Umjesto Windows Defendera^{(Windows Defender)} , korištenje snažnog antivirusnog softverskog rješenja treće strane^{(potent third-party antivirus software solution)} za izvođenje temeljitog skeniranja na viruse najsigurnija je opcija. Na primjer, besplatna verzija Malwarebytesa^{(Malwarebytes)} izvrstan je izbor za otkrivanje i uklanjanje tvrdoglavog zlonamjernog softvera^{(detecting and removing stubborn malware)} .

10. Pokrenite SFC skeniranje ili DISM alat

Oštećena instalacija sustava Windows^(Windows) također može igrati faktor i rezultirati pogreškom ažuriranja sustava Windows^{(Windows Update)} 0x80070643. Pokretanje alata za provjeru sistemskih datoteka^{(System File Checker)} i alata DISM može pomoći u rješavanju problema sa sistemskim datotekama i poboljšati stabilnost.

Desnom tipkom miša kliknite^{(Right-click)} gumb Start i odaberite Windows PowerShell ( Administrator^(Admin) ). Zatim upišite sfc /scannow i pritisnite Enter za pokretanje alata za provjeru sistemskih datoteka^{(System File Checker)} .

Zatim unesite sljedeću naredbu i pritisnite Enter da pozovete alat DISM^(DISM) ( Deployment Image Servicing and Management ).

DISM.exe /Online /Cleanup-Image /Restorehealth

Nakon oba skeniranja upotrijebite Windows Update i provjerite ponavlja li se pogreška 0x80070643.
