Configuration Manager PXE guidance clarifies the RamDisk TFTP block-size setting

A single Configuration Manager documentation edit clarifies that the registry customization on PXE-enabled distribution points concerns the RamDisk TFTP block size, not the TFTP window size. This is a terminology correction in operating-system-deployment guidance; the supplied evidence does not indicate a changed default, registry path, value, or product behavior.

  PXE guidance replaces “TFTP window size” with “TFTP block size”

  In Prepare Site System Roles for Operating System Deployments, the instruction for customizing the setting on PXE-enabled distribution points now refers to the RamDisk TFTP block size rather than the RamDisk TFTP window size. The evidence supports a documentation clarification, not a confirmed product-setting change.
