How to Prevent the Win8 system from automatically clearing thumbnail Information

The new user interface of the Win8 System and the optimization for the tablet are impressive. In fact, Win8 also uses new network settings, personalized management, system logon, and system security options. Similar to earlier versions of Windows, Win8 strictly manages user permissions to prevent users from arbitrarily modifying the default settings of the system. Almost all special files, including user configuration files, system32 files, and library folders, are assigned permissions by the system.

The system allows them to add and access files, modify attributes of Extended Files, delete folders and subfolders, and clear junk files from folders. The Explorer folder is a special file related to user configuration. When the space occupied by the thumbnail information reaches the limit value, the folder will be automatically cleaned up. This article will teach you how to set Explorer folder permissions to prevent them from automatically deleting thumbnail information, so that you can save the thumbnail information as long as you want.
First, to log on to the system as an administrator, we need to change the system settings with the administrator privilege. Win + R open and run, enter "% userprofile %" and OK, and continue entering \ AppData \ Local \ Microsoft \ Windows in the address bar (note that, because the path is a hidden folder, you need to check the display of hidden files, folders, and disk drivers in view-options-view to locate this address)
 
Right-click the Explorer folder to open the Properties window, click "security", and then click "advanced" in the security dialog box"
 
Click "add"-"select subject", enter SYSTEM in the text box to obtain the SYSTEM permission item, click "show advanced Permissions", and change the type to "deny ", select advanced permissions as shown in, and click "OK"
 
Return to the upper-level interface, click "application" in the lower-right corner to save the settings, click "valid access", and enter the added SYSTEM in "Select User, click "view valid access" to confirm that the information you just added is correct.
 
To prevent this, restart your computer and log on as an administrator. The thumbnail information will not be automatically cleared by Win8.
