Typically, my Win 7 boot time as measured by Glary varies from 11-15 sec. One boot out of every six boots or so the boot time is 30 sec. or longer. It seems each subsequent boot to the long boot is back to 11-15 sec. Does anyone have any idea why the inconsistency? I've checked scheduled tasks, startups and auotoruns, including services, and can't find anything there. Installed is 360 Total Security, and a a dozen lightweight apps, plus Mozilla Thunderbird, Maxthon Coud browser, and Rollback Rx Professional.
