System requirements
| Component | Minimum | Recommended |
|---|---|---|
| CPU | 1.4 GHz 64-bit | 3.1 GHz+ multi-core |
| RAM | 512 MB (Core) / 2 GB (Desktop Experience) | 16 GB+ |
| Disk | 32 GB | 100 GB+ system drive |

Step 1 — Download the ISO
- Get the official ISO from the Microsoft Evaluation Center (free registration, ~4.7 GB, 64-bit).
- Optionally verify the SHA-256 hash after download (
certutil -hashfile file.iso SHA256). - Your retail key converts the evaluation to full Standard — see the activation section below.
Step 2 — Install
- Write the ISO to a USB drive (Rufus or similar) and boot the server from it.
- Choose language and region settings.
- Enter your product key (or click I don't have a product key to add it later).
- Pick the installation type: Standard (Desktop Experience) for a full GUI, or Standard (Server Core) for a minimal command-line server.
- Accept the licence terms → Custom install → select/partition the target disk.
- Wait through file copy and restarts (20–40 minutes), then set the Administrator password.
Step 3 — Activate
Desktop Experience (GUI): Settings → System → About → Change product key → enter the 25-character key → Activate.
Server Core / evaluation converts (command line):
DISM /online /Set-Edition:ServerStandard /AcceptEula /ProductKey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX shutdown -r -t 0 slmgr /ato
