Hi, after the latest Windows 11 update, my laptop takes a very long time to start up and reach the desktop. Before the update, it was much faster. I have already tried disabling startup apps, running disk cleanup, and updating drivers, but the issue remains. Is there a specific setting or fix I should try to speed up the startup again.

    I have same problem in last 4 weeeks:

    Windows 11 Pro 24H2 26100.4946

    interface: 1000.26100.197.0

    last update - Windows 11 Version 24H2 for X64 processor systems (KB5063878) (26100.4946)

    I tried everything what is on internet + Ai said with startup/boot analyze.

    My Win before this problem started in 5 second, now it took 1-2 minutes.

    Open the Settings App, then go to Windows updates - Update History, what is the KB number of the most recent Updates that were installed.
