The minimum HDD requirement for Windows 10 64-bit edition is 20GB.

• A. 16GB
• B. 20GB
• C. 32GB
• D. 64GB

Answer: (B)

The minimum disk space required to install Windows 10 64-bit is 20 GB. This is the official baseline Microsoft specifies for the 64-bit edition, representing the space needed for the installation files and the resulting system files. A smaller amount, like 16 GB, isn’t enough to fit the OS, so it would fail to install. Larger numbers such as 32 GB or 64 GB exceed the minimum, but the question asks for the minimum required. Remember, after installation Windows will use more space for updates, system files, and apps, so it’s wise to have more free space than the bare minimum.
