Though I created a user account and used that w/ "success," it is unclear if I'm deleting the same things as the admin account (which failed). Creating a new user was bizzare since things started to install which I did not want.
Also with the orignal admin account, I can clean items one at a time, after that tedious cleaning if I run in mass-delete mode, another failure occurs with no hint of why. Problem reports are submitted via Windows Security & Maintenance ("check for solutions") but none are offered.
