Microsoft will release SHA-2 critical security update to Windows 7 soon

Last year, Microsoft has issued an announcement in advance to remind users of the major changes that will be ushered in. The change is mainly for Windows 7 and Server 2008. The routine security updates released by Microsoft are mainly verified by the SHA-2 algorithm to ensure that these security updates have not been tampered with to prevent security issues. SHA-2 algorithm validation has been enabled for Windows 8 and Windows 10, but Windows 7 still uses the SHA-1 algorithm until now.

The Windows 7 Routine Security Update does not yet support SHA-2 algorithm validation, so only legacy algorithms with weaknesses can be used. Microsoft plans to provide an update specifically for SHA-2 algorithm verification on the 12th of next month. In theory, all Windows 7 users must install the update.

The routine security update provided by Microsoft for Windows 7 will verify the SHA-2 value and will refuse installation for those that cannot be successfully verified. By the time the user does not install this special high-intensity algorithm upgrade patch, any subsequent security updates from Microsoft will not be installed. The inability to install updates means that even if Windows 7 has a security vulnerability, it cannot be fixed in time, so Microsoft will inform the user in advance of this issue.

For this patch, Microsoft must also ensure that a one-time stable installation is not wrong, otherwise many Win 7 users may be exposed to risk.

The following is a specific schedule time schedule:
