Boot time suddenly takes longer

    Ok, perhaps I jumped the gun Although there's a rouge AV with that process name. Just FYI, Unthreat is the most CPU-hungry process in your boot sequence, although this is typical for anti-virus software.

    I don't see anomalies in the provided log, but one thing stands out.

    You've got a 15 second period that starts at around 18th second during which the CPU activity is present, but disk activity isn't. The process that consumes CPU is System (4), and its child process is smss.exe. I can't say what exactly goes on, but I assume it's either PreSMSS or SMSSInit boot phase during which drivers are loaded.

    Perhaps, you've got a bad driver update, and I'd especially look at videocard drivers that frequently cause delays during these two phases. Another indicator of hardware/driver issue is your your statement:
    Today my BIOS time is 23 secs
    Taken at the face value, it means BIOS is having troubles with initializing hardware.

    If this just happened today, System Restore to the earlier point is a good start. The next step would be to explore driver versions, especially video.

    If you're still not happy with boot time, use the clean boot technique to disable the third party software and services and see if it improves the situation. If so, restore third party stuff one by one or in small groups until you're back to the issue. That's how you'll know what the culprit is.

    I did look through my boot diagnostics in event viewer. It did show smssinint degradation (see attached) I uninstalled unthreat and my bios time was still 23 seconds and total boot 98 seconds. Trying the clean boot next...thank you again for your guidance

    I did a restore last night to a point I know was working normally. That made no change. I have just done a clean boot and bios time is 24 seconds. At this point, I'm thinking of just doing a refresh? My concern is that if I refresh and I still have the issue, will I lose the ability to trace this back to it's original source? will my log files be erased?

    What exactly do you mean by BIOS time?

    Yes, smssinit is what I was talking about. It takes 8 seconds to initialize per the event viewer log, but the gap is wider in ETL. It's still something related to drivers or hardware, but refresh may fix it, of course.

    If you refresh, you get clean Windows folder, so all logs will be gone.

    I did a refresh and everything is back to normal. I really wanted to troubleshoot the problem so I dont run into it again, but I got frustrated and took the easy way out lol here are some screenshots of my "bios time"

    Thank you very much for your time and help. People like you make this a great place to come to for assistance.

    Note that bootckcl is *very* lightweight and unless the problem is severely obvious, it's not sufficient, especially for seeing what's happening during SMSS init. I still recommend a *full* trace any time there are boot perf issues.

    I know, full traces are golden. But the auto log is good for a quick look and it's easier on the person asking the question. When you checked out my link, you could notice that even this had been too much for the TS

    Even the lightweight log gives you the process timeline, and you can learn a lot from it. Wouldn't you agree?

    Well, that explains it. Meanwhile, I think MSFT has introduced these auto logs specifically for the purpose of quick troubleshooting of the most common issues. And that's how I use it :)

    P.S. Too bad the OS is already reinstalled. I wouldn't mind seeing your analysis of the full log, but I hope I'll have another chance ;)
