No, in order to utilize the hot patch feature your OS and VM must meet the prerequisites. Which states "Windows Server 2022 Datacenter: Azure Edition hosted on a supported platform, such as Azure or Azure Stack HCI with Azure benefits enabled."

2. All VMs using the supported SKUs are supported. You might find this thread helpful for how to fetch this with PowerShell. Step 5 here shows that the registry key will need to be set if you are not using one of the preconfigured SKUs:

$registryPath = "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Update\TargetingInfo\DynamicInstalled\Hotpatch.amd64"
$nameParameters = $parameters = @{
    Path = $registryPath
    Name = "Name"
    Value = "Hotpatch Enrollment Package"
    Force = $True
}

Hope this helps! Let me know if you still have questions or need further assistance.

Hi @deherman-MSFT ,
Thank you for the answer , But I was looking for keys which will already exist in the System for example similar to Azure where there is a key : HKLM\SOFTWARE\Microsoft\Windows Azure
We know it is avaliable only in case its Azure machines
Similarly I want to know if there are any registry keys for knowing Hotpatch is applicable or enabled , I would need these for my testing purpose , would be helpful if you knew anything more on these
Thank you
