As Windows 10 systems continue to change with new features and more space, Microsoft is gradually increasing hardware requirements. According to the minimum hardware requirements page from Microsoft, the disk space requirement for Windows 10 v1903 has been increased to 32GB, if the system storage space is lower than 32GB, it will directly report errors during installation.
At the same time, both 32-bit and 64-bit operating systems require at least 32GB of hard disk space. In the past, Windows 64-bit hard disk space requirement is relatively higher than 32-bit. For example, in Windows 10 Version 1809, the 64-bit minimum hard disk space requirement is 20 GB, while the 32-bit version requires only 16 GB space.
The minimum hardware requirements for Windows 10 IoT specials are unchanged. The minimum hard disk for the 64-bit system requires 20GB and the 32-bit version requires only 16GB. The hardware requirements of other versions of Windows 10 devices are basically not changed much, and the minimum resolution requirement is 800*600 to run normally.
