Podjetje Google pripravlja popravke za Android in bo posodabljalo Chrome. Treba je poudariti, da je Android treba za\u0161\u010dititi pred ranljivostmi MDS le na platformah, ki so zdru\u017eljive s x86 (za to se posebej zahvaljujemo Intelu za procesorje Atom). Proizvajalci naprav morajo izdati popravke za pametne telefone in tabli\u010dne ra\u010dunalnike na platformah Intel, Google pa je \u017ee pripravljena razdeliti potreben popravljeni kodo. Chromebooki (Chrome OS) so \u017ee za\u0161\u010diteni<\/a><\/noindex> s popravkami na nove ranljivosti, hkrati pa bo kasneje izbolj\u0161ana tudi sama operacijska sistema. Medtem Google poziva uporabnike, naj se prepri\u010dajo, da so proizvajalci naprav izdali potrebne popravke in (ali) da so ti popravki bili posredovani podjetjem Microsoft in Apple kot razvijalcema operacijskih sistemov. Za obla\u010dne platforme in podatkovne centre je podjetje Google \u017ee raz\u0161irilo<\/a><\/noindex> popravke za za\u0161\u010dito stre\u017eni\u0161kih procesorjev pred MDS.<\/p>\n

Podjetje Microsoft je prav tako izdalo popravke za operacijske sisteme in obla\u010dne platforme. Res je, da podjetje priporo\u010da, da uporabniki pridobijo popravljen mikroprogram od proizvajalcev naprav, \u010deprav je tudi ustvarilo stran<\/a><\/noindex> za samostojno prena\u0161anje popravkov.
