So, prior to proceeding the steps described below, find out what architecture is used on your computer.

And the unallocated space appeared after the second recovery partition (labeled as Windows RE). When I opened the Disk Management console (diskmgmt.msc), I noticed that there were two recovery partitions on the drive.
I increased the disk size in the virtual machine settings and switched to the guest OS (Windows 10) to extend the size of the system partition using the unallocated space. Once I saw that one of my test virtual machines was running out of free space on system drive C.
