The first time you need to (better) install it manually. Latest SSU and ESU: KB5031658 SSU KB5031408 Security Monthly Quality Rollup KB5029938 .NET Framework 3.5.1 KB5031001 .NET Framework 4.8 Next month (on the day the updates are released) you will try to install and configure: either “WU ESU Patcher _Standalone” or “WSUS Proxy for Windows 7”. Perhaps it will work, but many unnecessary updates will be offered => Advice: “Forget about WU, install by hand - simple, clear and reliable.”
Trying to install the enormous 121.7 MB mse definition update KB2310138 that appeared today is always failing for me with code 8050A004. Very little results for this code on google. Any one else getting this as well? I'm not sure if this is ESU related.
Hello everyone Windows Update offers to install KB4524752 and KB9477821 do I need to install them? Good day
Don't know specifics of "why not on 2nd computer?" BUT I found the page where you & FuzzleSnuz can manually download & install MSE & Windows Defender updates. Read my message #7644 on page 383. I just used it 2 days ago & works great. Good luck.
There is even a more basic way. where you take the unpacked, raw update files and place it into a specific Defender directory. This can be automated. Defender will install the files from this directory automatically. When that's done, the directory is empty, again. Note that there won't be a message of any kind.
The two I was helping are not using Defender. They are both still using MSE. Both updates can be downloaded from the MS page link I provided. Thanks.
