If it's not turning on, you'll see errors like "Memory integrity couldn't be enabled" in Settings > Privacy & Security > Windows Security.

Common signs: ❌ Red alerts in Windows Security, Edge flagging vulnerabilities, or sluggish performance. Ready to fix it? Start with these top solutions!

Quick Checklist: Before Diving In

1️⃣ Solution 1: Update Windows and Edge for Latest Patches

Outdated software is the #1 culprit for Core Isolation not turning on. Microsoft rolls out fixes regularly.

1. Open Settings (Win + I) > Windows Update > Check for updates. Install everything! ⭐
2. In Microsoft Edge, go to edge://settings/help > Update. Restart Edge.
3. Reboot PC, then retry enabling Core Isolation in Windows Security.

Pro Tip: Enable automatic updates to stay protected. Works 70% of the time! 🎉

2️⃣ Solution 2: Enable BIOS/UEFI Settings (Secure Boot & Virtualization)

Hardware-level blocks often cause this. Enter BIOS (restart + Del/F2/F10—varies by PC).

• Secure Boot: Set to "Enabled".
• Virtualization Technology (VT-x/AMD-V): Enable.
• TPM 2.0: Enable (if available).

Save & exit. This unlocks Core Isolation for Edge's secure sandboxing.

3️⃣ Solution 3: Remove Incompatible Drivers

Old drivers clash with Memory Integrity. Here's how to hunt them down:

1. Search "Core Isolation" in Start > Click Memory integrity > Review details for incompatible drivers.
2. Open Device Manager (Win + X > Device Manager).
3. Show hidden devices > Uninstall suspects (e.g., old VPN, antivirus remnants).
4. Run Command Prompt as Admin: sfc /scannow then DISM /Online /Cleanup-Image /RestoreHealth.

Restart and toggle Core Isolation on. Edge will thank you! 👍

4️⃣ Solution 4: Reset Windows Security and Edge

If stuck, reset without losing data:

1. Settings > Apps > Installed Apps > Microsoft Edge > Advanced > Reset.
2. Powershell as Admin: Get-AppxPackage Microsoft.SecHealthUI -AllUsers | Reset-AppxPackage.
3. Re-enable Core Isolation.

5️⃣ Advanced Fix: Registry Tweak (Use with Caution)

For stubborn cases:

1. Regedit > HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceGuard.
