Still using the W7 pro box.
I get an update of the *malicious software tool* from MS roughly monthly. On this occasion I was offered this>
2020-01 Preview of Monthly Quality Rollup for Windows 7 for x86-based Systems (KB4539601)
Installation date: 20/11/2023 16:54
Installation status: Successful
Update type: Optional
Install this update to resolve issues in Windows. For a complete listing of the issues that are included in this update, see the associated Microsoft Knowledge Base article for more information. After you install this item, you may have to restart your computer.
Appeared to install OK and required a restart.
Box re-started OK but soon lost the Internet connection. Normal re-connect failed but shut down/re-start got it going for a few more minutes.
After several cycles of this, I decided to roll the system back to before the update. Initially appeared to be OK but the download speed has dropped from 13Mb to initially 5 and now 2Mb. Upload looks normalish at 1.5Mb.
Is this likely to be a coincident line fault or?
