Computer-Use on Windows Sandbox
Posted by Impressive_Half_2819@reddit | LocalLLaMA | View on Reddit | 19 comments
Windows Sandbox support - run computer-use agents on Windows business apps without VMs or cloud costs.
Your enterprise software runs on Windows, but testing agents required expensive cloud instances. Windows Sandbox changes this - it's Microsoft's built-in lightweight virtualization sitting on every Windows 10/11 machine, ready for instant agent development.
Enterprise customers kept asking for AutoCAD automation, SAP integration, and legacy Windows software support. Traditional VM testing was slow and resource-heavy. Windows Sandbox solves this with disposable, seconds-to-boot Windows environments for safe agent testing.
What you can build: AutoCAD drawing automation, SAP workflow processing, Bloomberg terminal trading bots, manufacturing execution system integration, or any Windows-only enterprise software automation - all tested safely in disposable sandbox environments.
Free with Windows 10/11, boots in seconds, completely disposable. Perfect for development and testing before deploying to Windows cloud instances (coming later this month).

I think I'll pass.

Seems like the compression when taking a screenshot blurred the Edge logo to the point it might as well be Safari.
That's why image generators struggle with text.
Kyla_3049@reddit
Or inaccuracies when the image is converted to tokens, which the model misinterprets as it has seen MacOS desktops more than Windows desktops?

Sorry, this looks super cool, but I can't figure out what it is.
What I understand it to be: Windows has support for running an application in a protected environment, and you can automate that application (i.e., have a script controlling it). Now you say this c/ua thingy allows you to have an AI agent doing the automation?
There is so much jargon and lack of context in the blog and repo... it is hard to understand what it is all about.

Yeah so it sounds like the agent is installed on this temp instance sandbox that you can spin up and dispose of at will like a VM without as much performance overhead. This gives the agent a safe space to do whatever without having the potential of harming the host system. It then looks like it functions as a local ChatGPT Operator type service.

What models does it use?

The devs a real Redditor and they are putting in a ton of work on this. shame I cannot make it work for the life of me but I and eager for when I can.

"Run the Agent UI example: Click Run Agent UI to start the Gradio UI. If prompted to install debugpy (Python Debugger) to enable remote debugging, select 'Yes' to proceed."
"Variable workspaceFolder can not be resolved. No such folder 'cua-root'."
Every time this project shows up I give it a go. It has never worked on macOS. Not the docker method or the one click or the manual method. Last time I tried I formatted my machine fresh to make sure I wasn't introducing the errors and it didn't work and I reported the issues on GitHub.
I am so disappointed, this project looks so impressive and is so jank.
Maybe I should crack open a windows box to use with it.

hey sorry about that! you need to wait for the post-install to finish, and it prints a message to open the workspace when it's done. just added it to the readme since its easy to miss. once it finishes and the code-workspace is open it should work fine
ieatrox@reddit
the console message saying it's done? yeah I waited for that.
I'm sure it's really good when everything is set up just like the Dev boxes you demo from.
maybe using nix would help people like me?

you guys need to make a video guide, nobody just gonna instal rando repo on their pc.

Reminder!

Windows sandbox is amazing! I finally got it working to be a one-click and it opens up the vm, installs scoop, gets VCredist, vscode, python, typescript, etc. then opens VScode and asks inside the sandbox if you want to install the repository addons; which you have to manually accept.
You have to type "Turn Windows Features On/Off" in start menu or run dialogue and then turn on Hyperthreading, WSL, Windows Sandbox, and Virtualization platform in-order for Sandbox to work!

How did you automate sandbox like that?
phovos@reddit
so "all" the configuration you can do to a Sandbox is to modify its
.wsb
file that serves as the configuration file and the launcher for the VM;So how I automated it was by writing a chain of scripts that bloom off the one script call allowed in your config.wsb or whatever you call it. This involves writing your
.wsb
file such that it uses relative paths to refer to scripts in its directory. For ex:And the batch script that invokes the powershell script which I won't bother posting because you can ask DeepSeek to help you write a powershell script that does whatever you want, its the provisioning and init steps that are tricky to get timed-correctly:

Has this been tested with any local models?
