A clean install of Windows can improve system performance and resolve issues. To begin, back up important files to a NAS, secondary PC, external storage, or cloud service. Wipe the system disk and start fresh. For installing Windows 11, options include performing a Cloud Download reinstall via the Windows Recovery Environment or using external storage with Microsoft's Media Creation Tool or an ISO. Microsoft updates installation ISOs monthly, reducing the need for additional driver installations. Download necessary drivers beforehand, focusing on graphics and chipset drivers.
To perform a clean installation, download the latest Windows 11 Disk Image (ISO) from Microsoft's website and use Rufus to write it to external storage. Rufus allows bypassing certain Windows 11 requirements, such as Secure Boot and TPM 2.0, and can facilitate creating a local account instead of using a Microsoft account. Ensure updated BIOS installations are checked if applicable. After writing the installation media, boot from it by accessing the boot menu or adjusting the UEFI setup. During installation, delete existing partitions and select empty space to proceed. Finally, install drivers post-installation.
