Windows 8 open folder on the cause of suspended animation

I have been using Windows 8 for more than a year now, but there are always some uncomfortable places. I didn’t pay much attention to the number of errors I encountered before. Now I found a problem, that is, Windows 8 is open. After some folders, the system is similar to a sudden and suspended state. After a while, it will return to normal. What is it because of this?
First of all, the author encountered this problem, the effect of opening various folders on weekdays is basically no. The image preview and video preview are always on, but the progress of the loading (green progress bar) is displayed, so there is no global stuck effect, but there are some folders that make the author open when it is a headache.

After specially observed many times, this problem will be found in the open directory when the installer. Due to personal habits, I usually save the downloaded software installation program, and these programs are not classified in detail, but directly placed in the same directory. At present, there are more than 400 files, some of which are compressed packages, and more than half of them are exe executables. Is it a problem here? Previously, when I opened this folder, there was no response to any button, and it was once collapsed twice because of this drive. The task manager can only jump out after it returns to normal, so this time open it in advance to see who is out of order.

Open the folder full of programs, and scroll to a place. After stopping, the system will be abnormally stuck. The highest ranked one is a program called MsMpEng, and the program inside the folder is only Some of the icons are displayed, and the rest are white icons. After

to be currently displayed program icons are displayed, the system returns to normal, the program also returned to the low occupancy rate.

Right click on it to open its file location in the %PROGRAMFILES%/Windows Defender folder. It can be seen that the file is a file of Windows Defender, and the corresponding service is WinDefend service. At this point, you can probably guess the cause of the suspended animation: open the folder full of applications, according to the default rules, the executable is the primary check object containing threats such as viruses, although the program is not open, but the program icon is to be accessed The program body, so also check; and too many files, only one queue check, pass (release the icon). It takes time to check itself, plus the need to check for so many programs at the same time, so the system is stuck.

After finding the cause, the solution is not difficult to think of:

1. If other protection software is installed, Windows Defender should shut itself down. If it is not closed, enter the service. Just turn off the service.
   
2. If no other protection software is installed, Windows will use Defender as a basic protection by default, so you need to set a special case.
   
   

   This problem occurs here, but it is rarely encountered in previous versions of Windows. The main reason is that Windows 8 has its own Windows Defender enabled by default. The installation is ready for use.
   

   Setting some files or folders to something other than checking is also very simple: press the start button, return to the start screen and type Defender to find the Windows Defender application, click the Settings tab, on the left There are corresponding exception settings on the side. Some files can be set, with the exception of the folder; you can also set a type or process that is not checked. Of course, the exception setting is that you need to know that the programs you have are harmless.
   
   

   After you have finished adding exceptions, open the folder again would not be the case, the need to explain again, this time in the program folder you need to be responsible for their own safe. After testing, the scan results are only valid for this launch without adding an exception. That is to say, there is no such problem after entering the folder once, but the situation will repeat after the restart. The reason is also very simple: the system can't guarantee that the file has not been modified during the restart. After the boot, the changed program may have been stored in this place, and it is natural to check it again.
