With Windows 10 reaching end of support on 14 October 2025, it is essential to ensure your retail shop EPOS system remains secure, reliable, and fully supported. Upgrading to Windows 11 not only continues security updates but also provides enhanced system performance, stronger hardware security features such as TPM 2.0 and Secure Boot, and improved compatibility with modern applications. Before beginning the upgrade, always back up critical data and check that your drivers and software are fully compatible with Windows 11.
1. Upgrading via Windows Update
The simplest way to upgrade your retail shop EPOS system is through Windows Update. Navigate to Start > Settings > Update & Security > Windows Update, then click Check for updates.
If the upgrade is available, select Download and install.
Accept the licence terms, and the system will automatically download and install Windows 11.
Your EPOS device may restart several times during the process; ensure a stable power supply to prevent interruptions.
2. Using the Windows 11 Installation Assistant
For more control over the upgrade, the Windows 11 Installation Assistant is recommended.
Download the tool from the official Microsoft website.
It will verify your device’s compatibility, including processor, RAM, and storage requirements.
If compatible, click Accept and install and follow any restart prompts.
This method is particularly useful for businesses managing multiple retail shop EPOS systems or wishing to monitor each step of the upgrade.
3. Upgrading with Installation Media
For a clean installation or upgrading multiple devices simultaneously, installation media is the preferred approach.
Use the Windows 11 Media Creation Tool to create a USB drive or ISO file.
Insert the media into your EPOS device and run setup.exe, then follow the on-screen instructions.
This approach is especially helpful in locations with limited internet connectivity or when performing a full system reset on a retail shop EPOS system.

Ensure reliable backups: For mission-critical EPOS setups, securely back up all important data before upgrading to minimise downtime or potential data loss.
Leverage security enhancements: Windows 11 provides improved ransomware protection and hardware-based security, reducing the risk of breaches in retail environments.
