How to fix error error-invalid-ldt-size in Windows 11

Solution Steps

1. 1 Press Windows key + R, type 'winver' and press Enter. Check your Windows version. If you're on an older build, update Windows by going to Settings → Windows Update → Check for updates. This ensures you have the latest fixes.
2. 2 Update your drivers, especially chipset and CPU drivers. Press Windows key + X and select Device Manager. Expand 'System devices' and 'Processors'. Right-click each and select 'Update driver' → 'Search automatically'. Outdated drivers can cause memory management errors.
3. 3 Run the System File Checker. Open Command Prompt as administrator (Win+R, type 'cmd', Ctrl+Shift+Enter). Type 'sfc /scannow' and press Enter. This repairs corrupted system files that might be causing the issue.
4. 4 If the error occurs with a specific application, try running it in compatibility mode. Right-click the application's shortcut, select Properties, go to the Compatibility tab, and check 'Run this program in compatibility mode for' and select 'Windows 7' or 'Windows 10'. This can resolve issues with legacy software.
5. 5 If the error happens during boot, try performing a clean boot. Press Win+R, type 'msconfig', and press Enter. In the System Configuration window, go to the Services tab, check 'Hide all Microsoft services', then click 'Disable all'. Go to the Startup tab and click 'Open Task Manager'. Disable all startup items. Restart. This isolates if a third-party service is causing the problem.
6. 6 If the error persists, consider using System Restore. Press Win+R, type 'rstrui', and press Enter. Follow the wizard to restore your system to a point before the error started occurring.
