You can patch and install updates to your Windows Server virtual machines on Azure without requiring a reboot using hotpatch. This capability is available exclusively as part of Azure Automanage for Windows Server for Windows Server Azure Edition core virtual machines, and comes with the following benefits:
- Lower workload impact with less reboots
- Faster deployment of updates as the packages are smaller, install faster, and have easier patch orchestration with Azure Update Manager
- Better protection, as the hotpatch update packages are scoped to Windows security updates that install faster without rebooting
