The term "debloat" is a bit exaggerated and you don't need to finish watching the video to see it. The "trick" just keeps the 3rd party bloatware out. It doesn't magically remove the microsoft bloatware(yes, edge is bloatware). So maybe different phrasing would've been more appropriate.
MS will "fix" this I'm sure " That’s because a Windows 11 bug comes into play that prevents the usual installation app routine. The Windows 11 installation program and Microsoft’s internet-based Out Of Box Experience are not able to process the language code for World English (en-001) and European English (en-150), explains Windows Latest. Due to the bug, the PC cannot communicate with the servers during the Windows 11 installation if one of these two regions is selected. Although an error message will be displayed during the installation process, you can simply ignore it by clicking on the “Skip” button. Adios bloatware!"
Two folders that I always delete every time I finish installing Windows 11: Edge folder (C:\Program Files (x86)\Microsoft) UWP apps folder (C:\Program Files\WindowsApps) Of course I cannot delete them in live OS, thus I use bootable WinPE USB to do it. This way I can get rid of those garbages without using script or modifying the ISO. After deleting WindowsApps folder I'll have: - No preinstalled garbages. - No Microsoft Store. Doesn't matter since I don't really need it anyway. - No Photo Viewer app including modern Paint. Doesn't matter since I have Classic Paint installer and bunch of 3rd party image viewer apps. - No modern Notepad. Doesn't matter since I'll just use classic Notepad anyway. - No Windows Terminal. Doesn't matter since I'll just use classic Command Prompt anyway.
