Virtualization-Based Security (VBS) in Windows 11 provides additional protection by isolating critical parts of the operating system. While VBS improves security, it can sometimes reduce system performance, interfere with gaming, or block certain drivers. If you’re experiencing slowdowns or software compatibility issues, disabling VBS may help.

This step-by-step guide will show you how to safely disable VBS on Windows 11.

1. Check if VBS is Enabled

Before disabling VBS, you should confirm whether it’s active.

Steps:

1. Press Windows + R to open the Run dialog.

2. Type msinfo32 and press Enter.

3. In System Information, look for Virtualization-Based Security.

   • If it says Running, VBS is active.

   • If it says Not enabled, you don’t need to disable it.

1. Open Start Menu → search Windows Security → open it.

2. Go to Device Security → Core Isolation Details.

3. Toggle Memory Integrity to Off.

6. Verify VBS is Disabled

After following the steps, confirm VBS is turned off.

Final Thoughts

Disabling VBS in Windows 11 can improve system performance and compatibility with certain apps or games. However, keep in mind that turning off VBS reduces some security protections. Always weigh the benefits against potential security risks before making changes.

For the best balance, you can selectively disable Memory Integrity without turning off all VBS features.
