Hello,
Microsoft is using Certificate Pinning for Windows Update. I can't get this working properly.
Can anyone help me to paste this to the correct section? I feel this is overwritten by the bump settings of OPNSense.

You have to import the Microsoft-CA in System --> Trust --> Authorities. The Windows Update CA is not trusty on other Clients than Windows..
I think this one: https://update.microsoft.com/

Hello,
I know this is a little old topic started by me but I got the time to set this up and got it working!
You've to add this to squid bump, make sure to include the leading "." It will include the domain itself and all subdomains:
.microsoft.com.akadns.net
.windowsupdate.com
.microsoft.com
The URLs listed in Squid Wiki are to much, I reduced this. However you can do it more granular. (https://wiki.squid-cache.org/ConfigExamples/Caching/WindowsUpdates (https://wiki.squid-cache.org/ConfigExamples/Caching/WindowsUpdates))
Additionally (Thx AndyX90) you have to import the following certificates:
Microsoft Root Certificate Authority 2011 - ROOT
Microsoft Update Secure Server CA 2.1 - INTERMEDIATE
Microsoft ECC Product Root Certificate Authority 2018 - ROOT
Microsoft ECC Content Distribution Secure Server CA 2.1 - INTERMEDIATE
You have to import every certificate that throws the following error in Cache Log:
kid1| ERROR: negotiating TLS on FD 49: error:14007086:SSL routines:CONNECT_CR_CERT:certificate verify failed (1/-1/0)
Good luck ;)

I just want to say that the procedure by XeroX works! To help folks who are interested in getting Windows Update to work with Squid SSL inspection, below are the certificates that you need to import into OPNsense.
Go to OPNsense --> System --> Trust --> Authorities. Click "Add," put in whatever descriptive name you want, method should be "Import and existing Certificate Authority," then paste in the below into the "Certificate Data" box. You must include all of the text, including the part with BEGIN CERTIFICATE and END CERTIFICATE.
The first two certificates below can probably be found in your own Windows 10 installation. Type "certmgr" into the Windows search box and that should find the certificate manager. Under the folder "Trusted Root Certification Authorities," you should be able to find the first two certificates. You can export them in the "Base-64 encoded X.509" format, then open the file in Notepad, which will show you what I pasted below.
The other two certificates I found online here:
https://censys.io/certificates/6139e2df97dc93bf7e90a303f75b3968fd06c57316b45e94dcff773707cf2754 (https://censys.io/certificates/6139e2df97dc93bf7e90a303f75b3968fd06c57316b45e94dcff773707cf2754)
https://censys.io/certificates/e39f93f3b2b40fd3c41de7dfa7d0b0cb6c4d8f97cbab2bb81c178f4b5f3c7eed (https://censys.io/certificates/e39f93f3b2b40fd3c41de7dfa7d0b0cb6c4d8f97cbab2bb81c178f4b5f3c7eed)
I don't know censys.io, but the certificate appears legit as when you open it, it tells you that they are issued by the other two root authorities.
Microsoft Root Certificate Authority 2011
