The above mentioned partition size is the minimum partition size required for system installation.
Ensure that the partition size is sufficient for system operations.
The following partition sizes are recommended.
Desktop Experience
Server Core
＊ 1GB = 1,024MB
Note
 In Windows Server 2022, a recovery partition will be created after the
system partition. The system partition can not be extended because there is
no unallocated area behind the system partition.
Install Windows OS within sufficient partition size.
 The above paging file sizes are recommended for collecting debug
information (dump file). The initial size of the Windows partition paging file
must be large enough to store dump files.
Make sure you set a sufficient paging file size. If the paging file is
insufficient, there will be a virtual memory shortage that may result in an
inability to collect correct debug information.
 Regardless of the sizes of internal memory and write debug information, the
maximum size of the dump file is "installed memory size + 400 MB (installed
memory size + 1,800 MB when installed memory size is 4 TB or more)".
 When installing other applications or other items, add the amount of space
needed by the application to the partition.
If the partition size for installing Windows is smaller than the recommended size, expand the
partition size or add another hard disk drive.
