Error while accessing Update Settings in my VM

Question

I'm trying to set up automatic VM guest patching, but whenever I go to the "Update Settings" on my VM, I keep getting "Error occured while fetching the data for the selected machine(s), please try again." - has anyone else had this issue?

I have tried through the az cli too, but I get a different error message :

az vm update --resource-group "my-resource-group" --name "my-vm" --set osProfile.windowsConfiguration.enableAutomaticUpdates=true osProfile.windowsConfiguration.patchSettings.patchMode=AutomaticByPlatform

Couldn't find 'windowsConfiguration' in 'osProfile'. 'osProfile' does not support further indexing.

@Nathan Collins Welcome to Microsoft Q&A, thank you for posting your here!!

Could you please try to follow below process to enable automatic VM guest patching

Validate the extension isn't enabled You shouldn't see a patch setting section.
```
az vm get-instance-view --resource-group myResourceGroup --name myVM  
```
Enable the Preview for the subscription
```
  az feature register --namespace Microsoft.Compute --name InGuestAutoPatchVMPreview  
  az provider register -n Microsoft.Compute  
```
It can take up to 15 minutes, but you can check the status with az feature show --namespace Microsoft.Compute --name InGuestAutoPatchVMPreview

Update the existing VM to have it

   az vm update --resource-group myResourceGroup --name myVM --set  
   osProfile.windowsConfiguration.enableAutomaticUpdates=true  
   osProfile.windowsConfiguration.patchSettings.patchMode=AutomaticByPlatform

Now validate you got it...
```
  az vm get-instance-view --resource-group myResourceGroup --name myVM  
```
You should see: "patchSettings": {
"patchMode": "AutomaticByPlatform"
},

Hope this helps!

@Nathan Collins Thanks for sharing the update.

Please check on the following and let me know the results in the comments. If you are still seeing this issue after confirming on the following, I will further investigate on it.

Automatic VM guest patching is supported only on VMs created from images with the exact combination of publisher, offer and sku from the below supported OS images list. Custom images or any other publisher, offer, sku combinations are not supported.
Can you please check if your VM is supported.
https://learn.microsoft.com/en-us/azure/virtual-machines/automatic-vm-guest-patching#supported-os-images
There are also certain requirements for enabling automatic VM guest patching. Please ensure that you meet all of these:
https://learn.microsoft.com/en-us/azure/virtual-machines/automatic-vm-guest-patching#requirements-for-enabling-automatic-vm-guest-patching
Lastly, but most importantly, to enable automatic VM guest patching on a Windows VM, ensure that the property osProfile.windowsConfiguration.enableAutomaticUpdates is set to true in the VM template definition. This property can only be set when creating the VM.
