Activation of win8/8.1 appears "Windows detected a change in the system file is blocking

There are many problems with the activation of win8/8.1 system, the general solution is also a lot, but there are many students in the activation process I encountered a problem that Windows detected a change in the system file is preventing activation. In general, the reason for this problem is that we performed the operation of restoring the system activation mechanism, such as slmgr-ckms and Slmgr -rearm these two commands, one is to clear the kms activation settings, one is to restore the system activation state, sometimes after we execute these two commands, computer
will prompt us to restart, but we restart After that, there is still this problem, how to solve it, this is also the course that the US network wants to share with everyone today.

In general, after we see this prompt, Will directly use the computer's own restart function to restart the computer, but sometimes such a restart can not solve the problem, we all know that win8/8.1 has started a quick start , so the system defaults to restart the computer is a quick start, and there is no real shutdown and then restart, so the problem will always exist, we can open the start menu - command prompt, open, we enter shutdown -s -t 0 Enter, this is the command line to completely shut down, after the computer is turned off, we can manually start it.

Normally, this will solve the problem after restarting, but we also during the normal activation process. I will encounter a similar "shoi.slui.exe 0x2a 0× 80070422" error on the computer running microsoft windows non-core version, error: 0times; 80070422 rdquo; & ldquo; error, after encountering such a problem, we first To check if the service software protection is running normally, check the following:
