hey, thanks. where inside task scheduler?Enable the Auto Start option in HWiNFO, click OK to save the settings and then open Windows Task Scheduler if you see the HWiNFO task.
Understood. I killed HWInfo64, checked 'enable sensors on startup', clicked, save, and nothing changed in Task Scheduler. Latest (non-beta) versionUnder the "Task Scheduler Library"
