If you wanted to reset the default settings for all of the users, you could run this from the SQL Command page.

Set all users forum display preferences to default.
Code
update ubbt_USER_PROFILE
set	USER_START_VIEW = "cfrm",
	USER_FAVORITES_TAB = "forums",
	USER_FAVORITES_SORT = "reply",
	USER_TOPIC_VIEW_TYPE = "flat",
	USER_TOPICS_PER_PAGE = null,
	USER_NOTIFY_ON_PM = "yes",
	USER_SHOW_AVATARS = 1,
	USER_EMAIL_WATCHLISTS = 1,
	USER_POSTS_PER_TOPIC = null,
	USER_SHOW_SIGNATURES = null,
	USER_TIME_FORMAT = null,
	USER_STYLE = 0,
	USER_TEXT_EDITOR = "standard",
	USER_HIDE_LEFT_COLUMN = 0,
	USER_HIDE_RIGHT_COLUMN = 0,
	USER_POST_LAYOUT = null,
	USER_SHOW_ALL_GRAEMLINS = 0,
	USER_SHOW_LEFT_MYSTUFF = 1

These are the default settings from a new UBB.threads 7.7.x install.

EDIT:
You could customize that SQL query to fit exactly as you'd like. If you wanted to set those defaults for just one single user, you'd add the following single line to the end of your query

Code
where USER_ID = 99999

Update "99999" to the user number you want to update. Or set it to "1" so that all future users will have those set defaults upon new account creation.

NOTE:
These are already the defaults for a fresh UBB.threads 7.7.x install.
