Woke up to my computer being updated to W11 from W10, not too happy about that. I want to use massgrave to change my window to W10 LTSC.

I am not interested in Linux.

So, I went to massgrave.dev and did the script, hit 1, etc. It just say something about permanent changed to key or whatever.

So I went download W10 LTSC iso, hit setup.exe and it asked me for product key. I entered my key, say it’s not right one.

So could somebody run me step by step how to go about it? I’m not really tech savvy. I want literal step by step, telling me exactly what to do.

Thank you.

Edit: folks didn’t really provide step by step here. But I managed to do it. I activiated script via powershell and hit change edition, changed it to LTSC. And then I downloaded window 10 consumer version from massgrave and run setup.exe and done. You might have to do first step shown in first part of massgrave.dev.

So my pc went from w10 to w11 (woyhouy my approval) to w11 LTSC, to w10 IoT enterprise. I’m good now.
