Win 8 system Microsoft ID landing CPU usage high Hard disk lights have been flashing

        I found this problem today, I am a dual-system Win8 and Win7 installed on the network, install the dual system tutorial please see (nt6 hard disk installation Win8/Win7 dual system) (U disk installation Win8/Win7 dual system), today's magical discovery Windows 8 has not taken the initiative to run any program, the CPU has been occupying 20% ​​~ 30%, I feel very surprised, this is definitely a problem! 4 core CPU will not let Win8 spike! After Weibo verified, some friends also reflected this problem. I think it is caused by Microsoft account login and local account difference. Maybe after using Microsoft ID to log in, and connecting to the cloud, synchronization and other issues are high CPU usage, so create a local account, the problem solved! But this is not the core! I know that I saw the sharing of a friend of our forum, I know that it is awkward!
