If you’re experiencing sudden high CPU utilization in Windows 11, Microsoft might know what’s causing your problems. According to the Redmond, Washington-based software giant, a nasty bug in File Explorer affects Windows 11 21H2 and 22H2.
Specifically, Microsoft says that users are prevented from viewing the “Effective Access” menu in the “Advanced Security Settings” dialog box for shared files/folders. Instead of properly responding to the user’s command, “the results of the query might not be displayed and explorer.exe might continue to use CPU after the Advanced Security settings dialog is closed.”
