新机重装系统后登录账号显示“Microsoft 365 家庭版免费试用1个月”

Question

2025年11月26日买的华为MateBook d 16笔记本，回来后自己注册激活win11和office。12月6日一键还原了系统，经重装win11系统且永久激活后，重新输入11月26日注册的office账户无法永久激活，只显示“Microsoft 365 家庭版免费试用1个月选项”。

Answer 1

Hi, I understand how confusing this can be after setting everything up.

The reason you’re seeing the “Microsoft 365 Home Free Trial” message is that the system restores removed your previous Office activation and reverted it to the default trial state.

Windows activation is separate from Office, so even though your OS is permanently activated, Office needs to be linked again to the account or product key that holds your license.

To fix this, open any Office app, go to Account, and check which account is signed in.

If it shows the trial, switch to the Microsoft account you used when you first activated Office on November 26.

If you purchased a perpetual license like Office Home & Student, you’ll need to re-enter the product key under Change License.

If you didn’t buy a license and were using the Huawei preinstalled offer, the restore reset it, so you’ll need to activate a new subscription or license.

Did you originally buy a separate Office license, or were you relying on the preinstalled trial?

Regards,
Aron

这款笔记本电脑，出厂附带预装有Office家庭版2024吗？如果有，你在12月6日一键还原系统之前，已领取激活过该Office家庭版2024吧？即已经能正常使用Office家庭版2024了吧？
