Recently, we encountered this problem, which caused the CPU of xps15 to overheat and the fan to run wildly After checking, many people are the same, for example: http://answers.microsoft.com/zh-hans/windows/forum/windows8_ 1-hardware/surface/82846637-0f42-4549-afc4-39e86faef77f

Recall that you have encountered similar problems before: http://hi.baidu.com/umu618/item/36d0bbd57cc21395260ae706 , immediately pick up the process explorer, check the file accessed by this file, see that it has accessed a file under the inputpersonalization folder, try to delete this folder, it seems that it has been cured in the past few hours

The specific path is: localappdata% \ \ Microsoft \ \ inputpersonalization. When you delete it, you will be prompted that the file is occupied by the windows search service. You know, to kill the process of this service SearchIndexer.exe .
