Since this issue has been reported by many people, both here and on other sites, I would assume that this is not anything that anyone is doing wrong, except MS. So I'd suggest only doing a deep clean before adding these troublesome updates, and not afterwards, at least this month. Hopefully, MS will straighten this mess out by next patch Tuesday, if not before. It seems that either the updates, and/or the deep cleaner app, needs an update. Just my opinion. Cheers and Regards
