I am experiencing a slowness and a bug when starting Windows 11 (23H2 build 22631.4890), it seems since installing Android Studio. At startup, after entering the login password, the screen remains much longer (1 minute more) waiting on the "Welcome" screen, then I see the taskbar displayed with the "Welcome" screen still as the background. I have to wait another 30 seconds for the normal wallpaper to appear.

enter image description here

I tried several resolutions (chkdsk, boot log ...) and finally, disabling Driver Signature Enforcement in Advanced Boot Mode. This solution worked, several times; the only problem is that it is temporary. So I tested the solutions found on several sites to try to make this modification permanent, via bcdedit

bcdedit.exe -set loadoptions DISABLE_INTEGRITY_CHECKS

bcdedit.exe -set TESTSIGNING ON

bcdedit.exe -set NOINTEGRITYCHECKS ON

Via gpedit.msc by modifying the driver installation strategy, but they do not work. I have "Secure boot" disabled in BIOS.

Are there other ways to explore? Or is it possible to hard-code and make permanent in the boot procedure the deactivation of Driver Signature Enforcement?

@Ramhound : thanks a lot for the advice about AutoRuns; it's a very powerful tool that seems to have allowed me to solve the problem: I deleted the unnecessary and unverified drivers (zntport.sys) , and updated the ones I could (FTDI); it allowed me to reactivate the integrity of the kernel, and now I no longer have any bug or slowness problems when starting!

This software also allowed me to identify and correct a problem with the explorer that crashed when I launched it from the taskbar: the problem came from an extension (Attribute Changer) ...
