Microsoft released a patch to fix win8 manager problem

Microsoft has confirmed that a problem in Windows 8 Explorer will cause the component to crash and restart the loop, which has affected the Windows 8 Developer Preview user. .
Microsoft found that the cause of this problem seems to be related to the Metro tile, although Windows Explorer is the Windows 8 traditional desktop component. “ If your application activity tile uses a multi-image patch template, then you may run into a problem that forces Windows Explorer to restart endlessly. In the face of this problem, Windows Explorer will fall into an infinite loop of crashes and reboots. In order to solve this problem, Microsoft released a fix, the knowledge base number is KB2617028 (address). Microsoft recommends that all the problems encountered developer preview version of Windows 8 test users to download and install the Windows Update KB2617028, to fix this vulnerability.
Microsoft pointed out: "This problem is because if a request for multiple images is sent to the network at the same time, in this particular case, the notification platform crashes when trying to update the cached image file. For example, if a tile requests an image file larger than 150KB, the tile will not be rendered, which will result in a blank tile. In this case, if you send an expired HTTP header to extract the image, Explorer.exe will fall into an infinite loop of constant crashes. ”
