A Comprehensive Guide  for Upgrading from Windows 10 to Windows 11

As we approach the end of Windows 10 support on October 14, 2025, many users are looking to upgrade to Windows 11. This guide will walk you through three official methods to upgrade your system, ensuring you're prepared for the transition. We'll cover using Windows Update, the ISO file, and the Installation Assistant, providing you with options to suit your preferences and needs.

Before You Begin let do some Essential Preparations

Check System Compatibility Use the PC Health Check app to verify if your system meets Windows 11 requirements. If you don't have it, download it from Microsoft's website.

Enable TPM 2.0 If your PC lacks TPM 2.0, you may need to enable it in UEFI settings. For AMD processors, look for TPM or AMD TPM switch. Intel users should check for Platform Trust Technology (PTT).

Ensure UEFI Mode Your system should be in UEFI mode, not legacy BIOS. Check this in System Information under "BIOS Mode."

Back Up Your Data Always create a full system backup before any major upgrade.

Update Windows 10 Ensure your current Windows 10 installation has all the latest updates.

Check Device Drivers Open Device Manager and resolve any driver issues before upgrading.

This method is the simplest but may not always offer the latest version immediately.

Download the Windows 11 ISO from Microsoft's website

Mount the ISO by double-clicking it or right-clicking and selecting "Mount"
