AI agents are more capable than ever, and that is exactly what makes them a potential problem. Today, most AI agents have the same permissions and file access as you do, so one hallucination can wipe out an entire folder. Today, Microsoft announced that its fix, Microsoft Execution Containers (MXC), is now generally available. MXC isolates AI agents from the rest of your system, limiting the problems caused by accidents or malicious prompts.

Agentic AI has inherent risk

An honest mistake is enough

The reality is that AI agents are “non-deterministic.” It isn’t easy to guarantee any particular outcome for a given prompt. That means that an AI agent acting on your PC doesn’t need to be malicious to cause a problem—they just need to make a mistake.
