I haven't tested Win11 - I think it should work the same as on Win10 You can also replace the file and apply the registry settings manually e.g in WinPE
Thanks Gelip. This was my mistake - just as you guessed. Although I had turned the User Account Control Settings to "Never Notify," I was not using the Administrator account. I thought that I was following the tutorial correctly, because the local account had administrator privileges. I now see that this is not the same thing - and the privileges were not high enough. I studied the posts you linked and look through the original screenshots in the tutorial again. I saw that I had to actually enable the Administrator account in Windows 10 (just like your screenshots show in Win 7). I logged out of my local user account and logged onto the Administrator account. I now made it all the way through the tutorial. I will test on the modern pc and update you with my results. Thank you!
