Problem with include files

I am running VS 2022

In C:\Program Files (x86)\Windows Kits\10\include\10.0.22000.0\um\winbase.h:

    // Structure Version
    USHORT StructureVersion;     // 1 for Win7, 2 for Win8 SMB3, 3 for Blue SMB3.
    USHORT StructureSize;        // sizeof(FILE_REMOTE_PROTOCOL_INFO)

    ULONG  Protocol;             // Protocol (WNNC_NET_*) defined in winnetwk.h or ntifs.h.

    // Protocol Version & Type
    USHORT ProtocolMajorVersion;
- - - - - -

After running through the preprocessing pass of the compiler:

#line 9106 "C:\\Program Files (x86)\\Windows Kits\\10\\include\\10.0.22000.0\\um\\winbase.h"

    USHORT StructureVersion;     
    USHORT StructureSize;        

    ULONG  "protocol";             

    USHORT ProtocolMajorVersion;

!!!NOTE THE CHANGE FOR Protocol!!!

This results in the following compile error:

C:\Program Files (x86)\Windows Kits\10\include\10.0.22000.0\um\winbase.h(9113): error C2143: syntax error: missing ':' before 'string'

- - - - - -

   This is due to the fact that somewhere there is:
 #define Protocol "protocol"
   This is bad practice. Preprocessing definitions should be all upper case. If
   I were writing this I would have had:
 #define PROTOCOL_STR "protocol"
   and have used that as needed. Not following this style resulted in the error
   here. But what do I know, I'm just an old school programmer with over 40
   years of experience.

  To get past this I cracked the file permissions and edited winbase.h changing
  'Protocol' to 'Protocol_'
  I didn't like doing this but there was no alternative.
  This resulted in a successful compilation.

This should be corrected.
