Works like a charm for upgrading Windows 10 to Windows 11 in place! 1) Disconnect from the internet 2) Run the script and select option 2 3) When the process finishes run SETUP from the newly created 'fixed" ISO 4) After 1 hour (or less depending on the CPU) you are running Windows 11 and all your previous (windows 10) device drivers work! ... Tested on various systems with Intel i5, i7 processors from 2012 since 2016. Thank you !!!!
