since updates to win 10 my laptop no longer has functioning shift keys. i have checked sticky keys etc are all off. i have deleted driver for keyboard, restarted laptop to reinstall driver. i have been to laptop compies website and can find no driver updates for my model. acer 771555z.
any solutions.

When typing it is as if the keyboard were pressing only the tab, and other than that it sometimes only moved backwards. A few words back. That happens after having the computer turned on for a while, that is, it does not turn on that way. As time passes, it starts with that situation of going only words back when typing or leaving the current text box as if pressing tab.

I did some tweaks using Aulogics BoostSpeed 11. My keyboard is now working intermittently, but I'm not sure what tweak may have caused that. I will be typing and it will just stop recording my keystrokes for a few seconds, so I have to wait for a few seconds until the keyboard starts responding again. I have a new HP Envy laptop. Any suggestions? Thanks a lot.

p.s.: on the dropdown above for device, it gave me four options. I just selected what I think is the right one

Generally, copy and paste do not work with mouse druppin a meny. Now, I have to use tne keyboar,Control "c" to copy and control.'V' to paste. this has slowed my ompute use condiderably.
somtimes I can see a quick flas of the menu, but it disppears befoe any action can take place.
Any help to correct this would be appreciate. Thank You

My windows key on my keyboard does not work and I have tried to run different tasks in the task manager and several other things but nothing seems to work. I saw on your website that this program can help.
