Good afternoon.
There is a *.bat file. How can I undo the changes he made?

@echo off
SET st2Path=c:\_Tools\SublimeText\sublime_text.exe

rem add it for all file types
rem @reg add "HKEY_CLASSES_ROOT\*\shell\Open with Sublime Text"         /t REG_SZ /v "" /d "Open with Sublime Text"   /f
rem @reg add "HKEY_CLASSES_ROOT\*\shell\Open with Sublime Text"         /t REG_EXPAND_SZ /v "Icon" /d "%st2Path%,0" /f
rem @reg add "HKEY_CLASSES_ROOT\*\shell\Open with Sublime Text\command" /t REG_SZ /v "" /d "%st2Path% \"%%1\"" /f
