How to solve the problem of Windows 7 system product key

I am happy to install Windows7 and find that I need to enter the product key. Many users will encounter this situation, but what if there is no key?

Many newbies are habitually installed for the first time. I thought it must be entered. In fact, the one-step skipping of the input key during installation is also OK.

In short, the novice always loves to enter and then say ……

Suddenly, a dialog box pops up, stating that the product key you entered cannot activate Windows on this computer.

What's the matter?

Don't worry, we will analyze the root cause of the situation. From Microsoft's official literature, the four reasons why a product key might be invalid are as follows:

• You typed the wrong product key.

• The product key you typed does not match the product key assigned to Windows on your computer.

• Microsoft has identified a fake product key that you have entered.

• This product key is already in use on another computer.

First, check your product key and retype it. If you are sure that the product key is typed correctly and your product key is still invalid, you will need to purchase or otherwise obtain a new product key. To get genuine Windows, go to the Genuine Windows website and check if Windows on your computer is genuine.

Note

Look for the product key sticker on your computer (for example, on the back of your computer) or in the Windows box. Of course, in a special period, maybe you can search for it. . . This is beyond the scope of this article.

There are a lot of problems in the problem. It should be solved according to the user's own situation. If your situation is consistent with the above, then you can go home and try it.
