Windows Sandbox Manager

Manager and development environment for Windows Sandbox configuration files (.wsb).

Desktop application built with WinForms (.NET 8) and no third-party dependencies: only base .NET 8 libraries (System.Xml.Linq, System.IO, System.Diagnostics).

Analyzing and editing a sandbox

Features

• Sandbox management — list, create, import, rename (alias) and delete .wsb files.
• Creation wizard — generates a .wsb by answering every option, with explanatory tooltips.
• Analysis dashboard — parses the XML and displays the parameters with host path validation.
• Built-in editor — edit the XML and save your changes.
• Dark theme — custom scrollbars, title bar and tabs.
• Multi-language — 6 languages (English by default, Spanish, French, German, Portuguese, Italian).
• No external dependencies — everything is built with the base .NET 8 libraries.

---

Prerequisites

To actually run the sandboxes you create with this tool, Windows Sandbox must be enabled on your machine. The application itself runs without it, but launching a .wsb file requires the feature to be active.

Requirements

• Windows 10/11 Pro, Enterprise or Education (Home edition is not supported).
• CPU virtualization enabled in the BIOS/UEFI (Intel VT-x or AMD-V).
• SLAT (Second Level Address Translation) support.
• At least 4 GB of RAM (8 GB recommended).
• At least 1 GB of free disk space.

How to enable Windows Sandbox

Option A — Windows Features (GUI)

1. Press Win + R, type optionalfeatures and press Enter.
2. Check the box Windows Sandbox.
3. Click OK and restart your PC when prompted.

Option B — PowerShell (Administrator)

Enable-WindowsOptionalFeature -Online -FeatureName "Containers-DisposableClientVM" -All

Restart your computer after the command completes.

Option C — Command Prompt (Administrator)

dism /online /enable-feature /featurename:Containers-DisposableClientVM /all /norestart

Then restart your PC.

Verify it is enabled

Open the Start menu and search for Windows Sandbox. If the app appears, the feature is enabled. You can also run:

Get-WindowsOptionalFeature -Online -FeatureName "Containers-DisposableClientVM"

The State should be Enabled.

Troubleshooting

• The feature is missing from the list — you are likely on Windows Home; upgrade to Pro, Enterprise or Education.
• "Windows Sandbox failed to start" — make sure virtualization is enabled in the BIOS/UEFI and that Hyper-V / Virtual Machine Platform are not conflicting.
• Error 0x80070057 — run dism /online /cleanup-image /restorehealth and retry.

---

Build requirements

• .NET 8 SDK (only needed to build from source).

---

Build and run

dotnet build SandboxManager/SandboxManager.csproj -c Release
dotnet run --project SandboxManager/SandboxManager.csproj

The resulting executable is placed at SandboxManager/bin/Release/net8.0-windows/SandboxManager.exe.

Portable version (single executable)

dotnet publish SandboxManager/SandboxManager.csproj -c Release -r win-x64 ^
  --self-contained true -p:PublishSingleFile=true ^
  -p:IncludeNativeLibrariesForSelfExtract=true -p:EnableCompressionInSingleFile=true ^
  -o dist

This produces a single SandboxManager.exe that does not require .NET installed on the target PC.

Antivirus and false positives

Some antivirus programs (notably Malwarebytes) may flag the executable as MachineLearning/Anomalous.95%. It is not a virus: it is a heuristic machine-learning detection that triggers on unsigned executables.

The project already includes mitigations (complete metadata, security attributes, hardened P/Invoke, deterministic build). See SandboxManager/ANTIVIRUS.md for details and code-signing options.
