A clean Win 11 installation removes all of that, giving you a system that feels brand new. Whether you’re upgrading from Windows 10 or reinstalling Windows 11 to fix performance issues, this full Windows 11 installation guide will walk you through everything you need from preparation to post-setup steps.

1. Understand What a Pure Windows 11 Installation Means

A pure Windows 11 installation wipes your hard drive completely before installing the operating system. Unlike a normal upgrade, a clean installation:

Removes all apps and programs

Deletes personal files

Clears drivers, registry entries, and system settings

Starts Windows from scratch for maximum stability

This is the method advanced users prefer when switching operating systems or fixing errors that updates can’t resolve.

1. Check System Requirements

Before starting your Windows 11 installation, make sure your device meets Microsoft’s minimum specs:

Required (Official)

Processor: 1GHz or faster, 64-bit, with 2+ cores

RAM: 4 GB (8 GB recommended)

Storage: 64 GB minimum (128+ GB ideal)

System firmware: UEFI with Secure Boot

TPM: Trusted Platform Module version 2.0

Graphics: DirectX 12 compatible GPU

Display: 720p or better

If your PC lacks TPM or Secure Boot, there are workarounds, but this guide focuses on the official, fully supported installation method.Visit For More Info: https://hireitexpert.co.uk/install-windows-11/

Select USB flash drive and choose a drive with at least 8 GB of space.

Let the tool create the bootable installer.

Once this is done, your USB drive becomes your Windows 11 installation tool.
