Reinstalling and Upgrading OS
Upgrading EVO III OS takes approximately 5 minutes and requires just a few clicks; the process is almost entirely automated.
Please note that this OS distribution is customized for the EVO family hardwares. Attempting to install it on a different computer configuration may lead to unwanted results.
Before proceeding, it is highly recommended to back up your data, as the installation completely erases the EVO III hard drive. Each upgrade involves a fresh installation.
Requirements
Windows 11 is the reference platform for EVO III (standard) and EVO III Pro with full testing and benchmarking performed on version 25H2 to ensure maximum performance and reliability.
