You can use a tool like HashMyFiles to check this information. Unlike ISO files generated from the ESD, this Install.ESD will always remain the same. However, in the interests of expedience, a valid ISO file has been created. The operating system is governed by Microsoft's END-USER LICENSE AGREEMENT. You may not be able to activate the build of Windows 10, and no license keys can be provided. If you were not a member of the Windows Insider Preview Program, you may not be able to activate this build. PRE-RELEASE KEYS WILL NO LONGER ACTIVATE BUILDS. Therefore, in addition, clean installing with an ISO might actually be pointless at this time. This ISO file distribution is mainly designed for our members and technical experts.
