# Windows-HTML5-Viewer

## Requirements

* Windows 10 build 1909 or higher
* PADS4 Server version 2025.1 or higher

<Warning>
  PADS4 Windows HTML viewer version 1.4.0 + PADS4 version 2025.2 is required to have the "Switch User" option in the Launcher settings. Which enables easy user account switching when using Windows Kiosk mode.
</Warning>

## Overview

The Windows HTML5 Viewer offers several advantages over the legacy Windows Viewer:

* Supports sync repeat functionality
* Allows orientation changes without modifying Windows settings
* Provides a consistent experience across all HTML viewers
* Can be used as a screensaver
* Easier support for new features
* Improved performance
* Enhanced security via Kiosk mode
* Automatic updates from the PADS4 Server (no manual updates required)

> Note: This viewer shares the same limitations as other HTML viewers. Refer to the [HTML5 Viewer Known Limitations](https://support.pads4.com/en/support/solutions/articles/204000036395-known-limitations-for-html5-viewer) for more information.

## Switching to a Regular User Account

You can exit Kiosk Mode and switch to a standard Windows account in three ways:

* <u>Since PADS4 version </u>\*\*<u>2025.2</u> \*\*you can switch users with the "**Switch User**" option by entering the \*\*Viewer settings \*\*-> **Launcher settings** -> bottom right "**Switch User**"
* Use **Remote Desktop** (if configured) to log in directly using a different user account.
* Reboot the machine while holding the **Shift** key. This brings up the Windows login screen.

## Using the Viewer as a Screensaver

1. During installation, ensure Kiosk Mode is **not** enabled.
2. Open **Screensaver Settings** in Windows.
3. Select **Pads4viewer** as the screensaver.
