I couldn't find where discussion for Microsoft Visual Studio.  I have Visual Studio. It updated itself.  I have selected not to update but to notify me, but it updated anyway.  A Trojan Horse was with the update.  Now I don't have Visual Studio, and I would like to use Visual Studio but can't due to the Trojan Horse with the updates.  Does anyone have information?  

Hello! Karen. This is Krishna Dayama.

May I know if there is any Error you get while installing Visual Studio again on your Device?

Please Presa Windows Key + R > Run box opens > type: winver

Please inform me the exact Windows OS built version.

Hope to hear from you soon. : )

Krishna Dayama.

Hi Karen,

You can check and download Visual Studio from this site

What antivirus did you use currently???

You can check if your computer get infected with second opinion scan with Sophos Hitman Pro trial. 

Check to see if your computer really got infected.

Followed by Malwarebytes.

Use Emisoft Emergencykit or Eset Online scanner as a last resort.

Terrible update. So many thinks do not work anymore.

- Google Chrome (works now after reinstall)
- Autorotation lock function disappeared
- Autorotation not working (I use a Fujitsu convertable)

- Lot of unnecessary apps and folders added to the Windows quick start menu (looks like everything installed is showing up there now (even folders),..
- maybe many more issues...

Need urgent answers from Microsoft.

What the heck happened with Windows.  There was an update  last week that wiped out all the customization on the taskbar and desktop.  It also changed the desktop image and wipeout history in MS Office.  I spent an hour re-establishing all these thing, but now the update that happened last night did it again.  What the f*** is going on with windows.  If this keeps happenning, I am going to have to buy an Apple computer.  These forced updates are horrific!!  Is there a way I can restore back to before these updates?
Also, all the bookmarks have been wipedout out in Chrome & Edge.


First I as a user, forced to pay now a not too small annual fee to Microsoft for its Win365 I am expecting proper support immediate reaction from Microsoft for this fee!

Secondly, I am not one of these computer freaks, who are constantly messing around in the settings or even registry to find "do it yourself solutions". I am simply a user, following update recommendations and instructions so please explain first with proper words for a user (what means patch you are installing???) what you want to know. I am not an IT guy!

Thirdly: If Microsoft wants to solve the issue quickly then I would expect a remote support in which I give Microsoft access to check and resolve the problems which the update created. Where do I get someone to connect to my laptop?

Further info below

  • Microsoft version and build
  • Home or Pro Pro
  • 32 bit or 64 bit 64
  • Patch you are installing Function update Windows 10, Version 2OH2
  • Reported error messages - see above. Please read my post!

The following update will not updates my home computer

2020-11 Cumulative Update for Windows 10 Version 1909 for x64-based Systems (KB4586786)

2020-11 Cumulative Update for .NET Framework 3.5 and 4.8 for Windows 10 Version 1909 for x64 (KB4580980)

The first attempt I launched at 9:00 AM and left to run  until 4:00 PM only to discover that it was 0% completed.

I reset the system, which rolled back any changes and got prompted to install again yesterday. I launched the update at 9:00 AM again and when I checked my computer in the afternoon it was 30%, so I decided to leave it until I returned home from work 13 hours later and no change, still at 30%.

Once again, reset after that second failed attempt and 24 hours of watching the circle spinning. Again I'm being prompted that the update will proceed to install when I'm not using my system.

How do I stop this endless waste of time and or get the update to actually install?
