The situation described at the beginning of the article exists not only among domestic users, but also among foreign users. The author will share with you similar situations and solutions encountered by foreign users.
After activating the Windows 7 system, if the activation status in the system properties suddenly shows "Inactive", you can first use the "slgmr -dli" or "slmgr -dlv" command at the command prompt to view the specific activation information. At this point, the system will produce an "error: 0×80070422" prompt.
Run the "slui.exe 0× 2a0×80070422" command to get the prompt "Error 0× 80070422: The service cannot be started, probably because it is disabled or there is no related enabled device", as shown in figure 1:
From this, we found the root cause of the error. In fact, this is not because the installation disk or installation program is damaged, nor because the system activation is invalid due to pirated Windows 7 or pirated software, but because there is a problem with the "Software Protection Service (sppsvc.exe)" of the system service-it has been disabled.
Tips: What is software protection service?
In Windows 7, the software protection service is used to detect the installation and digital license of Windows and Windows applications. For example, the service can prevent attempts to crack Windows 7 or reject some unsigned applications.
Knowing the problem will be easy to solve. In the system service, just open the sppsvc.exe service again, as shown in Figure 2:
In the sppsvc service, set its startup type to "automatic (delayed startup)", and the activation problem can be solved after restarting.
Editor's comment:
Among the system services of Windows 7, the sppsvc service can be regarded as a special one. Its main function is to prevent Windows 7 from being illegally cracked or activated, or users from installing some "unsigned" software on the system, such as some third-party cracking software. If users encounter such problems, they can refer to the above methods to solve them.
