Let's reinstall a system, not to mention that the system is completely normal. It's just that some modules in the system may only be used by CPC, but not at other times, so you haven't encountered it. It should be that there is a problem with the compatibility between the system and CPC. This kind of attempt can only be made over and over again by yourself. wen7 is really prone to some strange problems, and xp is the best system. After all, the government clients are relatively low.
Someone has solved this problem by reinstalling the system.
