If you do not need your recovery environment you can stop here and enjoy your new disk space. However I highly recommend recreating the just deleted recovery enviroment. That way in case of a system failure you can easly troubleshoot and restore your system. To create a new recovery partition we first must format the remaining 500MB free space accordingly. Windows recognizes the recovery partition by the static unique id de94bba4-06d1-4d40-a16a-bfd50179d6ac and the GPT attribute bit 0x8000000000000001.

DISKPART> create part primary

DiskPart succeeded in creating the specified partition.

DISKPART> format quick fs=ntfs label="Recovery tools"

100 percent completed

DiskPart successfully formatted the volume.

DISKPART> assign letter="R"

DiskPart successfully assigned the drive letter or mount point.

DISKPART> set id="de94bba4-06d1-4d40-a16a-bfd50179d6ac"

DiskPart successfully set the partition ID.

DISKPART> gpt attributes=0x8000000000000001

DiskPart successfully assigned the attributes to the selected GPT partition.

DISKPART> list volume
DISKPART> exit

We now have a partition that can host the Windows Recovery Environment (WinRE). In the next step we are going to extract the WinRE from the Windows Installation media and copy it to the just created volume.
