32-bit can be more suitable for 4GB RAM (3.5 usable) compared to 64-bit Windows 10, depending on your needs.

Windows systems support only 32-bit or 64-bit applications depending on the version. While a 32-bit OS restricts you to 32-bit programs, a 64-bit version lets you run both 32-bit and 64-bit software. Some tools let you choose between the 32-bit and 64-bit installer if memory savings are crucial. In practice, 64-bit apps typically consume 10-20% more RAM than their 32-bit counterparts, which is usually negligible. Today many programs are built for high memory use, such as Google Chrome, and you might find 32-bit versions of browsers like Firefox—but they could perform worse than the full 64-bit options.
The 64-bit edition requires additional memory, encompassing both regular and high-performance applications. The total could be insufficient, but that shouldn’t be a big issue. If your usage reaches around 3.5 GB, you’re likely nearing the 4 GB threshold.
You would execute 32-bit on older systems lacking 64-bit support, either due to driver or CPU constraints. Running 32-bit also allows 16-bit programs if needed for compatibility. In most cases, opting for 64-bit provides stronger security and a larger address space.
When deciding between 32 and 64-bit operating systems, opt for 64-bit whenever possible. This choice goes beyond just memory constraints—it also affects software compatibility. For example, Apple’s Catalina removed all support for 32-bit systems completely. It’s unlikely Windows will follow suit soon, but developers might prioritize 64-bit solutions. In gaming, many titles require 64-bit platforms to run properly. If you intend to use your PC for tasks beyond basic browsing, avoid restricting yourself to a 32-bit system.
