    Hello,

    I am really need some expert assistance here.
    I just bought a brand new gaming laptop everything is fine except for cold boot and shutdown are very slow.
    I tried google to get some insight on how to fix it but none of the basic method fix my issue.

    Tried turn on/off fast start from BIOS and system config.
    Disable all start-up programs
    Disable all non-Microsoft services

    I installed the Windows Performance Analyzer and ran a boot test CPU usage. The result shows Session Init, Winlogon Init, Explorer Init and Post Boot are 17 seconds each boot phase. I have no idea what to disable to improve the boot speed. I attached the result as a reference.

    I would like to thank you for your help in advance.

    Hi there
    These days booting via EFI is much faster than "Classical BIOS (MBR) " or legacy boot.

    It is possible to change HDD / SSD to gpt without losing data -- backup your system though with say Macrium Free first.

    If you are aleady using EFI for boot then please ignore the post -- also don't bother with "Secure boot" either.

    Cheers

    I suspect a driver signature issue as part of the problem;

    Disable temporarily the driver signature verification at boot using this command:
    bcdedit /set testsigning on

    restart your computer and check the boot time.
    Thank you Zinou.
    After I follow your instruction and disable the signature.
    Re-run the boot trace, the result improved to 41 seconds.
    Post boot seems to still slow at 22.7 seconds.

    Here is the result:

    By disabling driver signature verification, your boot time has improved. Now it takes 14.95s to display the desktop.

    Now we need to identify the driver with signature problem, because it's not recommended to disable driver signature verification to avoid loading malware when booting.

    run sigverif.exe to start File Signature verification tool.

    After you run it check the log file if there is any non-signed driver:

    Next, re-enable driver signature verification:

    bcdedit /set testsigning off

    then take another boot trace, with the following parameters:

    The size of the trace can be important, so compressed with the best compression values.

    I was only able to disable the driver signature thru advanced boot menu. I read it can only temporarily disable the driver signature. Please direct me if I need to re-enable because I do not see the re-enable option from the advanced boot menu.
    I saved the driver signature viewlog for you to review along with the boot trace.

    I didn't see the boot trace yet, but the sigverif tool has revealed one non-signed nvidia dll (nvcpl.dll).

    I suggest you completelty uninstall the NVidia drivers with DDU tool.
    Then install the drivers again => Download the drivers from the computer manufacturer's website.

    Important: before doing that create a restore point, in case there is a problem.

    Hi Zinou,

    You are the best and your analysis is incredible!!

    I follow your instruction to uninstall and re-install Nvidia Driver using DDU Tool.
    Now the viewlog is showing all signed and I ran another boot trace. The post boot init improve from 27.4 seconds to 18.9 seconds now, any chances we can improve to less than 10 seconds?
    Thank you again for your patience and help!

    Good to hear that your problem is solved

    Don't worry a lot about the post boot duration, this phase occurs after your desktop is shown. it consists of loading some services.

    If you want to gain a few seconds, disable unecessary services
    you can use autoruns tool from sysinternals for that.

    I am happy with the cold boot speed now.
    I think I am just gonna leave it like that.

    I appreciate for your patience and time to help me out on this issue!! THANK YOU!
