Windows 10 version 1507, also known as the initial release or the RTM (Release to Manufacturing) build, marked a significant step forward when it launched in July 2015. This version was quite a shift from Windows 8.1, bringing the reintroduction of the Start Menu, which blended live tiles and a more traditional layout that many users missed in Windows 8. It also introduced features like Microsoft Edge as a new browser replacing Internet Explorer, Virtual Desktops, and the Action Center, which centralized notifications and quick settings.
However, compared to the current Windows 10 versions, 1507 lacked several features and improvements we've come to rely on. Over time, Microsoft has rolled out several updates focusing on security, performance, and new functionalities. For instance, later versions introduced features like Windows Defender's gradual evolution into a robust security suite, the Windows Subsystem for Linux, and improved Cortana capabilities, among others. The evolution of the Settings app to better organize and manage system configurations more intuitively is another significant change.
As for trying out version 1507, it might not be that practical for everyday use today. Many newer applications may not support or function optimally on it. Additionally, Microsoft no longer supports 1507, which means it's not receiving security updates, making it potentially vulnerable to threats. Learning about 1507 can offer interesting historical context regarding the evolution of Windows 10 but using it as a stable operating system isn't advisable due to security and compatibility issues.
Anyone interested in the development of Windows could certainly benefit from examining how the OS has evolved, but for practical purposes, sticking with a more updated version is recommended. Keeping your system up to date ensures you have the latest patches, features, and security enhancements. If you're curious, Microsoft offers a lot of documentation on the changelogs that highlights what has been changed and improved with each major release. It's a good way to keep up with how the OS has evolved over the years.
