Microsoft released tools: Win7/8.1 can be upgraded to Win10

Computer store news: Microsoft's next-generation operating system Windows 10 technology preview version was released in October this year, and in 2014, it is nearing completion. Recently, Microsoft released a small tool that can help Win7/8.1 users upgrade their systems to the Windows 10 Technology Preview.

This is great news for users who are eager to try Windows 10 Technology Preview without installing an ISO image. This tool will allow your Windows 7/8.1 system to upgrade your system to the latest Windows 10 Preview in the upcoming 2015.
Of course, as always, the Windows 10 Technology Preview also has the lowest configuration requirements. If your computer does not have a 1Ghz CPU, or if the hard disk space is less than 16GB, you will not be able to get updates. Open the tool, you will see the following message: Win7/8.1 can go directly to Win10

Of course, if you don't want to wait, you can also experience it in advance through virtual machine software such as VMWare. This application will not be your computer itself. The system constitutes interference.
