About Clean Install Windows Guide
The Clean Install Windows Guide explains how to back up data and perform a clean installation of Windows. It lists prerequisites including a genuine Windows ISO, Rufus, and a minimum 8GB USB drive, and walks through checking for file infector malware, backing up user folders from the C drive, and creating a bootable USB.
It also describes installing Windows 11 on unsupported hardware using IoT Enterprise 24H2 or newer with a PID.txt file. The guide states that clean installation formats the C drive and that making the bootable USB deletes data on the USB drive.

Clean Install Windows Guide FAQ
What do I need to clean-install Windows?
A genuine Windows ISO file, the latest version of Rufus, and a minimum 8GB USB drive.
How do I check for file infector malware?
Open PowerShell as administrator and run sc.exe start "sppsvc" > $null 2>&1; Write-Host "Error code: $LASTEXITCODE". If the output is 577 or 225, the system is most likely infected.
What if my system is infected and I do not have another clean system?
The guide suggests trying Dr.Web CureIt to remove file infector malware, but notes it may miss some infections, so using another clean system to make the bootable USB is preferred.
