[PD] Completely remove PD Win10

After installing pure data on windows 10 I made a mistake with the path flag under preferences -> startup.

Now I cannot get into the startup flag anymore. I only get this error:

WARNING: Font family 'DejaVu Sans Mono' not found, using default (courier) pd: can't open -nogui: can't open -nosync: can't open -path: can't open "C:/to/my/file.pd": can't open (Tcl) UNHANDLED ERROR: extra characters after close-quote while executing "pdtk_startup_dialog .gfxstub24ac940 0 "pd -nogui -nosync -path "C:/to/my/file.pd"" " ("uplevel" body line 3) invoked from within "uplevel #0 $docmds"

Every time I completely remove pd and reinstall this keeps turning back.

Where can I really, REALLY remove pure data or at least these options?

Cheers, Wilf
