Troubleshoot windows 7 display activation errors with a product ID that is not valid

According to official instructions and methods, it is not difficult to activate Windows 7. However, some users after the activation of Windows 7 for a period of time, the system will suddenly tell the activation status is invalid, or show activation errors, but also the product ID is not valid prompts.

In this article, you will learn the following:

The situation described at the beginning of the article is not only in Chinese users, but also in foreign users. I am now the foreign users encountered similar situation, as well as the solution to share with you.

After the user activates the Windows 7 system, if the activation status appears to be "inactive" in the system properties, you can use the "Slgmr-dli" or "SLMGR-DLV" command to view specific activation information at the command prompt first. At this point, the system will produce a "error: 0x80070422" prompt.

You are prompted by running the Slui.exe 0x2a0x80070422 command error 0x80070422: The service could not be started, either because it is disabled or because it does not have a related enabled device, as shown in Figure 1:

Figure 1:windows 7 indicates a 0x80070422 error and the service does not start.

Thus, we find the root cause of the error. This is not actually a damage to the installation disk or setup, nor is it due to the system activation failure caused by pirated Windows 7 or pirated software, but because of a problem with the Software Protection Service (Sppsvc.exe) of the system service-disabled.

Little knowledge: What is software Protection service?

In Windows 7, Software Protection services are used to detect installation and digital licenses for Windows and Windows applications. For example, the service can prevent attempts to crack Windows 7, or reject some unsigned applications.

Knowing the problem, solving the problem is simple. In system services, the Sppsvc.exe service can be opened again, as shown in Figure 2:

Figure 2: Opening the SPPSVC service

In the SPPSVC service, set its startup type to Automatic (delay start), and restart to resolve the activation issue.

Editorial Reviews: In Windows 7 system services, the SPPSVC service can be considered a relatively special one. Its main function is to prevent Windows 7 from being illegally cracked or activated, or users to install some "unsigned" software, such as some third-party cracking software. If the user encounters this kind of problem, may refer to the above method to solve.
