How to fix error error-bad-accessor-flags in Windows 11

Solution Steps

1. 1 Press Windows key + R, type 'regedit', and press Enter. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System. Look for a value named 'FilterAdministratorToken'. If it exists, double-click it and set its value to 0. This ensures that the administrator account is not filtered, which can cause invalid accessor flags.
2. 2 If the error occurs with a specific file, try changing its attributes. Open Command Prompt as administrator and type 'attrib -r -s -h "C:\path\to\file"' (replace with your file path). This removes read-only, system, and hidden attributes that might be causing invalid flags.
3. 3 Run a system file check to repair any corrupted system files. Open Command Prompt as administrator and type 'sfc /scannow'. This will replace any damaged files that might be causing the error.
4. 4 If the error occurs in a program, try reinstalling the program. Go to Settings > Apps > Installed apps, find the program, click the three dots, and select 'Uninstall'. Then download the latest version from the official website and install it. This resets any invalid accessor flags the program might have stored.
5. 5 If the error occurs during Windows Update, reset the Windows Update components as described in the previous error (ERROR_INVALID_ACCESS).
