    I recommend you change your Boot event logs setup.
    You only see how long it is taking, but not what is causing it to take so much time
    How to Use Event Viewer to Find Your PCs Boot Time
    With this setup, I know that the PCI.sys driver took 38ms to load which is 12ms longer then expected, from 3 days ago.

    I haven't checked yet the zips that are 100MB+ as they are still downloading.
    I followed the link you suggested but it is the same as I already did, non more details on each drivers delay...
    It says to filter by "100" to get boot times, thats it:

    The logs from 100MB+ were corrupted when the download was finished.
