Mouse and keyboard input not working after windows 10 upgrade from windows 7.

My issue is similar with WIN10 but not as bad as others are reporting. I did have one time where both mouse and keyboard stopped working. This includes the Logitech mouse and keyboard, AS WELL AS the keyboard and touchpad built into my HP laptop. 

However, since then the problem has been limited to Microsoft applications. When my keyboard stops working it only affects Word and Excel. I can still type into browsers. Actually right now I cannot type in my excel page, yet this is working fine. No idea why. I've also see that my mouse works fine on all applications including Word and Excel. 

I have found that closing the application and reopening it works about every other time. Again, no idea why at this point. But I figured just in case Microsoft has anyone reading these complaints. I'd let them know about this different behavior.

thank you for the update.   Anytime you have a good bottle of St. Emilion, I would be happy to fix your computer. <g>

I got my Msft mouse and keyboard today and just installed it.   I am in the process of again trying to update from Win 7 to Win 10.   I will report back on my success.   So far we don't know whether it is a usb issue or logitech issue or something totally unrelated to any of those.   In fact a number of the problems, but not all are on Asus MBs.   It does seem that the most consistent theme is Logitech however.

OK, I went back to see the technician.   (This was an opportunity anyway to give him a good bottle of St. Emilion for what he did for me at no charge.)   He remembered the computer and the problem.   He said that all he did was to deinstall some programs that he thought might be causing the problem.  The two that he mentioned were Norton and Avast.  I have been using Kaspersky as an antivirus.   I think Norton was on the machine when I bought it and I had tried to deinstall it several times but could not completely do this.   I don't ever remember using Avast which apparently is another antivirus program.  So, if I had the same problem again I think I would begin by deinstalling any program which is not regularly in use and which might be suspect.  Work through the programs one by one to see if a deinstallation has any effect.   Sorry I can't be more definitive.  Hope this helps.

I did ask him.    The only thing he said was something about the drivers for the mouse and touchpad.   I'm sorry I can't be more specific than that but this was all in French and my comprehension of the language is not 100%,  So far everything is working well.   I will try to see him at the shop again and point him to this discussion and try to get a more complete description of what he did, even in French.   This all took place at one of the Media Markt stores in Belgium.   Media Markt is the equivalent of Best Buy in Belgium.
