The key to activate Microsoft Office is to have a valid license and complete the activation process correctly. 1. Confirm that you have purchased a Microsoft 365 subscription or permanent authorization key, or use a preinstalled version and log in to the account to activate it; 2. Open any Office app and log in to the Microsoft account you bound at the time of purchase to automatically activate it; 3. If you use a permanent authorization key, you can manually enter the key in the "Account" to complete the activation; 4. When encountering problems, check the key's legality, network connection, and version matching status, and refer to official support or contact customer service to solve it.
Activating Microsoft Office is actually not too difficult, but many people are prone to getting stuck in a certain step when operating. As long as you have the correct product key or subscription account, the whole process will basically be completed smoothly.

1. Confirm that you already have a valid license
Before starting activation, you must first confirm whether you have purchased a permanent authorization for Office or a Microsoft 365 subscription service.
If you have preinstalled Office when buying a computer, it usually comes with its own basic version (such as Office Home Student Edition), and you may also need to log in to your account to activate it yourself.
If it is a separate key, remember to save the product key provided on the email or purchase page.

Common ways include:
- Subscriptions or one-time authorization purchased on Microsoft's official website
- Authentic keys purchased by third-party platforms (note that you can identify the authenticity)
- Subscription accounts provided by the company or school
Without a license, Office can be tried for a while, but its functionality is limited and it still needs to be activated to use normally.

2. Activate Office using a Microsoft account login
In most cases, activating Office is to bind the software to your Microsoft account. This process can be performed after installation is completed.
The operation steps are as follows:
- Open any Office application, such as Word or Excel
- If the prompt "Require activation", click the "Login" button
- Enter the Microsoft account (email) and password you used to purchase Office
- After logging in successfully, Office will automatically complete activation
If you encounter problems, you can click "Change Account" or "Add Account" to log in manually. Sometimes network instability will cause activation failure. Try again or change the network environment.
3. Manually enter the product key to activate
If you are not using the subscription version and instead buy a permanently authorized product key, you can choose to enter it manually to activate it.
Specific methods:
- Open any Office app and enter the "File" menu
- Click "Account" or "Account Information"
- Find the Activate Product or Change Product Key option
- Enter the key you purchased and follow the prompts to complete the activation process
After entering the key, the system will be connected to the Internet to verify. If the verification is passed, it means that the activation is successful. If you change your computer or reinstall the system, you can also use the same key to activate it again (as long as it is still within the allowable range).
4. Common activation problems and solutions
Some users fail to activation, which may be caused by the following situations:
- The key has been used many times (especially pirated or used keys)
- Network connection is abnormal, unable to connect to Microsoft server
- The trial version is used, the trial period has passed
- The Office version does not match the key (for example, I bought Office 2021 but tried to activate Office 365)
Solutions include:
- Check whether the key source is formal
- Try changing the network environment (such as changing from a company network to a home network)
- Visit Microsoft Support Websites to query error codes
- Contact customer service for activation questions (especially if you are sure that you have bought the genuine version but cannot activate it)
Basically that's it. Activating Office is not complicated, but sometimes it will get stuck if you don’t pay attention to the details. Pay special attention to the key points of account, key and network.

The core of artificial intelligence is algorithms, especially models that can learn laws from data, such as deep learning. It trains the system through a large amount of data, allowing it to make judgments on new situations, such as face recognition and chatbots. AI is not really intelligent, but statistical methods that mimic human behavior. Common applications include voice recognition (such as Siri), image recognition (such as Alipay face-scanning payment), recommendation systems (such as TikTok and Taobao recommendations), and autonomous driving. AI's capabilities have boundaries, it can only work within the scope of training data, has no real awareness, and relies on a large number of computing resources. When looking at AI, it should be rational. It is an efficient tool but not perfect. It can be used to improve efficiency, but it also needs to be wary of its limitations.
