to take advantage of this space or is it lost to me? Below is a picture of Disk Management

You can use the Diskpart command to delete the Recovery partition and then, of course, use Disk Management to invoke the Extend Volume command to extend your C: partition to encompass the resultant unallocated disk-space.

The basic Diskpart final command you will use after invoking/using Diskpart and selecting the Recovery partition is delete partition override. You should get the message "DiskPart successfully deleted the selected partition."

I don't know if you're familiar with using Diskpart. If you're not, do a Google search - there's plenty of information re using this valuable tool.

Given that your C: drive is right at 2048 GB, the drive is probably formatted as MBR. MBR only supports a maximum 2 TB partition size. So even if you moved the recovery partition to the end, you wouldn't be able to combine the 746 GB free space with the C: drive. (Actually, you can probably just delete the 450 MB recovery partition. According to the top of your pic, it is empty. And 450 MB isn't enough to store recovery info for any modern version of Windows, so your installation software probably screwed up making this partition.)

If you want, you should be able to create a 746 GB partition in the unallocated space. MBR supports up to 4 primary partitions on a disk, and you've only got 3. So you should be able to make one more. Just right-click it and select create partition. (Or right-click the 450 MB recovery partition, select delete. Then right-click the unallocated space and select create.)

If you want to combine the extra 746 GB with your C: drive, you will need to convert the disk to GPT. There are tools out there that claim to do that without data loss, but you use them at your own risk. Backup your data first, and do it over the weekend because worst case you're going to have to reinstall Windows on the drive.
 
The drive is GPT. There is no option to delete the recovery partition. It simply does not show up when right clicked or selected above.

The unallocated space (and the reason I made this thread), when right clicked, has the "New Simple Volume" option grayed out.

I would love to learn how to move or delete that recovery partition to allow me to utilize the unallocated space.
