Windows 7: Boot Performance Monitoring Event 100 Errors

Boot Performance Monitoring Event 100 Errors

After some recent issues, I've been looking more carefully at the event logs. My system seems more healthy than it's been in months, but one thing I've noticed is that the Windows Diagnostics-Performance log has been showing "Error" or "Critical" for Event ID 100 as far back as I've got a retained log. The latest details are below. The log labelled this "Error." This boot was a "restart" and did not generate any log entry for events 101 to 110.

Could someone suggest why the system considers this an error and whether it's worth worrying about, and, if so, what to do about it. FWIW I've already cut back on the number of startup programs.

Many thanks, -Ron

Welcome to Seven Forums Ron. Frankly, I think everyone has those errors. I think windows is set to consider a high end machine normal, and everything else is lower on the scale. Hqave a read here for more info

Boot Times - Monitor with Event Viewer

If your boot time is consistent, then I wouldn't be concerned.

Thanks for the response. Yes, I've been monitoring those events. I have about a two year history, and for the whole period, while there have been a few boots below 100 sec, random sampling seems to scatter around 165. (Mostly reboots, since I tend to leave computer on all the time, rebooting after Windows Updates, etc.) These seem high to me, judging from others' reports, though I do realize many factors are involved. I was also curious why Windows considers these level 1 or 2 errors. Will continue to monitor while my machine settles down after recent upheaval and maybe eventually use Procmon for boot logging.

Thanks again for the interest and links, -Ron
