March's Patch Tuesday for the Windows 7 brought new updates that enable support for the SHA-2 encryption algorithm.
These updates must be installed before the 16 July 2019, on the Windows 7 Service Pack 1 operating systems and on the Windows 2008 R2 Service Pack 1 operating systems before they can receive subsequent updates after that date.
You will find them through Windows Update on all Windows 7 and Windows Server 2008 devices as part of the Patch Tuesday of this month. If you do not install them, you will not be able to have any other security updates since July.
Η ενημέρωση KB4474419 εισαγάγει την υποστήριξη SHA-2 για τα Windows 7 SP1 και Windows Server 2008 R2 SP1, ενώ η KB4490628 είναι μια ενημέρωση που επιλύει ένα ζήτημα που σχετίζεται με αυτόν τον hash αλγόριθμο. Αυτό τεχνικά σημαίνει ότι το Windows Update will be ready to receive updates signed with the SHA-2 algorithm, so your device will complete downloads and installations of updates without problem.
Finally, KB4484071 is an update that specifically targets the Windows Server Update Service 3.0 service pack 2 (WSUS).
Company-based updates will be included in the next Patch Tuesday, while Windows users will be able to download and install them manually from the Microsoft Update Catalog.
