Unyaka wonke ka-2019 waphawulwa ngumzabalazo wokuchasana nokuba semngciphekweni kwezixhobo ezahlukeneyo zeprosesa, eyona nto inxulumene nokuphunyezwa kwemiyalelo eqikelelwayo. Kutshanje Uhlobo olutsha lokuhlaselwa kwi-Intel CPU cache yiCacheOut (CVE-2020-0549). Abavelisi beprosesa, ngokukodwa i-Intel, bazama ukukhulula iipetshi ngokukhawuleza. UMicrosoft usandula ukuzisa olunye uthotho lohlaziyo olunjalo.
Zonke iinguqulelo ze Windows 10, kubandakanywa no-1909 (uHlaziyo lukaNovemba ka-2019) kunye no-1903 (uHlaziyo lukaMeyi ka-2019) kunye nolwakhiwo lwangaphambili luka-2015, lufumene iipetshi ezinohlaziyo lwe-microcode ukulungisa ubuthathaka behardware kwiiprosesa ze-Intel. Okubangela umdla, inguqulelo yokujonga kuqala yohlaziyo oluphambili olulandelayo lweWindows 10 2004, ekwabizwa ngokuba yi-20H1, ayikalufumani uhlaziyo.
Uhlaziyo lwe-microcode idilesi yobuthathaka CVE-2019-11091, CVE-2018-12126, CVE-2018-12127, kunye ne-CVE-2018-12130, kwaye izise ukuphuculwa kunye nenkxaso ephuculweyo kwezi ntsapho zilandelayo ze-CPU:
- iDenverton;
- iSandy Bridge;
- Sandy Bridge E, EP;
- Valley View;
- Whisky Lake U.
Kubalulekile ukuqaphela ukuba ezi patches zifumaneka kuphela kwi-Microsoft Update Catalogue kwaye azisasazwanga kuyo Windows 10 izixhobo ngoHlaziyo lweWindows. Abo banomdla banokuzikhuphela ngokusebenzisa la makhonkco alandelayo:
- ;
- ;

- .
Uluhlu olupheleleyo lweeprosesa ezixhaswayo kunye neenkcazo ezicacileyo zeepatches zipapashwa . UMicrosoft kunye ne-Intel bacebisa ukuba abasebenzisi bafakele uhlaziyo lwe-microcode ngokukhawuleza. Ukuqaliswa ngokutsha kwesixokelelwano kuya kufuneka ukugqibezela ukufakela.
Kwakhona ngoFebruwari 11, iphakheji elandelayo yenyanga yohlaziyo lokhuseleko kuzo zonke iinguqulelo ze-Windows 10 kulindeleke ukuba ikhululwe.Ukongeza ekupheliseni ubuthathaka kunye neempazamo zesofthiwe, mhlawumbi baya kubandakanya uhlaziyo lwe-microcode olulandelayo lwe-Intel CPUs.
