A few weeks ago, Microsoft released Windows 10 Build 14342 to Windows Insiders. The build is currently available in the Slow Ring of the Windows Insider program. However, if you are planning to do a clean install, you will be glad to know that the official ISOs for build 14342 are now available. Over the weekend, Microsoft released the ISOs for Build 14342 and you can now grab it from the official Microsoft site. In case you are wondering: yes, the ISOs are available for the Enterprise, Education, and some other SKUs as well.
