UPDATED 10/21: The Windows 10 minimum system requirements has changed since version 1903, May 2019 Update. Although the changes aren’t significant, starting with the seventh feature update and higher (including version 1909), the minimum storage requirement increases to 32GB, but this is only for new devices or if you’re trying to perform a clean installation of the 32-bit or 64-bit version of the OS. However, if your computer has less than 32GB, and it’s already running an older version of Windows 10, then it’ll continue to upgrade without issues (if enough space is available for the update).
The reason for the new storage requirement is set to leave space to install apps and keep data on the device. Also, starting with the May 2019 Update, Windows 10 introduces Reserved storage, a new feature that is meant to reserve part of the available storage for updates, temporary files, system cache, and apps.
These are the system requirements to run Windows 10 version 1903 and later (including version 1909) on a desktop, laptop, or tablet:
In addition, starting with the May 2019 Update and November 2019 Update, Microsoft is slightly updating the processor requirements to support the 10th Generation processor from Intel and AMD Ryzen 3xxx series chips. Also, the Qualcomm Snapdragon 8CX is making its way to the supported list, which happens to be processor, plus some custom modifications, that the company is using for Surface Pro X.
This is the second time that Microsoft is updating the main hardware requirements for Windows 10. Previously, the company increased the minimum requirement of memory to 2GB for the 32-bit version with the Anniversary Update.
