Windows 10: My Lenovo laptop has deactivated my WIN10 upgrade

several times in recent months. Troubleshooter will no longer help activate. Nothing that the chat, nor instructions to fix this problem listed under the error code has worked. Code= 0xC004F050. Thanks for any help!

Reformat upgraded win10 laptop


Is there a way to know what my license number is? Laptop is not with me at the moment so I could not check it. I believe it still has the sticker where the license is printed at. Does it retain the old license or a new one is made when I upgraded to Win10?

Second question, what would be the best step in reformatting the laptop? Is there an option in Win10 where it would reformat and come back immediately to Win10?

 

Touchpad Lenovo 720s stop working after update

After running an update, the touchpad is not working anymore. It is not even listed in Dev. Manager, just like it's gone from my laptop.

I've tried to restore Win10 - didn't work

Reinstall fresh Win10-didn't work

Install every single driver I've found on Lenovo site - didn't work.

...and also hotkeys F6 (activate/deactivate touchpad) and
F7 (airplay mode ON/OFF) don't work.

The model of laptop is

Lenovo 720S-13ARR Laptop (ideapad) - Type 81BR - Model 81BR003RUS

Thank you.

 

Win10 laptop w/laptop display (no others) labeled 2, can't change to 1


alphanumeric and Helmut, Thank you for your replies.

1. The drivers were installed when Windows 10 was installed. There was nothing on the laptop prior to installing Windows 10.
2. I don't have another display to try attaching as suggested.
3. Not sure if it's always been like this or not. I just started looking at the configuration settings a week or so ago.
4. To check hardware status, I've run a bunch of Lenovo tests and update checks. Nothing found.
5. I did the Device Manager suggestion. 2 PnP monitors listed ... clicked "Show Hidden devices" ... found 2 more PnP monitors for a total of 4 ... uninstalled all 4 ... restarted ... same situation. Results: Device Manager now only lists 2 PnP monitors total (no hidden monitors) even though the only monitor is the laptop built-in monitor, but no change on the designation of laptop monitor being number "2" monitor.

Thanks for your help and suggestions. Not sure why it is like this. Might be something like Win10 compatibility, old hardware, or similar.

I've taken enough of your time on this. I can live with it as it is. Might decide to upgrade to a new and current laptop, or just proceed as is. Anyway, your responses are greatly appreciated!
