What Version of Windows Do I Have? Check Version and Build Number

About Windows Versions

As we all know, Windows operating system is the most popular computer operating system, which is developed by Microsoft Corporation.

So far, Microsoft has released many Windows versions for computer and mobile phone. The main computer operating systems for personal PC are listed as follows: Windows 95, Windows 98, Windows ME, Windows 2000, Windows XP, Windows Vista, Windows 7, Windows 8, Windows 8.1, and Windows 10.

It should be noted that Microsoft has stopped the technology support for many of the above systems except for Window 7, Windows 8.1, and Windows 10. In addition, Microsoft has announced that the technology support for Windows 7 and Windows 8.1 will be terminated in 2020 and 2023, respectively.

Apart from the different Windows versions, there are also different Windows editions. For example, Windows 10 has editions like Windows 10 Home, Windows 10 Pro, Windows 10 Edition, Windows 10 Pro Edition, Windows 10 Enterprise, etc. Apparently, each Windows edition provides users with different features and services.

After a Windows version is released, Microsoft will keep on developing it and provide updates for users. Each update may remove features, add features, or debug errors. In addition, each update carries a version number and a build number. Take Windows 10 as an example; current Windows 10 versions are shown in the following chart.

Many of you might have heard of 32-bit and 64-bit. Then, do you know the differences between them? Generally speaking, 32-bit operating system is designed for 32-bit CPU and 64-bit operating system is designed for 64-bit CPU. 64-bit operating system can’t be installed on 32-bit CPU, but 32-bit operating system can be installed on 64-bit CPU.

However, if you install 32-bit operating system on 64-bit CPU, the performance of the computer will be limited.

In theory, the performance and speed of a 64-bit CPUGPR (General-Purpose Register) is double that of A 32-bit CPUGPR. Additionally, 32-bit operating system only supports memory not more than 4 GB, but 64-bit operating system can break the limit.

If your CPU supports 64-bit operating system and the memory is more than 4 GB, 64-bit operating system is suitable for your computer. Otherwise, 32-bit operating system is more suitable for your PC.

Further reading: Not only operating system but also programs can be divided into 32-bit and 64-bit. 32-bit software can be installed on 64-bit operating system, but 64-bit programs are incompatible with 32-bit operating system. But unfortunately, 64-bit programs are less than 32-bit programs.

Nowadays, new computers basically support 64-bit operating system. Besides, some game players like to use memory not less than 8 GB; they should install 64-bit OS to make the computer perform well.
