Hello Adam
It sounds like the laptop with the new m2 drive and Windows 11 reinstall is experiencing some issues related to Windows Defender and Intune compliance checks. Here are a few steps you can take to troubleshoot and resolve the issue:
1. Check Windows Defender settings: Ensure that Windows Defender real-time protection is enabled and functioning properly on the laptop. You can access Windows Defender settings by going to Settings > Update & Security > Windows Security.
2. Check Intune policies: Make sure that the Intune policies assigned to the laptop are correctly configured and enforced. Check if there are any specific policies related to Windows Defender settings that might be affecting the performance of the antivirus software.
3. Update Windows and drivers: Ensure that Windows 11 is fully updated with the latest updates and patches. Also, make sure that all drivers, including the drivers for the new m2 drive, are up to date.
4. Run Windows Defender offline scan: Perform an offline scan using Windows Defender to check for any malware or threats that may be affecting the performance of the laptop.
5. Re-enroll the device in Intune: If the issues persist, you may want to consider unenrolling the device from Intune and then re-enrolling it to see if that resolves the compliance check issues.
Then 4 step should resolved the issue.
