My Azure Windows VM is down. It started an automatic update last night and it never completed. I followed the recommended troubleshooting steps: stop, start, reapply, redeploy, etc. But nothing seems to be working. Can you please help as soon as possible?
The current VM status is "Updating" and the Health state is "Unhealthy".
Thank you

Have you made any recent changes? When was the last time the VM was running? Please also provide the VM type and location you are using.
Kindly review the activity logs and share them via private message for a better understanding of the issue.
We had tried restarting via Azure Portal and PowerShell but it didn't work. We found that solution yesterday (from other people on Reddit experiencing the same issue) and resized to v5.
It is very discouraging to see that, although this outage issue was already known by Microsoft in advance, the clients running v6 VMs were not informed in advance or after the forced update restart. Next time please inform affected users in advance or during the same day that the question is posted. Thank you

Hello @Federico de Giuli,Checking to see whether you have resolved the issue with the solution provided above, or if you need any further assistance, please let us know. We are happy to help.
Can you please share the recommended steps how to share the details via private message?
Hello @Federico de Giuli,
I’m currently checking with our team regarding this issue. In the meantime, please try the following steps:
If your VM is stuck in the Updating state, unable to restart or not able to access, try restarting it through the Azure Portal or use PowerShell to refresh its state.
If the VM is still not running after a restart, consider redeploying it from the Azure Portal.
If you're currently using a v6-series VM, try resizing it to a v4 or v5 series and then verify whether the VM is running.
Additionally, make sure that TPM (Trusted Platform Module) is disabled, as this could impact the VM's functionality and check the VM status.
Note-
If you have resized the VM size or disk configuration, try reverting to the previous size after a few hours to see if that resolves the issue.
Thank you!
Hello @Federico de Giuli,
Thank you for your patience while we investigated the issue. Our team has confirmed that it has now been fully resolved.
The root cause was identified as a firmware misconfiguration in Underhill VMs, which resulted in TPM-related file corruption and VM failures. A hotfix has been applied to prevent this issue in all newly created v6 VMs. For existing affected VMs, the recommended steps are to either disable the vTPM and restart the VM or recreate the VM.
A permanent fix was deployed on June 16, 2025, at 4:00 AM UTC. Customers have been informed and can now safely re-enable the vTPM where applicable.

have you tried updating the app and updateing windows
Sorry but your comment doesn't help much as this is not an app, it's the VM. And, as mentioned in the description, this happened during an automatic Windows update.
