In early versions of Microsoft Windows, the local drives on a computer were assigned drive letters alphabetically, starting with A and B. The A: drive was used for floppy disk drives and the B: drive was reserved for an optional second floppy disk drive.
When hard disk drives were introduced, they were typically assigned the next available drive letter, which was C. This became the standard practice and has carried over to modern versions of Windows.
Almost all of us have now accepted the “C” drive as the default Windows installation location. In fact, all the new programs are by default installed on this drive.
It is worth noting that it is possible to change the drive letter assignment for a device in Windows, but the C: drive is typically reserved for the system drive, which contains the operating system and other essential files. Changing the drive letter for the system drive can cause problems with the operating system and should be avoided.
