Ways to prevent Windows 8 system from automatically cleaning up thumbnail information

The new user interface of the Windows 8 system and the optimization for the tablet left a deep impression on the user. In fact, Windows 8 also uses new network settings, personalization management, system login and system security options. As with previous versions of Windows, Windows 8 strictly manages user permissions to prevent users from making random changes to the system's default settings. Almost all special files, including user profiles, system32 files, and library folders, are assigned permissions by the system.

The system allows them to add and access files, modify the properties of extended files, delete folders and subfolders, and clean up junk files from folders. The Explorer folder is such a special file related to user configuration. When the space occupied by the thumbnail information reaches the limit value, the folder will automatically clean it up. This article will prevent you from automatically deleting thumbnail information by teaching you how to set the permissions of the Explorer folder, so that the thumbnail information can be saved for how long you want to save.

First, log in to the system as an administrator. We need to use the administrator's privileges to change the system settings. Win+R opens the run, enter "%userprofile%" and make sure to continue to enter AppDataLocalMicrosoftWindows in the address bar. (Note that since the path is a hidden folder, you need to check Show hidden in View - Options - View. Files, folders, and disk drives can be located at this address)

Then right-click on the Explorer folder to open the Properties window, click “Security", then click “Advanced in the Security dialog box.

Click “Add” - “Select Subject”, enter SYSTEM in the text box to get the SYSTEM permission item, click “display advanced permission", type change to “reject”, Click the advanced permission in the figure below, and click “OK” when finished.

After returning to the previous interface, click on “Apply" in the lower right corner to save the settings, then click “Active Access” and enter the just added in “Select User” SYSTEM, then click “View Active Access" to confirm that the information you just added is correct.

In case, just restart the computer and log in as an administrator. The thumbnail information will no longer be automatically cleared by the Windows 8 system. Give it a try!
