Microsoft has released details of a recently discovered issue in Windows 11. This is a bug in File Explorer that increases CPU usage. The problem affects all versions of Windows 11 (21H2 and 22H2) and occurs after installing update package KB5026372 released in May this year.

According to Microsoft, the problem occurs when you try to view effective access permissions for shared files and folders in the Advanced Security Settings dialog box. When you click the Effective Permissions button, you may see a message with no query results. Also, File Explorer keeps increasing CPU usage after closing the Advanced Security Options dialog.
“After installing updates dated May 9, 2023 or later, you may not be able to view the effective permissions for shared files and folders in the Advanced Security Settings dialog box.”, Microsoft said in a statement. It should be noted that the results of the query may not be displayed, but “Explorer” continues to use the processor even after the dialog box is closed.
Currently, to solve the problem, users are prompted to restart the computer or log out of the operating system and log in again. Apparently, the developers will release a patch soon to solve the increased CPU load issue due to Explorer bug in Windows 11.
