Windows 10 and Office Excel

Reverse the process
2 simple steps is all that is needed using the Windows user available control system management to undo what we just did.
_ 1 Delete the volume we just created:

The volume is then back in its "Not assigned" state. Because it has not been assigned it no longer is shown in the typical explore computer window, but the original ( C: in our case) drive is still limited to the shrunk size:

The "empty" space is now spare, it is no longer being seen as an effective separate entity.
_ 2 extend the volume
One final step effectively extends the C: space back to enclose most of the available space on this physical drive. Right click on the still shrunk bit and chose the option to extend:

A "Wizard" Window comes up , and if you leave all the default options and keep clicking "Next" then you will end up back at the situation before we started doing any partitioning.
