I recently had to resort to safe mode to get rid of XTU on my laptop (i5-7300HQ) as the system was freezing every time XTU initialized following a windows update.This was a mere -.085mV undervolt, and it had 6 hard restarts for the watchdog to disable it. I removed it by deleting it from C\Program Files. Now, when I attempt to bring back XTU with the latest installer, it fails with an error about a newer version already being installed. I can provide the log file on request.
