Microsoft announce that hotpatching for Windows Server 2025 will be generally available as a subscription service on 1 July, 2025, costing $1.50 per CPU core per month. This new way of installing updates that doesn’t require a reboot after installation has been available for the Azure Edition of Windows Server Datacenter, but is now available to servers running outside of Azure, as long as they’re connected to Azure Arc.
