John,

Thank you for your response.  But I couldn't perform some of your instructions.

It's been 12 days since my last Windows 10 update - so according to your info I can't to an internal revert.

So I downloaded the iso file but you said:

Save the ISO on your computer      - I did
Right click then Mount                    - there is no "Mount" option when I right click the file.
Run the Setup                                  - when I extracted the files, there is a setup.exe

                   Should I run it?

Hello RichMillerMusic,

Thank you for updating me that information. Please try to run the setup but make sure to select Make sure to select Keep personal files and apps.

Important: Back up your personal data and files to an external hard drive, USB thumb drive, or cloud location (such as OneDrive) before you begin any reinstall of Windows 10 just in case something went wrong.

>"Run the Setup then Make sure to select Keep personal files and apps"

If you try to install older Windows version over newer version you DON'T get that option!

To get better result when installing older Windows version.

- Take backup all data you want to keep

- Use MCT to create bootable USB installer

- Boot from USB

- Do clean install

Well, I double-clicked setup, but I can't choose to "keep personal files and apps" because it informs me I'm trying to install an older version of Windows.

Hello RichMillerMusic,

Thank you for updating me that information. If you can't select personal files and apps, you might lose them after the installation. Did you try to Perform going back to the previous version of Windows if it will push through?

Press Start then search Recovery Options
Under Go back to the previous version of Windows
Click Get Started

Thanks, Paul.  But what do you mean by "MCT"?  And, are you suggesting booting from the USB or Installing the older version of Win-10 from the USB?
I apologize for my lack of familiarity with this process.  I've got image backups - but unfortunately haven't done one on this laptop.

In fact, the only reason I need to do anything now is that my videos have a green tint all of a sudden.  For months it's been great - but a few days ago I was in a zoom meeting and my video looked green - everyone else looked fine on my screen so it's my camera not my screen.

Any ideas what could cause that?

Thanks,

Rich

Unfortunately, it's been 11 days since the windows update.  I discovered the issue 5 days after the update, but could not get help with the issue until today when someone said to undo the update...but now it's too late.

Thanks,

~Rich

>What do you mean by "MCT"?

You can download Media Creation Tool (MCT) from here and let it create bootable USB.

https://www.microsoft.com/en-us/software-download/windows10 (Windows version v2004)

(Creating USB installer will be delete all existing data from used USB.)

Read this article how to do clean install of Windows:

https://answers.microsoft.com/en-us/windows/forum/all/clean-install-windows-10/1c426bdf-79b1-4d42-be93-17378d93e587

On John's first reply has link to download any older Windows version ISO.
From there you can download ISO matching your currently installed Windows version.

Check your Windows version: push Win key and type winver.

With that ISO you can do mount/and run setup.exe as described on previous posts. This is so called in-place repair and it will let you keep all files and installed apps 

Before any repair / clean install:

>"In fact, the only reason I need to do anything now is that my videos have a green tint all of a sudden."

This may indicate that there is something wrong with you display adapter driver and reinstall of Windows may not be necessary.

Check display adapter driver:

- Right click "Start button" (Windows logo in taskbar)

- Select device manager

- Open display adapters

- Right click your adapter and select update driver

You can also visit on display adapter manufacturer site to see if there is new driver.
