I think the restriction is even stricter: you can't map readonly executable memory either.

I looked through:
http://msdn.microsoft.com/en-us/library/windows/apps/br205762.aspx

And as far as I see there are no analogues of VirtualAlloc, VirtualProtect and CreateFileMappingFromApp (analogue of CreateFileMapping) allows only PAGE_READONLY, PAGE_READWRITE, PAGE_WRITECOPY values for PageProtection parameter. The same for MapViewOfFileFromApp (analogue of MapViewOfFile): DesiredAccess can only be FILE_MAP_ALL_ACCESS (read/write), FILE_MAP_COPY, FILE_MAP_READ, FILE_MAP_WRITE. In both cases executable options are missing _entirely_.
