Microsoft shows Copilot upgrade with local file access and Windows-wide actions
In brief
- Microsoft's Copilot upgrade, shown October 7, adds local file access and OS-level actions.
- Hybrid Intelligence, Microsoft's concept behind the upgrade, mixes on-device and cloud AI models.
- Jacob Andreou, EVP of Copilot, demoed the agent helping with a tax-filing request.
- Microsoft says activation is opt-in, folder access is restricted and agents use separate accounts.
What the demo showed
Jacob Andreou, Microsoft's EVP of Copilot, gave the on-stage pitch, according to Crypto Briefing's report on the event. He was promoted to that role in March 2026 and runs both consumer and commercial Copilot initiatives.
The demo? Taxes.
In the video, Andreou told Microsoft's Autopilot tool he'd received an email from his accountant, then asked the agent to help get her what she'd requested. Under the Hybrid Intelligence approach, apps and tools draw on a mix of AI models (some on the device, others in the cloud) with the aim of completing tasks efficiently.
Microsoft also announced the Surface Laptop Ultra at the event. Crypto Briefing said it uses Nvidia RTX Spark silicon aimed at improved AI performance.
None of this is entirely new. In 2025, Microsoft put Copilot Actions into experimental preview for Windows Insiders, with features for local file operations and local file search.
Microsoft's stated safeguards
Microsoft's stated design is that AI activation is opt-in, folder access is restricted, and Copilot agents run under accounts separate from the user's. The company has also emphasized agent workspaces and user-controlled settings, which it says are built with privacy and security in mind.
That opt-in design cuts both ways. Crypto Briefing noted that adoption depends on users actively choosing to grant access, so the feature won't spread on its own.
The OS advantage, per Crypto Briefing
The outlet frames this as a distribution story. In its analysis, OpenAI and Anthropic generally reach users through apps and interfaces built on top of other companies' platforms, while Microsoft can build its agent directly into Windows, making deep OS integration its main differentiator.
Crypto Briefing also said the Microsoft 365 Copilot user base remains small, with a limited share of users on premium features (it didn't cite figures or a source for that view).
So will people actually hand an agent the keys to their folders? Under Microsoft's own design, they'll have to choose to, and that's where the real test sits.
Frequently asked questions
What is Microsoft's Hybrid Intelligence approach?
Hybrid Intelligence is the concept Microsoft placed its new Copilot upgrade under. Apps and tools use a mix of AI models, some running on the device and others in the cloud, with the aim of completing tasks efficiently, according to Crypto Briefing.
What safeguards has Microsoft described for Copilot's local file access?
Microsoft's stated design makes AI activation opt-in, restricts folder access, and runs Copilot agents under accounts separate from the user's. The company has also emphasized agent workspaces and user-controlled settings, which it says are designed with privacy and security in mind.
