Are you sure ? I am familiar with Windows 7, 8, 8.1, 10 and Windows
Server 2003, 2008, 2012, 2016 and 2019, but Windows 2007 is a
variant of which I have never heard.<br>
Apart from that : did you delete everything <i>including</i>
C:\texlive (not just contents but directories, sub-directories and
so on) ?<br>

If by "retreat the texlive 2019" you mean "revert to texlive 2019",
that will not be the end of the world, but you <i>should</i> be
able to have both TeX Live 2019 & TeX Live 2020 installed
concurrently.<br>
