Microsoft has launched Windows 10 20H2 beta and Windows 10 21H1 beta. The above versions will be released this fall and next spring.
The current testing stage is mainly early testing, so there may be many stability issues. In principle, it is not recommended to use the beta version to avoid affecting normal use.
However, it is possible to install the beta version in the virtual machine for a preliminary experience. Now Microsoft has released Windows 10 Insider Preview Build 20150 ISO image file to make it easier for us to use the virtual machine experience.
