Hotpatch for Windows 11 Enterprise version 24H2 gives you the ability to apply security updates without restarting a device. This keeps your client computers up to date and secure.

Some of the benefits include:

Higher availability and fewer restarts
Faster deployment of updates because the packages are smaller, install faster, and have easier patch orchestration using Autopatch for update management.
