Hi. I'm David, and I'm happy to help you.
Not all Windows Update problems are caused by antivirus software.
To be able to assist you better, please clarify the following:
Are you getting an error code in Windows Update? If yes, which one?
If it is a specific update, let me know the KB number of the update displaying the error.
If you don't get an error code, see the update history.
- (Windows 10) Press "Windows + I" and select "Update & Security > Windows Update > View update history".
- (Windows 11) Press "Windows + I" and select "Windows Update > Update history".
If you prefer, share a screenshot. Use the shortcut "Windows + Shift + S" to use the screenshot tool.
Also. What is the version and "OS Build" of your Windows?
- Press "Windows + R", type
winver, and click OK.
If you prefer, share a screenshot.
