Windows 10: Windows 11 Core Isolation Issue + Dell Data Vault Control Device Yellow Bang Symbol Code 48

To whom it may concern, I upgraded my Dell Desktop PC to Windows 11 from Windows 10 on 2/19/2025. Everything was working fine after the upgrade. That was until I came across a recommended action from the Device Security section of the Windows Security feature of Windows 11.Under Core Isolation, it says that my Memory Integrity is off, which may make my device vulnerable. When I try to turn it back on, it won't let me and I was prompted to resolve any incompatibilities with my device drivers. I tried to review incompatible drivers, but the list is completely empty. Here are screenshots as pro

:)

 

In settings - Is device encryption the same as core isolation?

They're not same, as they serve different purposes.

Device encryption encrypts your data, that can decrypted back while core isolation safeguards your system for malicious code/processes.

The Dell data vault is often classified as an unnecessary service which can be disabled.

See the post marked Solution at
https://www.dell.com/community/Windows-General/How-do-you-uninstall-the-Data-Vault/td-p/4775645 I would
move or rename those files instead of deleting them. That would be reversible. Deleting them would not be.

Here's additional explanation of the second part of that operation.

After you get those files moved or renamed, open Task Manager by right-clicking the Taskbar. On the Services tab right-click any data vault services and Stop them. If you stop a service you shouldn't have stopped, this also is easily undone.
