Four solutions to false positives when a folder is opened in Windows 7/8

1. Disable Windows Defender

If you do not install third-party protection software, the system will enable the built-in Windows Defender by default. By default, scanning files will occupy a large amount of system resources and cause false positives when opening folders; if other protection software is installed, Windows Defender should be disabled by itself. If not, close the "Windows Defender Service" Service in the Service.

If you only want to use Windows Defender as the basic protection, you need to set a special case:

In Windows Defender, set "excluded files and folders"

Open Windows Defender and click the "Settings" tab. Corresponding exception settings are displayed on the left. You can set some files and folders as exceptions, or set a certain type or process to not check. Of course, the exception setting requires you to be harmless when you are familiar with the programs you own. If no exception is added, the scan result is only valid for this boot.

2. Restart the Desktop Window Manager.

(1) press Ctrl + Alt + Del on the keyboard to open the Task Manager, select the process tab, find the Desktop Window Manager, and end the process;

(2) at this time, the desktop will become a background-only state. In the Task Manager, select "run new task" under the "file" menu ";

(3) enter "explorer" and press Enter. The system restarts the Desktop Window Manager;

Note that using this method will close the opened folder and need to be opened again. If you have any save work, please remember to save it before proceeding.

3. Disable file preview to enable the folder window function in a separate process.

(1) find "folder options" in the control panel and switch to the "View" tab;

(2) switch to the "View" tab in the folder options, select "always show icon, never show thumbnail", and "open folder window in a separate process ". Save and exit.

4. Disable the index to increase the response speed

Right-click the target folder, select "properties", and click "Advanced" under the "General" tab. In the displayed dialog box, cancel "except for file properties, you can also index the content of this drive file.

For drive properties, on the General tab, deselect the check box "in addition to file properties, you can also index the content of this drive File" (this operation is not recommended for system disks, it takes a long time and is not necessarily successful ).

In addition, it is reported that the size limit of the thumbnail cache file is removed in Windows 8.1 2014 17025 Update (), so that if the system is suspended due to the slow generation of thumbnails, if you don't want to completely disable the thumbnail preview function, you may have to wait. The next time you open the same folder, there will be no zombie issues.
