As Windows 10 is still a pre-release software, chance is that the bugs found in earlier builds may be carried forward to the latest build. So some may want to perform a clean install to get a fresh start. In addition, the support of Cortana, the Microsoft’s virtual assistant, has been expanded to Windows Insiders in China, UK, France, Germany, Italy and Spain plus the US. However, users cannot easily switch to one of Cortana’s new supported languages in build 10041, where the easiest way to workaround from users who came from Build 9926 seems to be a reinstallation, where the ISO image will come in helpful.
The updated ISO images of Windows 10 Technical Preview has also been released by Microsoft alongside the Slow ring deployment, where they contains Windows 10 Build 10041, a major jump from previously available ISO images which contains Windows 10 Build 9926. Microsoft is also calling the new ISO images “March Update”, and they are available to download now from the Windows Insider site.
