https://lists.01.org/pipermail/edk2-devel/2017-August/013488.html These fields are actually a GUID and DWORD respectively: the GUID identifies the PDB to make it possible to verify that a given PDB matches the PE file, and the DWORD is the "age" of the PDB which is simply a helper value that is incremented by 1 by the linker every time the file is remade. Wiping the GUID will cause PDB parsers (such as the MS DIA SDK that IDA and most other tools use) to treat the PDB as a mismatch and refuse to load it.
