Microsoft claims in the release article that Windows Hotpatching provides Windows 11 users with a number of advantages. For instance, there is no need to wait for everyone to restart their systems because security upgrades are deployed instantly. IT administrators can make sure everyone has the most recent security update with this method, which also drastically shortens the vulnerability window. Furthermore, hotpatching reduces the frequency of system restarts needed by users. Consequently, there is less downtime and more output.
Other benefits include the ability to deploy smaller updates at a higher speed and control everything within the organization with Microsoft Intune and Windows Autopatch. Microsoft says that since its launch in April 2025, millions of devices have received hotpatch updates, and the company received "overwhelmingly positive feedback" about this feature.
Every month, Microsoft distributes hotpatch updates. The procedure is not flawless, though, due to stops and restarts. The business releases a baseline update every three months, which necessitates a system restart. Users can then take advantage of two months without being forced to update. Users will receive a new baseline update this month, and no-restart hotpatch upgrades are planned for August and September. However, keep in mind that some updates may be issued that still need to be restarted.
