# SolidWorks Privacy Lockdown

**Author:** Atomaste Solution
**Purpose:** Block telemetry while preserving license transfer functionality

## Overview

This solution blocks all telemetry, analytics, and unnecessary communications from SolidWorks to Dassault Systèmes servers while preserving the ability to:
- Activate licenses
- Deactivate licenses
- Transfer licenses between machines

## Quick Start

### Preview Changes (Dry Run - RECOMMENDED FIRST)

```powershell
# Open PowerShell as Administrator, then run:
cd "C:\Users\antoi\SERVtomaste\Solidworks Licenses\scripts"
.\00-install-privacy-lockdown.ps1 -DryRun
```

This shows exactly what would be changed **without modifying anything**. A report is generated.

### Install (Apply All Protections)

```powershell
.\00-install-privacy-lockdown.ps1
```

### Uninstall (Remove All Protections)

```powershell
.\00-install-privacy-lockdown.ps1 -Undo
```

### Verify Status

```powershell
.\05-verify-lockdown.ps1 -Detailed
```

## Reports

Every run generates a detailed report in `scripts/reports/`:

```
scripts/reports/
  └── lockdown-report_2024-01-15_14-30-00.txt
```

### Report Contents

## What Gets Blocked

### Domains (via hosts file)

| Domain | Purpose | Status |
|--------|---------|--------|
| telemetry.solidworks.com | Telemetry | BLOCKED |
| analytics.3ds.com | Analytics | BLOCKED |
| collect.3ds.com | Data collection | BLOCKED |
| update.solidworks.com | Auto-updates | BLOCKED |
| api.3ds.com | 3DEXPERIENCE API | BLOCKED |
| swym.3ds.com | Social/community | BLOCKED |
| sentry.io | Error tracking | BLOCKED |
| o136956.ingest.sentry.io | Error tracking | BLOCKED |

### Services Disabled

- Allow outbound for: SLDWORKS.exe (main app), License wizard

### Registry Settings

- Customer Experience Improvement Program: Disabled
- Auto Check for Updates: Disabled
- Send Usage Statistics: Disabled
- 3DEXPERIENCE Integration: Disabled

## What Remains Accessible (Licensing)

| Domain | Purpose | Status |
|--------|---------|--------|
| activation.solidworks.com | License activation | ALLOWED |
| license.solidworks.com | License server | ALLOWED |
| licensing.solidworks.com | License management | ALLOWED |

## Scripts Reference

| Script | Purpose |
|--------|---------|
| `00-install-privacy-lockdown.ps1` | Master installer (runs all scripts) |
| `01-block-telemetry-hosts.ps1` | Modifies hosts file |
| `02-disable-services.ps1` | Disables Windows services |
| `03-configure-firewall.ps1` | Creates firewall rules |
| `04-disable-telemetry-registry.ps1` | Modifies registry settings |
| `05-verify-lockdown.ps1` | Verifies lockdown status |

## Individual Script Usage

Each script supports:
- `-Undo` : Reverse the changes
- `-ListOnly` : Preview changes without applying (where applicable)

### Examples

```powershell
# Preview what hosts file changes would be made
.\01-block-telemetry-hosts.ps1 -Undo  # to remove
.\01-block-telemetry-hosts.ps1        # to apply

# List services without modifying
.\02-disable-services.ps1 -ListOnly

# Preview firewall rules
.\03-configure-firewall.ps1 -ListOnly

# Check current registry settings
.\04-disable-telemetry-registry.ps1 -ListOnly
```

## Troubleshooting

### License Activation Fails

1. Verify licensing domains are accessible:
   ```powershell
   nslookup activation.solidworks.com
   nslookup license.solidworks.com
   ```

2. Temporarily remove hosts file block:
   ```powershell
   .\01-block-telemetry-hosts.ps1 -Undo
   ```

3. Complete license operation, then re-apply:
   ```powershell
   .\01-block-telemetry-hosts.ps1
   ```

### SolidWorks Won't Launch

1. Run verification:
   ```powershell
   .\05-verify-lockdown.ps1 -Detailed
   ```

2. Check if any critical service was disabled:
   ```powershell
   .\02-disable-services.ps1 -ListOnly
   ```

3. Restore all settings:
   ```powershell
   .\00-install-privacy-lockdown.ps1 -Undo
   ```

### Re-run After First SolidWorks Launch

Some registry settings only appear after SolidWorks runs for the first time. After initial launch:

```powershell
.\04-disable-telemetry-registry.ps1
```

## Backup Locations

| Component | Backup Location |
|-----------|-----------------|
| Hosts file | `C:\Windows\System32\drivers\etc\hosts.backup.solidworks` |
| Services | `%USERPROFILE%\solidworks-services-backup.json` |
| Registry | `%USERPROFILE%\solidworks-registry-backup.reg` |

## Reverting Changes

### Complete Removal

```powershell
.\00-install-privacy-lockdown.ps1 -Undo
```

### Individual Components

```powershell
.\01-block-telemetry-hosts.ps1 -Undo   # Remove hosts entries
.\02-disable-services.ps1 -Undo         # Restore services
.\03-configure-firewall.ps1 -Undo       # Remove firewall rules
.\04-disable-telemetry-registry.ps1 -Undo # Restore registry
```

## Testing License Transfer

After applying the lockdown, verify license operations work:

1. **In SolidWorks:** Help > Transfer License > Deactivate
2. Wait for confirmation
3. Help > Transfer License > Activate on new machine

If this fails, the hosts file may be blocking a required domain. Check verification script output.
