Windows Update Trying to download and install Windows 10 updates on Windows 11 Laptop

stevegs  - thanks for this, your suggestion worked for me. A couple of points:

• For others trying to find the Windows Update Reset Tool, there are a lot of fraudulent copies out there. This one: https://wureset.com/downloads/ and this one:  https://www.majorgeeks.com/files/details/reset_windows_update_tool.html both seem to be legit.
• Select option #2 as stevegs suggests.
• After it's done: REBOOT! (very key)
• The windows 11 troubleshooter can be accessed here: https://support.microsoft.com/en-us/windows/windows-update-troubleshooter-19bc41ca-ad72-ae67-af3c-89ce169755dd
• After you have done this, it will ask if the troubleshooter was successful. DO NOT REBOOT until you check to see if the Windows 10 updates have disappeared from the Windows Update section of the Settings menu. If they have, then go ahead and reboot. (Don't freakout when, during the reboot, the system says installing updates. I think it's actually removing them.)
• When you bring the system back up, check Windows Update again and you should see only Windows 11 updates.

TuanDung09022011 your suggestion would not work. While getting rid of the Windows.Old directory (which you can only do using this method: https://www.elevenforum.com/t/delete-windows-old-folder-in-windows-11.14587/ )  does get rid of the Windows 10 update files, it does NOT remove the update entries in the Windows Update settings menu. You will be stuck with "error" on the Windows 10 update entries forever, unless you do the bullet points I outlined above.

Thanks all - I just wanted to add more color so people didn't have to google around to put all the pieces together.

I had the same problem.  Download and install the Windows Update Reset Tool (Google it).  Run the tool and choose option 2.  When the tool is finished, close it and then run the Windows Update Troubleshooter built into Windows 11.  My updates worked normally after doing those two things.
