Microsoft makes Execution Containers generally available to fence in AI agents
MXC lets developers set what files and networks an agent may use. The rules sit outside the agent, so it cannot give itself more access.
Why it matters. that run code need clear limits. MXC gives builders one policy format across Windows, macOS and Linux.
In simple words. Microsoft released a tool that sets limits for AI helpers that run code on a computer. It decides which files and internet connections a helper can use, and the helper cannot change those rules. It is for people who build these helpers.
Skip: nothing changes for you.
