>>113128installing iot ltsc 2021 is the easy part, the annoying part is all the stuff you'll need to do after
e.g. installing all drivers (chipset, gpu, audio, etc.), activating with massgravel script on github, installing Microsoft Store with wsreset -i, disabling telemetry with ShutUp10 and gpedit.msc, tweaking and disabling other shit with chris titus's WinUtil, restoring Windows Photo Viewer (or installing something else like IrfanView, ImageGlass, Honeyview, nomacs, Minimal Image Viewer or whatever), installing WebpCodecSetup.exe from Google, etc.
