Hello folks,

retested some Windows Sysinternals (former "Sysinternals") tools.

Whoops, that structure type/layout seems wrong...

entry_DESKWALLPAPER:

--- snip ---
struct sysparam_entry
{
    BOOL       (*get)( union sysparam_all_entry *entry, UINT int_param, void
*ptr_param );
    BOOL       (*set)( union sysparam_all_entry *entry, UINT int_param, void
*ptr_param, UINT flags );
    BOOL       (*init)( union sysparam_all_entry *entry );
    const WCHAR *regval;
    const WCHAR *mirror;
    BOOL         loaded;
};

...

struct sysparam_path_entry
{
    struct sysparam_entry hdr;
    WCHAR                 path[MAX_PATH];
};

...

#define PATH_ENTRY(name) \
    struct sysparam_binary_entry entry_##name = { { get_path_entry,
set_path_entry, init_path_entry, \
                                                    name ##_VALNAME } }

...
static PATH_ENTRY( DESKWALLPAPER );
--- snip ---

Typo in PATH_ENTRY macro: "struct sysparam_binary_entry" should be "struct
sysparam_path_entry".

With that fix in place "bginfo" doesn't crash anymore.
Probably fixes other apps too ...
