One for you Microsoft types. Please don't guess if you don't "know"

I have a PC running Windows 8. I've recently added an extra physical drive. The original drive is partitioned as two logical drives.

So
drive #1P0 = C: ----> C:
drive #1P1 = D: ----> X:
Drive #2P0 = Y: ----> D:

I want to end up with drive #2P0 as D: Eventually I'll repartition #1 as a bigger C: and use X: as a physical backup for some critical files on the new D:

Now then.... Switching drive letters is dead simple but I'm not sure if the apps and OS reference the drive by letter or partition. eg,

If I shift content from D1P1 D: to D2P0 Y: then reassign the drive letters will the apps happily now look on D2P0 because it's now labelled as D: or will it still look on D1P0 even though that is now tagged as X:

Can't just do a partition shift to the new spindle as I've got other stuff on the current Y: that I want to keep that's too big to temp shift elsewhere.

Anyone know for sure?

Then I need to have a fight with ITunes about moving and merging libraries which is likely to get a tad frustrating.
