## 🔇 Module 4: Privacy (77 Settings)

**Description:** Windows telemetry control, OneDrive/MS Store telemetry, and bloatware removal

### What's Actually Done:
- ✅ **Windows Telemetry:** 3 modes (MSRecommended/Strict/Paranoid)
- ✅ **OneDrive Telemetry:** Feedback & sync reports disabled
- ✅ **OneDrive Sync:** Remains FUNCTIONAL (DisablePersonalSync = 0)
- ✅ **MS Store Telemetry:** AutoDownload = 3 (auto-update apps, no upgrade prompts)
- ✅ **Bloatware Removal:** 10-24+ apps removed (PolicyMethod for ENT/EDU, ClassicMethod for others)

### Operating Modes (Interactive Selection):

#### MSRecommended (Default - Fully Supported)
- AllowTelemetry = 1 (Required)
- Services NOT disabled (policies only)
- AppPrivacy: Selective (Location/Radios Force Deny, Mic/Camera user decides)
- **Best for:** Production, business environments

#### Strict (Maximum Privacy)
- AllowTelemetry = 0 (Off)
- Services: DiagTrack + dmwappushservice disabled
- AppPrivacy: Force Deny Mic/Camera/Contacts/Calendar
- **Warning:** Breaks Teams/Zoom, Windows Update error reporting
- **Best for:** High-security, standalone systems

#### Paranoid (Hardcore - NOT Recommended)

- Tasks: CEIP/AppExperience/DiskDiag disabled
- **Warning:** Breaks error analysis, support severely limited
- **Best for:** Air-gapped, extreme privacy only

### ⚠️ Windows Insider Program Compatibility

**MSRecommended mode** sets `AllowTelemetry=1` via Group Policy, which blocks Windows Insider Program enrollment. The Insider Program requires "Optional diagnostic data" (AllowTelemetry=3) for initial enrollment.

**Workaround:** Temporarily remove the `AllowTelemetry` policy before Insider enrollment:
```powershell
Remove-ItemProperty -Path "HKLM:\SOFTWARE\Policies\Microsoft\Windows\DataCollection" -Name "AllowTelemetry"
```

After enrollment, you can optionally re-apply Privacy hardening. Insider builds will continue to download even with `AllowTelemetry=1` restored.

**See:** [README Troubleshooting - Windows Insider Program Compatibility](../README.md#windows-insider-program-compatibility)

### Impact:
- ✅ No AI data collection
- ✅ No cloud processing of local data
- ✅ Copilot completely hidden from taskbar and Start menu
- ✅ Edge Copilot sidebar disabled
- ✅ Traditional app experience restored
- ✅ **Reboot required** for Recall component removal

### ⚠️ Known Limitations:
Some UI elements in Paint and Photos apps may **still be visible** but non-functional due to lack of Microsoft-provided policies:
- **Photos:** Generative Erase button, Background Blur/Remove options
- **Paint:** Some AI feature UI elements

**Why?** Microsoft does NOT provide dedicated policies to hide these UI elements. Functionality is **blocked via systemAIModels API Master Switch** (LetAppsAccessSystemAIModels = 2), but UI removal requires Microsoft to add policies in future Windows updates.

**Result:** Buttons are visible but clicking them does nothing (API access blocked).

#### 10. Windows Update Configuration (3 Simple GUI Settings)

**Aligns with Windows Settings GUI toggles** – NO forced schedules, NO auto-reboot, and only the documented policy keys needed to drive the visible switches

**Settings Applied:**

**1. Get Latest Updates Immediately (ON, managed by policy)**
- Registry: `HKLM:\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate`
- Keys:
  - `AllowOptionalContent = 1`
  - `SetAllowOptionalContent = 1`
- Effect: Enables optional/content configuration updates so the toggle "Get the latest updates as soon as they're available" is effectively ON and enforced by policy
- GUI Path: Settings > Windows Update > Advanced options > Get the latest updates as soon as they're available (will show as managed by your organization)

**2. Microsoft Update for Other Products (ON, user-toggleable)**
- Registry: `HKLM:\SOFTWARE\Microsoft\WindowsUpdate\UX\Settings`
- Key: `AllowMUUpdateService = 1`
- Effect: Get updates for Office, drivers, and other Microsoft products when updating Windows
- GUI Path: Settings > Windows Update > Advanced options > Receive updates for other Microsoft products (user can still toggle)

**3. Delivery Optimization - Downloads from Other Devices (OFF, managed by policy)**
- Registry: `HKLM:\SOFTWARE\Policies\Microsoft\Windows\DeliveryOptimization`
- Key: `DODownloadMode = 0`
- Effect: HTTP only (Microsoft servers) – no peer-to-peer, no LAN sharing
- GUI Path: Settings > Windows Update > Advanced options > Delivery Optimization > Allow downloads from other devices = OFF (managed by your organization)

**User Control & Transparency:**
- ✅ NO forced installation schedules
- ✅ NO auto-reboot policies
- ✅ Microsoft Update toggle remains user-controlled in the GUI
- ✅ Windows clearly indicates where policies manage settings ("Some settings are managed by your organization")

**Why This Approach?**
- Follows Microsoft Best Practice - matches GUI behavior
- User keeps control over installation timing
- No unexpected reboots at 3 AM
- Transparent - exactly what Windows Settings shows

#### 11. Finger Protocol Block (1 firewall rule)
- **Port:** TCP 79 outbound
- **Protection:** ClickFix malware campaign mitigation
- **Attack:** Malware uses finger.exe to retrieve commands from attacker servers
- **Impact:** Zero (Finger protocol obsolete since 1990s)

#### 12. Wireless Display Security (9 settings)

**Default Hardening (always applied, all profiles):**
- **AllowProjectionToPC = 0:** Block receiving projections (PC can't be used as display)
- **RequirePinForPairing = 2:** Always require PIN for pairing

**Optional Full Disable (user choice):**
- **AllowProjectionFromPC = 0:** Block sending projections
- **AllowMdnsAdvertisement = 0:** Don't advertise as receiver via mDNS
- **AllowMdnsDiscovery = 0:** Don't discover displays via mDNS
- **AllowProjectionFromPCOverInfrastructure = 0:** Block infrastructure projection
- **AllowProjectionToPCOverInfrastructure = 0:** Block infrastructure receiving
- **Firewall Rules:** Block Miracast ports 7236/7250 (TCP + UDP)

**Protection:**
- Prevents rogue Miracast receiver attacks (screen capture by attackers in network)
- Blocks WPS PIN brute-force on Miracast connections
- Prevents mDNS spoofing for fake display discovery
- Defense-in-depth for Miracast attack surface

**Impact:**
- Default: Presentations to TV/projector still work (sending allowed)
- Full Disable: Use HDMI/USB-C cables instead of Miracast

#### 13. Discovery Protocols Security (WS-Discovery + mDNS)

**Optional (Maximum profile - user choice):**
- **mDNS Resolver:** Disabled via registry (EnableMDNS = 0)
- **WS-Discovery Services:** FDResPub + SSDPSRV disabled
- **Firewall Blocks:** 
  - WS-Discovery ports: UDP 3702 (blocked inbound/outbound)
  - mDNS port: UDP 5353 (blocked inbound/outbound)

**Protection:**
- Prevents network mapping via WS-Discovery
- Blocks mDNS spoofing attacks (fake printers/devices)
- Reduces lateral movement attack surface
- Stops automatic device enumeration by attackers

**Impact:**
- Automatic network printer/scanner discovery stops
- Smart TV discovery via mDNS stops
- Miracast discovery via mDNS stops (even if Feature 12 allows sending)
- Manual IP configuration required for network devices

#### 14. Firewall Shields Up (Maximum profile only)

**Optional (Maximum profile):**
- **Block All Inbound:** DefaultInboundAction = Block
- **Block All Outbound:** DefaultOutboundAction = Block (with exceptions)
- Applies to Domain, Private, and Public profiles

- Prevents all IPv6 traffic including DHCPv6 Solicitation

**Protection (mitm6 attack):**
- Prevents DHCPv6 spoofing attacks
- Blocks fake DHCPv6 server → DNS takeover
- Prevents NTLM credential relay via IPv6
- Defense-in-depth (WPAD already disabled)

**Impact:**
- IPv6-only services/websites won't work
- Exchange Server may have issues if using IPv6
- Some Active Directory features may be affected
- **REBOOT REQUIRED**
