Microsoft Defender Offline scan: BitLocker recovery prompt and missing scan results on Windows11 Pro

Your Offline scan now reaches its progress screen after unlocking C:, but you still lack evidence that it completed. Event 2030 confirms preparation for the next reboot; it is not a completion event. A 1000/1002 pair labelled scheduled Quick Scan describes that scan’s start and cancellation, not proof that Offline was converted into a Quick Scan.

Check reagentc /info from an administrator terminal to confirm WinRE remains enabled, then update Defender’s security intelligence. Record the exact start and return times of one Offline run and compare Protection history with the Defender Operational log. Correlate ordinary scan events by Scan ID; event 1001 denotes completion for that recorded scan.

BitLocker and WinRE are relevant prerequisites, but these logs cannot establish a TPM, Secure Boot or BIOS defect. Keep their settings unchanged and provide the timeline and exported logs privately through your existing support case before considering another reinstall.
