How to fix error error-unexpected-mm-create-err in Windows 11

Solution Steps

1. 1 Run Windows Memory Diagnostic. Press Windows key + R, type 'mdsched.exe' and press Enter. Choose 'Restart now and check for problems'. This will test your RAM for errors. If errors are found, your RAM may be faulty and needs replacement.
2. 2 Update your device drivers, especially chipset and graphics drivers. Press Windows key + X, select 'Device Manager'. Expand categories like 'Display adapters' and 'System devices'. Right-click each device and select 'Update driver'. Choose 'Search automatically'. Outdated drivers can cause memory management errors.
3. 3 Check for Windows updates. Press Windows key + I to open Settings, go to Windows Update, and click 'Check for updates'. Install any pending updates, as they often include fixes for memory management issues.
4. 4 Run the System File Checker and DISM. Open Terminal (Admin) and run 'sfc /scannow' first, then 'DISM /Online /Cleanup-Image /RestoreHealth'. These commands repair corrupted system files that might be causing the error.
5. 5 If you overclocked your RAM, revert to default settings. Restart your PC and enter BIOS/UEFI (usually by pressing Del or F2 during boot). Look for memory settings and set them to 'Auto' or 'Default'. Overclocking can cause instability.
