🛡️ What Causes the Core Isolation Settings Error in Microsoft Edge?

Core Isolation (aka Memory Integrity) is a Windows Security shield that isolates critical processes. In Edge, it pops up when:

• Edge's enhanced security clashes with Windows Core Isolation.
• Outdated drivers or software interfere.
• Third-party antivirus overrides settings.
• Group Policy restrictions on enterprise setups.

Spot the error? It usually says something like "Some settings are managed by your organization" or "Core Isolation must be off to change this." Time to fix it! ⭐

🔍 Quick Diagnosis: Is It Really a Core Isolation Error?

Before fixes, confirm: 1️⃣ Open Microsoft Edge > Settings > Privacy, search, and services. 2️⃣ Scroll to "Security" > Toggle options. 3️⃣ See the error? Head to Windows Security > Device security > Core isolation details.

If Memory Integrity is on, that's your culprit. Now, let's resolve it step by step.
