KB4586876 Cumulative Update .NET Framework 3.5, 4.8 Windows 10 Jan. 12 Win Update

Hi Denis:
Thank you for your detailed instructions!! This will probably take several days & I'll keep you updated.

I did steps 1 & 2. This installed more updates than I could count...something like 20-30. However, KB4586876 was not listed. Unfortunately, I had to undo several things (I now remember why I didn't update all MS products). I have Word, Excel, & Access from 2003, as well as Word & Access 2016. Updating MS products caused a "file validation" problem whenver I opened a .doc file. I fixed that (with a registry hack). However, it did something to Word 2016, where all my .doc & .docx files were opened by Word 2003 & Word 2016 wasn't an option under "Open with...". I ended up restoring everything from Macrium Reflect.

I will now start with step 3.2.

Thank you. After checking again, my settings are the same as yours. Also, As Denis pointed out, I had looked at the wrong key. I checked the registry at HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full & found it to be the same as yours.

Hi @Try3 & @Ghut:

I tried to install the runtime from Ghut post #22 (Denis: your Step 4.2) & it said that I already had the latest versions installed. I then tried to reinstall .Net Framework & went to the catalog:
PHP Code: 2021-01 Cumulative Update for .NET Framework 3.5 and 4.8 for Windows 10 Version 2004 for x64 (KB4586876)
Last Modified: 1/8/2021
but I couldn't download it. Basically, nothing happened & I got this image:



I tried Step 5.2 in post #26, but I show both 3.5 & 4.8 installed.

I guess I'll try Step 6.2 now...turning off .NET Framework 3.5 &4.8 & turning them back on. Before I do, do I need to reboot in between. I don't want to screw this up.

Thanks again to both of you!!
