Windows 10: Windows 10 out-of-band update KB5020435 fixes connectivity issues

Microsoft released an out-of-band update for Windows 10 on October 17th, 2022. The update addresses connectivity issues in Windows 10 version 21H2, 21H2 and 20H2.



The out-of-band update is already available. Windows administrators may run a manual check for updates using the Settings application to download and install the update on devices.

Microsoft describes the issue in the following way:

We address an issue that might affect some types of Secure Sockets Layer (SSL) and Transport Layer Security (TLS) connections. These connections might have handshake failures. For developers, the affected connections are likely to receive one or more records followed by a partial record with a size of less than 5 bytes within a single input buffer. If the connection fails, your app will receive the error, “SEC_E_ILLEGAL_MESSAGE”.
​

According to the description, SSL and TSL connections may fail on affected systems. It is unclear if all programs running on Windows are affected, or only select programs and services. Users may notice connection errors when they encounter the issue.

Installation of the update may resolve the issue. Another option that administrators have is to download the update package from Microsoft's Update Catalog website. There, it is available for all editions of Windows 10 version 20H2, 21H1 and 21H2 that Microsoft supports.

A click on the download button saves the update file to the local system. The packages have a size between 352 megabytes and 704 megabytes.

Please note that manual installation of the update requires that the latest cumulative updates or servicing stack updates are installed on the machines. Microsoft links to these on the following support pages:

• Windows 10 version 21H2
• Windows 10 version 21H2
• Windows 10 version 20H2

All Home editions of Windows 10 version 20H2 reached end of servicing in August 2022. Only Enterprise and Education editions continue to be supported. Support will run out on December 13, 2022, the last Windows Patch Day of the year 2022.

Windows update issues

+1

If your wireless router has a built in firewall maybe it's somehow set to block the ports that Windows updates use?

I'd also suggest if it works with it being directly connected then you could try resetting your router to see if this fixes the issue.

That's my 2 cents anyways. *Smile

 

Windows update issues

It works, but I still need to fix it so that way I dont have to plug computers directly to the modem to get windows update to work. It was also blocking me from installing directx.

It's good that you're not experiencing any issues. Unfortunately many folks are, a quick Google search will show the same info im offering the OP.

Heres a couple examples:

It's basically what I mentioned above, small issues here and there ,but nothing to end your day.. for the most part.

I know it's anecdotal, but for my experience 95% of the time it's perfectly fine. The issues I've run into wouldn't be enough for me to roll back , but they would be enough (had I not installed it yet) ,to avoid it for another couple weeks which is why I'm suggesting it to the OP
