I just combined @jonasLyk's technique https://secret.club/2020/04/23/directory-deletion-shell.html and one of technique from this article https://0x00sec.org/t/windows-defender-av-zero-day-vulnerability/22258 which using windows media player (service and folder).
In order to work this technique, you must to delete the 2 folders which are C:\ProgramData\Microsoft\Windows\WER\*
and C:\Program Files (x86)\Windows Media Player
with Arbitrary Files/Directories Delete bugs such as CVE-2020-1170, CVE-2020-1571, etc ...
