When I remove '*.dll binary" from .gitattributes, I get this:

$ git check-attr --all ./PSWindowsUpdate.dll
./PSWindowsUpdate.dll: text: set
./PSWindowsUpdate.dll: eol: lf



When I add "*.dll binary" to .gitattributes, I get this:

$ git check-attr --all ./PSWindowsUpdate.dll
./PSWindowsUpdate.dll: binary: set
./PSWindowsUpdate.dll: diff: unset
./PSWindowsUpdate.dll: merge: unset
./PSWindowsUpdate.dll: text: unset
./PSWindowsUpdate.dll: eol: lf


I can also confirm that there are null bytes in the first 8k bytes.
These are the first 16 bytes
