Compare Windows 10 64-bit and 32/64-bit versions.
The first product is a Windows 10 SKU 900016, while the second is SKU 900139. The main difference lies in their release dates and possibly minor hardware or software updates between them.
The question seems a bit unclear, but it appears you're asking whether the system supports both 32-bit and 64-bit features while offering unique backward compatibility aspects compared to the 64-bit version. With at least 16GB RAM, you may want to explore if older software runs smoothly or if there are special optimizations available in either architecture.
Only a single installer exists for both 32 and 64-bit configurations.
