Just to note that the following recommendation/instruction from <a moz-do-not-send="true" href="https://tug.org/texlive/pretest.html">

Not being fully awake, I launched CMD but failed to change directory from C:\Windows\System32 to C:\TeX\Live\2021\Pre-test, and as a result, "rsync" attempted to delete everything in (and under) C:\Windows\System32. Fortunately I was operating as my normal
