Why Your Windows Server Product Key Matters

Before diving into recovery methods, let’s clarify why your product key is critical:

Activation: Without a valid key, Windows Server runs in “limited mode” (no critical updates or advanced features).

Reinstallation: Rebuilding or migrating servers requires the key to reactivate.

Compliance: Valid licensing avoids Microsoft compliance issues for commercial use.

How to Find Your Windows Server Product Key (4 Effective Methods)

We’ve organized these from quickest to most reliable—start with the easiest options first.

Method 1: Check Purchase Materials (5 Minutes)

Physical Copies: The key is on a COA sticker or card inside the Windows Server box (attached to DVD/USB sleeves).Online Purchases: Find the key in the retailer/Microsoft confirmation email, or log into your 微軟帳戶 > “Services & Subscriptions” > Select your license > “View Product Key.”

Method 2: Check Windows Server Settings (2 Minutes)

For already activated servers:

新聞 Win + I to open 設定.
前往 更新與安全性 > Activation (left menu).
View:
- Linked Microsoft Account: “Activated with a digital license linked to your account.”
- Local Key: Click “Change product key” to see the last 5 characters (use Magic Recovery Key for the full key).

Method 3: Use Magic Recovery Key (Most Reliable for Lost Keys)

Powershell
(Get-WmiObject -query 'select * from SoftwareLicensingService').OA3xOriginalProductKey

完整的金鑰會出現在視窗中。.

避免遺失鑰匙的最後訣竅

常見問題

1.如果我的金鑰出現 0xc004f050 錯誤，該怎麼辦？

這表示金鑰無效/過期/已使用。修復方法：檢查是否有錯字、驗證正版授權，或使用 Magic Recovery Key 取得原始金鑰。.

2.Magic Recovery Key 是否適用於不可開機的伺服器？

是的。將它安裝在一台正常運作的 PC 上，連接不可開機伺服器的硬碟機，然後透過「外部磁碟」標籤進行掃描。.

3.使用 Magic Recovery Key 是否合法？

是的 - 如果您擁有有效的 Windows Server 授權。它只能擷取已儲存的金鑰，而非盜版金鑰，並符合 Microsoft 的條款。.
