And if THAT doesn't work - like it didn't for me, there's the nuclear option.
CMD prompt (NOT powershell) +Admin priv > rd /q /s D:$RecycleBin, where D is the drive letter in question.
THAT worked.
#windows #RecycleBin #takeoffandnukeitfromorbit
(Im sure powershell would have worked but rd is an alias for rmdir or something and I didn't want to have to futz around anymore)
#takeoffandnukeitfromorbit #recyclebin #windows
