SQL Server 2025 Express - service starts with delay of some hours after restart of computer

Dear Community,

we started using SQL Server 2025 Express but experienced problems with the start of service at startup.

When the computer is restarted, the service is not started. I observed this on nearly all installations and in one case it took kinda exactly 2 hours to start the service (or it was somehow delayed but without any trace in settings or windows logs).

When we start the service manually or by batch script it is starting properly at startup ...

What exactly causes this?

We only have this issue with 2025 Express and i have not yet found similar cases in the internet.

Thank you,

kind regards
