Before You Install
- Always verify the hash: File corruption during a 7.5 GB+ download is more common than you think. Two minutes of verification saves hours of troubleshooting.
- Understand licensing: The Professional edition is commercially licensed and requires activation. For personal use, check UnionTech’s official Home/Education edition policies.
- Create a bootable USB: Use Rufus (DD mode), Ventoy, or UnionTech’s official media tool — and back up important data first.
- Reserve disk space: Allocate at least 64 GB for the system partition; AI components and apps need extra room.
- Check your architecture: This is the amd64 build. For ARM (Kunpeng/Phytium) or LoongArch platforms, download the corresponding image.
Why “Official Untouched” Matters
A commercial desktop OS holds all of your daily work data. Images from unknown sources may:
- Carry trojans or backdoors that steal documents and credentials
- Tamper with app-store sources, poisoning every future install
- Break activation and licensing components, blocking updates
- Bundle untrusted software, creating compliance and security risks
For organizations and individuals alike, official ISO + hash verification is the only reliable path.
