Hi, thanks, for whatever reason, your system is not allowing you to create an elevated (administrator) command prompt.
That is why the command is failing.
Noted only drivers for XP & Win 7 are available from Lenovo (link works although called 'Error'!)
Error
Also your system has not been verified for Win 10
Windows 10 Upgrade July 2015 / Version 1507 - Supported System List
This does not mean it won't run Win 10.. but there is no guarantee.
You can roll back to the anniversary build within 10 days of upgrading if you wish.
