**Win11Debloat disables Windows 11's Snap Layouts and window snapping behaviors by importing specialized `.reg` files defined in [`Config/Features.json`](https://github.com/Raphire/Win11Debloat/blob/main/Config/Features.json), using the `ImportRegistryFile.ps1` helper to execute registry modifications via CLI switches like `-DisableSnapLayouts` and `-DisableWindowSnapping`.**

Win11Debloat is an open-source PowerShell utility that removes bloatware and modifies core Windows 11 behaviors. The tool exposes fine-grained control over the operating system's multi-tasking snap features through a declarative JSON configuration and a dynamic registry import pipeline.

## The Three Snap Features Controlled by Win11Debloat

Win11Debloat targets three distinct snapping capabilities, each controlled by a specific **FeatureId** defined in [`Config/Features.json`](https://github.com/Raphire/Win11Debloat/blob/main/Config/Features.json) and mapped to a dedicated `.reg` file in the `Regfiles/` directory.

### DisableWindowSnapping

The **DisableWindowSnapping** feature turns off the basic ability to snap windows to screen edges or corners using mouse drag or keyboard shortcuts. When activated via the `-DisableWindowSnapping` switch, the script imports `Regfiles/Disable_Window_Snapping.reg` to modify the underlying registry keys responsible for edge-snapping behavior.

### DisableSnapAssist

The **DisableSnapAssist** feature suppresses the suggestion pane that appears while dragging a window, which normally shows thumbnails of other open windows to fill remaining screen space. This feature uses `Regfiles/Disable_Snap_Assist.reg` and is triggered by the `-DisableSnapAssist` parameter.

### DisableSnapLayouts

The **DisableSnapLayouts** feature hides the **Snap Layouts** flyout that appears when hovering over the maximize button or dragging a window to the top of the screen. According to the source code in [`Config/Features.json`](https://github.com/Raphire/Win11Debloat/blob/main/Config/Features.json), this feature defines both an action registry file (`Disable_Snap_Layouts.reg`) and an undo file (`Enable_Snap_Layouts.reg`), allowing users to later restore the maximize-button hover menu.

## Architectural Implementation

The snap management system relies on a three-stage pipeline that separates configuration from execution.

### Feature Catalog in Config/Features.json

Each snapping feature is declared as a JSON object in **[`Config/Features.json`](https://github.com/Raphire/Win11Debloat/blob/main/Config/Features.json)** with structured metadata that drives the UI and execution logic. The `DisableSnapLayouts` entry, for example, contains:

```json
{
    "FeatureId": "DisableSnapLayouts",
    "Label": "snap layout flyout at top of screen and on maximize button",
    "Category": "Multi-tasking",
    "Action": "Hide",
    "RegistryKey": "Disable_Snap_Layouts.reg",
    "ApplyText": "Hiding snap layouts when dragging windows to top of the screen and on maximize button...",
    "UndoAction": "Show",
    "RegistryUndoKey": "Enable_Snap_Layouts.reg"
}

```

This declarative approach allows the script to reference `RegistryKey` for applying changes and `RegistryUndoKey` for reverting them without hard-coding file paths in the main logic.

### CLI Switch Handling in Win11Debloat.ps1

The entry point script **`Win11Debloat.ps1`** exposes explicit switches for each snap feature. When a user specifies `-DisableWindowSnapping`, `-DisableSnapAssist`, or `-DisableSnapLayouts`, the script adds the corresponding `FeatureId` to an internal list of selected operations. This list is then iterated to trigger the appropriate registry modifications.

### Registry Import Execution

The actual registry modification is handled by **`Scripts/Features/ImportRegistryFile.ps1`**. For each selected feature containing a `RegistryKey` property, the main script invokes:

```powershell
ImportRegistryFile "> $($feature.ApplyText)" $feature.RegistryKey

```

This helper function resolves the path against `$script:RegfilesPath` and executes `reg import` to apply the tweaks. The same pipeline handles undo operations by passing the `RegistryUndoKey` (such as `Enable_Snap_Layouts.reg`) when reverting changes.

## Command-Line Usage Examples

Disable all snapping features simultaneously using individual switches:

```powershell
.\Win11Debloat.ps1 -DisableWindowSnapping -DisableSnapAssist -DisableSnapLayouts

```

Programmatically select features by ID for batch processing:

```powershell
$features = @('DisableWindowSnapping','DisableSnapAssist','DisableSnapLayouts')
.\Win11Debloat.ps1 -FeatureIds $features

```

Manually import a specific registry file without running the full script:

```powershell
reg import "$PSScriptRoot/Regfiles/Disable_Snap_Layouts.reg"

```

Restore Snap Layouts using the built-in undo mechanism (via saved settings or GUI revert), which internally imports `Regfiles/Enable_Snap_Layouts.reg`.

## Summary

- Win11Debloat controls three distinct snapping behaviors: **DisableWindowSnapping**, **DisableSnapAssist**, and **DisableSnapLayouts**.
- Feature definitions live in **[`Config/Features.json`](https://github.com/Raphire/Win11Debloat/blob/main/Config/Features.json)**, which maps each `FeatureId` to specific `.reg` files in the `Regfiles/` directory.
- The **`ImportRegistryFile.ps1`** helper executes `reg import` commands based on JSON metadata, supporting both apply and undo operations via `RegistryKey` and `RegistryUndoKey` properties.
- Users trigger modifications through CLI switches (`-DisableSnapLayouts`) or by passing feature arrays to the script parameters.

## Frequently Asked Questions

### What registry files does Win11Debloat use to disable Snap Layouts?

Win11Debloat uses **`Regfiles/Disable_Snap_Layouts.reg`** to hide the Snap Layouts flyout, **`Regfiles/Disable_Snap_Assist.reg`** to disable the suggestion pane, and **`Regfiles/Disable_Window_Snapping.reg`** to turn off basic edge-snapping functionality. Each file contains specific registry values that modify Windows 11's multi-tasking behavior.

### Can I re-enable Snap Layouts after disabling them with Win11Debloat?

Yes. Each feature defines a `RegistryUndoKey` in [`Config/Features.json`](https://github.com/Raphire/Win11Debloat/blob/main/Config/Features.json). For Snap Layouts, the script imports **`Regfiles/Enable_Snap_Layouts.reg`** when you run the undo action through the GUI or use the saved settings revert functionality. This restores the maximize-button hover menu and top-edge dragging behavior.

### How do I disable all window snapping features at once?

Execute the main script with all three snap-related switches: `.\Win11Debloat.ps1 -DisableWindowSnapping -DisableSnapAssist -DisableSnapLayouts`. This command adds all three feature IDs to the processing queue and imports the corresponding registry files sequentially via the `ImportRegistryFile.ps1` pipeline.

### Is it safe to manually import the registry files outside the script?

Yes. The `.reg` files in the `Regfiles/` directory are standard Windows registry files. You can manually apply them using `reg import "path/to/Disable_Snap_Layouts.reg"` from an elevated PowerShell or Command Prompt window. However, using the script ensures proper path resolution and provides undo capabilities through the structured JSON configuration.
