Hi,

The ComponentBasedServicing hive is damaged beyond repair, do you have recent backups of the registry of this server?

Hi, i have a few backups from 2021 and 2022.
I cant load the SOFTWARE structure in the registry.

Try to load the SOFTWARE hive with a different name SOFTWARE-BKP or SOFTWARE-TMP. Otherwise use an offline tool like Registry Explorer Eric Zimmerman's tools

With this tool i can open it but i think its damaged.

 

[Maxstar]

Could you please send me a private message with the downloadlink for a copy of this SOFTWARE hive, maybe it can be fixed manually.

 

[Maxstar]

I've send a copy of the repaired hive, unfortunately, this one is from a year ago, is this also the same period when the problems started on this server?

Latest installed update is 10. Januar 2023 – KB5022289, so i think the problem started in Januar. But i'm not sure...

Then there are a very few options left if you don't have more recent backups.

1. Cloning this server and try to restore the backup (with the repaired SOFTWARE hive) of february 2022.
2. A repair install of this server using the Windows Server 2016 ISO.
