They are zeroed by a restart, so user_seeks = 0 means "not used since that instant", not "never used". last_stats_update is a different clock again: it is set by UPDATE STATISTICS / auto-update, not by usage, so a heavily used index can still carry statistics from months ago.

Drop candidates (29)

Nonclustered, not unique, not enforcing a constraint, never read. Highest write cost first — that is what the index is charging for.

Every index on the instance, including the healthy ones — the answer to "is THIS index used?" has to be here, not only the problems.
