If you have the problem that after a restart you have to wait 1 or 2 minutes before the systems starts the AutoStart Apps/Programs, you may have success with this method.
Add/modify your registery with these values
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Serialize]
"StartupDelayInMSec"=dword:00000000
"WaitForIdleState"=dword:00000000
Most likely, you have to create these keys, since they do not exist by default.
„WaitForIdleState“ seems to be the reason for the issue. Somehow, the system will wait for an idle state before continuing to start the Apps. Depending on your system configuration, it can take a while until this happens 🙂
