I'm looking for a straightforward way to completely disable the Windows Defender AntiMalware Service Executable (MsMpEng.exe) on Windows 11 version 25H2. I've already tried using Group Policy by enabling the "disable antivirus software" setting, but it keeps reverting back to "not set" after I restart my computer. Is there an effective method to ensure it's disabled for good?

If you want to turn off Windows Defender using Group Policy, follow this path: n
Computer Configuration
→ Administrative Templates
→ Windows Components
→ Microsoft Defender Antivirus n
Make sure you set the policy to "Turn off Windows Defender". It's important to note that sometimes, it might revert back, so you need to check if any other settings are conflicting with it.
You could try using a tool called Defender Control. It allows you to disable Defender without diving deep into the settings yourself. Just be mindful to manage your security after disabling it so your system stays safe.
Before you make any changes, ensure that you've got your data backed up. Altering BIOS or disk settings can sometimes lead to data loss, so it's always best to be cautious.
