If your model was originally shipped with Windows 10, then most likely a factory image of Windows 11 is not available and will probably never be available. However, in the settings app under system > recovery, you can choose to reset this PC, which will re-install Windows 11 to a clean state. Preinstalled apps and drivers that came with your computer will be removed, but most of them can be obtained automatically after the reset via Windows Update and the Microsoft Store. Everything else will have to be downloaded and installed manually from Dell's website. Note: Be sure to backup your personal files before resetting! During the reset, you can choose to keep your files, but the remove everything option will delete everything. More info about the resetting Windows 11 here.
My Dell Inspiron came with Windows 10 Pro. Windows 11 rolled out for my laptop and I did an upgrade. I want to reset my laptop to Windows 11 with preinstalled drivers and apps. I don't want to reset to factory image, which was Windows 10 and upgrade to Windows 11 again. Dell OS Recovery Tool shows only Windows 10 image is available. Is it possible to do that?
