Installation Guidelines

• Plan ahead. Back up your files and settings before installing this evaluation.
• Upon installation, Windows will prompt you to activate. A product key is not required for this software.
• In order to use Windows 10 Enterprise, you must sign in to your PC with a Microsoft account. The option to create a local account will be made available at the time of the final release.
• If you decide that you want to install Windows 10 Enterprise using one of the provided ISO files, you won't be able to uninstall it. In addition, after you install Windows 10 Enterprise, you won't be able to use the recovery partition on your PC to go back to your previous version of Windows. A clean installation of your former operating system will be required, and you will need to re-install all of your programs and data. 
• If you fail to activate this evaluation after installation, or if your evaluation period expires, the desktop background will turn black, you will see a persistent desktop notification indicating that the system is not genuine, and the PC will shut down every hour.

Things to Know

• Windows 10 Enterprise should work with the same devices and programs that work with Windows 8.1. In some cases, a device or program might not work or may require an update, or you might need to uninstall some programs and then reinstall them after installing the evaluation.
• Downloading Windows 10 Enterprise could take a few hours. The exact time will depend on your provider, bandwidth, and traffic (ISP fees may apply).
• For the latest information on deprecated features and additional requirements to use certain features, please see Windows 10 computer specifications. For technical questions, please visit the Windows 10 Tech Community.

Verify Download

If you would like to verify the data integrity and authenticity of your download, you can follow these steps:

1. Download the desired product ISO file under Get started for free and follow the installation guidelines.
2. Launch Windows PowerShell. If you need help finding the location of PowerShell for your operating system, you can get help here.
3. In PowerShell, compute the hash value for the ISO file you downloaded by using Get-FileHash. For example: Get-FileHash C:\Users\user1\Downloads\Contoso8_1_ENT.iso
4. If the SHA256 output matches the value for the product that you downloaded shown in the table below, this confirms that the file has not been corrupted, tampered with or altered from the original.
