This script disables the Windows Push Notification Service (WNS), including the
`WpnService` and `WpnUserService`.
WNS enables third-party developers to send notifications (toast, tile, badge, and raw updates)
from their cloud services [1].
However, this service raises privacy concerns:
However, there are privacy concerns with this service:
- It relies on connections to Microsoft cloud servers [1] [2] [3] [4] [5], potentially exposing
user data.
This delivers both local and push notifications to your device [1].
- It may bypass VPN protections and expose your device's real IP address, according to
Wikipedia (uncited) [2].

This script disables `WpnService` (Windows Push Notifications System Service) [3] and

> **Caution**: Disabling the `WpnUserService` system-wide impacts access to network settings on Windows 10,
> possibly causing issues with managing network connections [5] [6]. This issue does not occur on Windows 11 [5].
- Enhance your privacy by reducing data sent to Microsoft servers
- Improve security by limiting potential attack vectors
- Boost system performance by reducing background processes
> **Caution**:
> After running this script, you will no longer receive instant notifications from most apps.
> This may include important updates or messages.
### Technical Details
This script disables two services:
1. `WpnService` (Windows Push Notifications System Service) [3]
2. `WpnUserService` (Windows Push Notifications User Service) [4]
Disabling `WpnUserService` may cause these issues:
- **Network & Internet** in Settings:
- Windows 10: May cause issues accessing network settings [5] [6] [7].
- Windows 11: No reported issues [5].
- To reproduce (Windows 10):
1. Open **Settings**
2. Select **Network & Internet**
- **Notification Center** in taskbar:
- All Windows 11 versions:
- Prevents opening **Notification Center** [8] (known as *Action Center* on
Windows 10 [9]) .
- The **Notification Center** (known as **notification area** on Windows 10 [10])
is at the right end of the taskbar [11].
- It includes system status icons (e.g., date/time, battery, Wi-Fi) and
notifications [8] [11].
- To reproduce (Windows 11): Click the **Notification Center** icon on the taskbar.
- **Notifications & Actions** in Settings:
- Some Windows 11 versions: Unable to access **Notifications & Actions** [12] on
Settings app.
- To reproduce (Windows 11):
1. Open **Settings**
2. Select **System**
3. Select **Notifications**
Confirmed side effects per Windows version after disabling `WpnUserService` and rebooting:

| Windows 10 19H1 | 🟢 Unaffected | 🟢 Unaffected | 🟢 Unaffected |
Due to these issues, this script disables `WpnUserService` only on Windows 10 version 19H2 and earlier versions.

This function disables both system-wide and per-user services for a specified service.
Windows creates per-user services when a user signs in and deletes them upon sign-out [1].
Per-user services use the naming format <service name>_LUID, where LUID is a locally unique identifier for the user context [1].
Per-user services have system-wide counterparts with the same default startup mode [1].
These services can only be disabled using registry modifications [1].
They are hidden from the **Services** management console and not displayed in the group policy services policy editor [1].
