How to solve the Windows 7 display activation failure and ID error

In the Windows 7 system service, the sppsvc service can be regarded as a relatively special one. Its main function is to prevent Windows 7 from being illegally cracked or activated, or to install some software that is “unsigned” to the system, such as some third-party cracking software. If the user encounters such problems, they can be solved by referring to the above method.
According to official instructions and methods, it is not difficult to activate Windows 7. However, some users suddenly notice that the activation status is invalid or the activation error is displayed after the activation of Windows 7, and the product ID is invalid.
The situation described in the beginning of the article is not only in the users of China, but also in foreign users. The author now takes the similar situation encountered by foreign users and the solution to share with you.
After the user activates the Windows 7 system, if the activation status is suddenly displayed in the system properties is "not activated", you can use “slgmr -dli” or “slmgr at the "Command Prompt" The -dlv” command displays specific activation information. At this point, the system will generate a <quo; error: 0× 80070422” prompt.
You can get the prompt by running the <;slui.exe 0× 2a0×80070422” command&#&#&#&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&
Thus, we found the root cause of the error. This is actually not the installation disk or the installation program is damaged, nor is it because the pirated Windows 7 or pirated software causes the system activation to fail, but because the system service "software protection service (sppsvc.exe)" has a problem —&mdash ; is disabled.
Little Knowledge: What is Software Protection Service?
In Windows 7, Software Protection Service is a digital license for detecting installations and Windows and Windows applications. For example, the service can block attempts to crack Windows 7, or reject some unsigned applications.
Knowing the problem, solving the problem is simple. In the system service, turn the sppsvc.exe service back on.
In the sppsvc service, set its startup type to “automatic (delay start)”, and the activation problem can be solved after restarting.
