Ievads
Microsoft ir izstrādājusi PowerShell skripta paraugu, kas var palīdzēt automatizēt Windows atkopšanas vides (WinRE) atjaunināšanu izvietotajās ierīcēs, lai novērstu drošības ievainojamību CVE-2022-41099.
PowerShell skripta paraugs
Microsoft produkta komanda ir izstrādājusi PowerShell skripta paraugu, lai palīdzētu automatizēt WinRE attēlu atjaunināšanu Windows 10 un Windows 11 ierīcēs. Attiecīgajās ierīcēs izpildiet skriptu ar administratora akreditācijas datiem programmā PowerShell. Ir pieejami divi skripti — tas, kuru skriptu vajadzētu izmantot, ir atkarīgs no tā, kāda Windows versija darbojas datorā. Lūdzu, izmantojiet savam videi atbilstošo versiju.
PatchWinREScript_2004plus.ps1 (ieteicams)
Šis skripts ir paredzēts Windows 10 versijām 2004 un jaunākām versijām, ieskaitot Windows 11. Ieteicams izmantot šo skripta versiju, jo tā ir robustāka, bet izmanto līdzekļus, kas pieejami tikai Windows 10 2004 un jaunākās versijās.

Papildinformācija
Kad ierīce tika startēta ierīcē instalētajā Windows versijā, skripts veiks šādas darbības:
-
Esoša WinRE attēla (WINRE) kalns. WIM).
-
Atjauniniet WinRE attēlu ar norādīto drošo OS dinamisko atjauninājumu (saderības atjaunināšanas) pakotni, kas pieejama Windows Update katalogā. Iesakām izmantot jaunāko drošo OS dinamisko atjauninājumu, kas ir pieejams ierīcē instalētajām Windows versijām.
-
Nomāciet WinRE attēlu.
-
Ja ir bitLocker TPM aizsargātājs, atkārtoti konfigurē WinRE bitLocker pakalpojumam.
Svarīgi! Šī darbība nav vairākumā trešo pušu skriptu, lai lietotu WinRE attēla atjauninājumus.
Lietošana
Skriptam var nodot tālāk norādītos parametrus.
|
Parametrs |
Apraksts |
|---|---|
|
workDir |
<neobligātie> Norāda fragmentu vietu, kas tiek izmantota, lai ielāpus iegūtu WinRE. Ja nav norādīts, skripts izmantos ierīces noklusējuma mapi Temp. |
|
packagePath |
<nepieciešamais> Norāda ceļu un OS versijai raksturīgās un procesora arhitektūras specifiskas drošās OS dinamiskās atjaunināšanas pakotnes nosaukumu, kas jāizmanto WinRE attēla atjaunināšanai. Piemērs: |
