When I upgraded from Windows 7/8 to Windows 10 and cannot increase the size of my virtual machine disk.

After I increased the hard disk space by following KB 113972, the Windows disk size remains the same as it was before increasing it in File Explorer.

If I open Disk Management ( Start button > type diskmgmt. MSC > hit Enter (Return) ), I see that the last partition on the disk has been increased instead of the C:\ partition:

Parallels Desktop increases the space of the last partition in a list. This is a default Windows behavior. To increase the size of a desired partition, you should use the Diskpart program.

To add space to the C:\ partition you need to remove the last partition that was extended by Parallels Desktop:

Right-click Start button, then click Command Prompt (Admin).

or

Click Start button and type Command Prompt then right-click on the suggested item Command Prompt > select Run as administrator.

Open the DISKPART utility by executing the following command:

4. Navigate to required partition and remove it:

where <#> is the number of the Recovery partition:

5. Navigate to the required volume and extend it:

6. When the operation is finished, the following message will be displayed: DiskPart successfully extended the volume.

7. To make sure the operation was completed successfully, open File Explorer in your Windows virtual machine and check the size of the C: partition.
