Welcome to the forum.
I am not a HP employee.
Hi, I am looking at your PC's specs and I see a 16 GB SATA SSD and a 2 TB platter HDD.
What's going on?
The 16 GB SATA disk caching drive is normally hidden in Windows Explorer. So the "C" drive should be the 2 TB HDD. Windows is installed on this 2 TB drive.
The "D drive is normally the HP Recovery drive.
Why do you want to swap drive letters?

You're very welcome.
Did you use HP Recovery software to reinstall the operating system on the new HDD? It sounds like you may not have done this if the 16 GB SATA SSD is visible in Windows Explorer.
You need to install the HP provided Condusiv ExpressCache application (Link) to get the 16 GB cache disk working as HP intended.
It is not possible to change drive letters (as Echo_Lake stated) within Windows because the operating system drive is locked.
You may be stuck with the "D" drive issue until you reinstall Windows using HP Recovery media or, the condusiv ExpressCache update may fix this problem. Try this update. Then reboot Windows to see what happens.

I forgot to add that changing operating system drive pointers will also cause havoc with every program you have installed on your PC.
You may want to start from scratch using HP factory recovery media.
Back up data before proceeding.
