What is the minimum hard drive requirement for installing Windows 10 64-bit?

To install Windows 10 64-bit, the minimum hard drive requirement is 32 GB of available storage space. This specification is essential as it ensures that there is sufficient room for the operating system files, system updates, and any additional applications or data that may be needed after installation. Windows 10 is designed to utilize modern hardware features, and having at least 32 GB helps to accommodate the needs of the system effectively.

The other options pertain to different system requirements: RAM and processor speed, which while important for overall system performance, do not address the specific requirement for hard drive space needed to complete the installation. The choice of 200 GB is significantly above the minimum requirement, suggesting more storage than is strictly necessary for the install itself but not necessary to meet the basic installation criteria.
