    5 min delay on cold start between login screen and bg screen

    I'm not sure when this issue was introduced into the bowels of my PC because I normally put it in sleep mode when not in use. Prior to the first time I noticed it the PC would breeze through the startup process with no discernible delays.

    Now, when I cold start it, just as the login screen closes, instead of going straight to the background screen, a black screen appears and the drive light flashes for about 4-5 minutes after which the background screen appears and all is normal. The PC will do this any time it is restarted.

    My question is, is there a way to "easily" identify the service, process, or app that is causing the delay?
    My troubleshooting skills are being diminished for these types of problems due to my neurons now approaching
    80 years of age and any help would be much appreciated.

    Try this utility to get a handle on where the time is going while you're waiting to see something on the screen: BootRacer.

    thanks Ed....I downloaded and ran the program twice .My startup stuff amounts to 12 seconds whereas something else is taking 326 seconds to get done which I have to assume is something Win10 is doing? Do you know of a similar app that can measure what Win10 is spending it's time on during startup?

    Looking around to see what's available. There's a boot log option in msconfig.exe, but I'm not 100% sure what it tells you. Let me see what I can find out ... goes off to look ... Yes, this option may very well help. See this HowToGeek article: Use Verbose Boot Messages to Troubleshoot Windows Startup Problems .
    Here's what to look for on the Boot tab in msconfig:

    The HowToGeek article explains what to do more precisely, and provides some useful information on how to find the boot log file, and then read and interpret its contents.

    PS: @Kari just ran the utility to see what's in the log file. You need to check the other box also (the one that reads "OS boot information") to get more info. Otherwise, the single box just tells you what drivers are loaded or not (not terribly informative).

    I might not need to do that now...decided to take a brute force troubleshooting approach. I use Terabyte Unlimited's Image application (Excellent tool BTW) for my backup needs so I proceeded to sequentially reload the last images until I got to one that didn't exhibit the problem.

    I was able to determine that the basic cause of the problem is an MS update that occurred within the last couple of weeks. That was late last night so today I will try to determine the exact update that causes the problem.

    Only problem with brute forcing it is I don't like to fix things without knowing exactly what I did to fix it. Besides, in this case I do need to get to the exact cause to achieve a long term fix.

    I am concerned however, that Microsoft's rather heavy handed approach to controlling MY PC is going to wind up forcing me to ultimately install the update thus recreating the issue.

    Any advice on how to handle something like this?

    I appreciate your help...thanks again.

    OK...this is what I think I know about my problem at this point.

    The boot delay is caused when update KB4074588 is installed. Uninstalling that update does not resolve the problem - once win10 gets into this situation it stays there and the only way to resolve it is to reload the pre-update disk image again. Once the boot process finally completes the PC works normally in all ways...there are no issues that I have noticed with any app.

    The boot log reveals several entries stating "BOOTLOG_NOT_LOADED \SystemRoot\System32\DRIVERS\NDProxy.sys".

    I have run chkdsk and sfc with no problems being reported.

    Here is where I'm dead in the water. Is there any way to determine what is calling for NDproxy.sys to be loaded?

    Anyone have any suggestions?

    What would be the best next move?

    My continued thanks...

    I usually use Windows Performance Toolkit to troubleshoot this kind of boot delay issues. WPT shows you what's the OS is doing during the different boot phases. If you want any help on this, here is what you have to do:

    - Download and Install windows Performance Toolkit https://docs.microsoft.com/en-us/win...ed/adk-install . Choose the package corresponding to your Windows version.
    - Record a trace using Windows Performance Recorder using these options: https://justpaste.it/1g4sx
    - Compress the resulting file
    - Share it.

    I'll analyze your trace file and give you a feedback.

    See you…

    Ed, just FYI the boot log is time stamped, (or always was ), so the procedure in this case would be to look for a process name start, then a long gap until the next item.

    You can also use it for intermittent non booting issues, as long as you can access the log file, either offline or on next successful start.- the last entry in the log is a good candidate for the fault cause.

    I've seen a few of these delays caused by network resource issues - A missing mapped drive or even USB drive

    I'd use wpt and if (if I were you) someone says the below I'd take them up on it.

    I watched his YouTube tutorial today - it was pretty good. Why not upload a trace and see how it goes?

    EDIT @zinou why not put a link to your YouTube tutorial somewhere?
