        After the win8 is installed, how to solve the problem of the old flash of the Win8 system hard disk? Why is this happening, is there a better solution? Combine some experiences of using the win 8 system, and put forward some suggestions for solving the problem. I found such a problem today, I am a dual-system Win8 and Win7 networked installation, please see the tutorial of installing dual system (nt6 hard disk installation Win8/Win7 dual system) (U disk installation Win8/Win7 dual system), today's magic Found that Windows 8 does not actively run any program after the boot, the CPU has been occupying 20% ​​~ 30% look, I feel very surprised, this is definitely a problem! 4 core CPU will not let Win8 spike! After Weibo verification Some friends also reflected this problem. I think it is caused by Microsoft account login and local account differences. 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 is solved! Not the most core! Finally I saw a friend of this website share, I know why. How to solve it? Press win+I Then press Enter, enter the settings interface, select the family group on the left, and then choose to leave, exit the family group problem will be solved.
