I regularly update my Elastic environment. Upgrading to version 9.4.1 was somewhat painful due to the “CPU flag” issue, but with the help of the forum, I was able to get everything back up and running. After that, I proceeded to update my agents from 9.3.4 to 9.4.1. On Linux, I still encounter the long-standing issue with the missing `.asc` file, which I have been working around for years by downloading it manually using `wget`. On Windows, the update worked without any issues on two servers. However, my Windows 11 clients are causing problems. The agent appears to update successfully but ends up being orphaned—possibly due to a missing “monitoring update” phase. Does anyone have an idea how to resolve this? ---

9.4.2 was released with some fixes related to upgrading. Might want to try that and see if that resolves things. I've also had issues with 9.4.1 agents. ---

9.4.2 does not fix this issue. At least on my client. Funny - update works on my windows servers but not on the Windows Clients here's some of the client log errors: `error encountered when detecting used flavor with top path "C:\\Program Files\\Elastic\\Agent": failed reading flavor marker file: open C:\Program Files\Elastic\Agent\.flavor: The system cannot find the file specified.` `ignoring error: failed to copy "C:\\Program Files\\Elastic\\Agent\\data\\elastic-agent-9.3.4-e1aaed\\run\\osquery-default\\osquery\\osquery.db\\LOCK" to "C:\\Program Files\\Elastic\\Agent\\data\\elastic-agent-9.4.2-dd9ee6\\run\\osquery-default\\osquery\\osquery.db\\LOCK": open C:\Program Files\Elastic\Agent\data\elastic-agent-9.3.4-e1aaed\run\osquery-default\osquery\osquery.db\LOCK: The process cannot access the file because it is being used by another process.` `ignoring error: failed to copy "C:\\Program Files\\Elastic\\Agent\\data\\elastic-agent-9.3.4-e1aaed\\run\\osquery-default\\osquery\\osquery.pid" to "C:\\Program Files\\Elastic\\Agent\\data\\elastic-agent-9.4.2-dd9ee6\\run\\osquery-default\\osquery\\osquery.pid": open C:\Program Files\Elastic\Agent\data\elastic-agent-9.3.4-e1aaed\run\osquery-default\osquery\osquery.pid: The process cannot access the file because it is being used by another process.` in time context of the update there's a "Service Control Manager" 7031 Event handling a crash of elastic agent service ---

i have collected some data. At this time the agent is in "orphaned" state. If i end both "elastic-agent.exe" the old version is started immediately. Unfortunately i am not allowed to upload the screenshot and .txt files ... ---

is this still an open issue or has it been fixed with 9.4.2 for the others?
