How to Choose Between 32-Bit and 64-Bit Windows Operating Systems

The world has gone 64-bit, and there are many advantages that come with that, but one big question still remains - Which one is better - 32-bit or 64-bit? And, which one to choose? A 32-bit being the traditional one, 64-bit being the new microprocessor operating system which is more powerful, and more secure than the traditional one. The answers to these questions have been provided in this blog post.

If you want to install Windows from a disc, then you will have to choose between 32-bit and 64-bit operating systems.

32-bit operating systems are designed for older processors and are limited to 4GB of RAM. 64-bit operating systems can be used on all modern processors and support up to 16GB of RAM.

If you want to create a bootable Windows installer, then you will have to choose between 32-bit and 64-bit Windows installers.

Windows 10 is the most widely used operating system in the world. As Microsoft makes Windows 10 more and more secure, it is likely that you will need to create a bootable installer or install the OS from a disc.

The 32-bit version of Windows 10 will be available for download from July 29, 2016. You can create a bootable installer or install the OS from a disc only if you have a 64-bit processor. If you want to create a bootable installer or install.

The Differences Between 32-bit and 64-Bit Operating Systems?

32-bit Actually, 32-bit does not enable twice as much RAM when compared to a 16.77 GB physical RAM limit set by the system MAXIMUM addressable memory (PAGE_SIZE) in Windows x86 architecture. The 32 bit operating systems were introduced around 1995 and added support for multithreading of execution units and lower instruction latency through improved data path scheduling on older processors with 1366 available or faster cycles at clock speed of 33MHz. Also, 32-bit operating systems were designed to manage multiple threads and resources in user mode efficiently by combining the direct addressing capability which used a 16/33% segment (DS) base physical address space range with indirect page table pointers into 4GB (or 8KB). In Windows NT family of operating system environment, utilities when performing virtual function pointer calculations might return values that are larger than 64 bits thus causing memory corruption such as segfault or crash.

64-bit Windows 7 and above, thus 64 bit operating systems claims to provide increased performance by using larger pages in the addressing space which allows it to virtualize itself off (to become a process running on behalf of another). IT managers especially in high end enterprise environment needed this additional memory because each process runs independently requiring its own dedicated kernel workspace with permissions for I/O, execution units and data paths where all processes share the same page table. Moreover, a program can only access MAXIMUM 16GB RAM in multi-processor configuration by dynamically allocating pages to applications (via virtual memory). Although Windows has supported higher resolutions but it does not allow for very high number of them: see Memory limits.

Differences between 32/64 bit?  Yes.. VS HelloWorld C++ app will probably compile into 64 bits version if you are using Visual Studio. If you want to know more about differences between 32/64 bit OS refer Wikipedia .

So, how did I run my "Hello World" C++ app on Windows 7 64-bit when it's not supposed to be? First of all because Borland Intellisense (debugger) has the option of displaying warnings and errors which are different for 32 and 64 bits compiler architectures which triggers error messages about missing symbols at runtime in 64 bit executable. Those error messages are reported as warning which is made by MSVC if they see it's a 64-bit process environment and thus Microsoft Visual Studio VC++ compiler sets the following attributes on your application with an empty message:

#pragma warn disable Warning #1 (0 ms) : Project "C:\Users\Nico_>|taskbar\Website" does not contain project file C:\Windows\Microsoft.

64bit With this attribute you can set compiler/linker to explicitly ignore warnings about missing symbols which are also made for 64-bit Protected Mode processes. Run with -g level flag that 0 means "silent" and 1 is silent but still shows errors (some will not be silenced because they come from MSVC while others may cause show interrupt messages or other application instability). Intellisense should appear then :)

Warning: Project doesn't contain a project file. The launch/executable is located in 'C:\Windows\SysWOW64'

That's right the Windows development environment created by Visual Studio has a 64 bit process to bring up an application across between 32 and 64 bits platforms so it can be used on operating system with 4 different architecture support: AMD-32, IA-32, X86_Makes Intel x86(Generic) As you can see there are three different paths needed to start an application. The first one is the 32 bit executable found inside "program files" folder which defines only two subdirectories: bin (a target for executables belonging to a program) and obj (object code). In Windows Vista / 7 this directory is located in %PATH%; System32 or SysWOW64 respectively, on earlier versions it's in systemroot\System32 . While exception handling does not need to go here usually it does but anyway the second path is in root of your project.

And third one just files: linked on"Include directory (or an Include subdirectory)". While this paths are valid across all versions generally we can't distribute a EXE so use only "-I dir/src -c source_file.cpp because systemroot\include or "..\includedir" were not supported by Windows before but only by *nix.

Note: In some versions of Visual Studio the setup utility creates 3 different targets inside src directory but usually they're named like this 4th target example (based on where it's located in your project): \MultiContexts\Microsoft\CppCompile.

path to appear in other verions of VS you can check with "MSDN" page linked above. Please note that if running an application which was written in C++ without a 64 bit binary like Apache, Postgresql or MySQL then while it's good to have only two paths of code (the first one as indicated above), executing an application which is used externally which uses the same source code will run slowly mainly because on 32 bits platforms this path towards "msin" can be physically very long. The solution that I've been using for many years and surely some others were ending up with the same result but I wanted to share code as a way to make tutorials much more easier for all of you (even if this warrants a separate post). So here's how it works. First thing is that I'm using the comment blocks just like above. And in case your project has multiple functions with similar paths, e.g.: main () { # other parts } then you would go inside the description block: # File "main".

Should I choose 32Bit or 64Bit?

The constant evolution of computers and their hardware forever affects the way we perform enterprise operations. And, technological growth has led to the expansion of memory that makes it easier for developers to create programs that utilise higher amounts of memory. But a 32-bit processor is unable to utilise more than 4GB of memory.

1. The world's most popular Windows operating system has a better 64-bit version.

2. The 64-bit version of Windows is the best choice for most people.

3. You should always install a 64-bit version

4. 64-bit Windows will give you better performance and security.

5. If you have 32-bit Windows, upgrade to a 64-bit version as soon as possible.

6. For more information on the benefits of 64

7. There's no question that Windows 64-bit is the best choice for most users.

8. 64-bit Windows is the best choice for maximum security and performance.

9. Security - Protect your data with a strong, reliable OS that's built to last.

10. Performance - Get more done with better overall performance

It's always good to be up-to-date on the latest technology, so if you're thinking of buying a new PC, it's important to know that both the 32-bit and 64-bit versions of Windows are currently available. While a 64-bit version of Windows offers many benefits, such as increased security and performance, a majority of users don't need or use them. Therefore, if you're not sure whether you need a 64-bit version of Windows, it's best to choose the 32-bit version instead.

If you're buying a PC off the shelf, it will include a 64-bit copy of Windows. With a new PC that has a 64-bit version of Windows installed on a 64-bit processor, you're all set. However, if you're planning to build your own PC, choosing either a 32-bit or 64-bit version of Windows is an important decision.
