But that dint work either, the sys restore rolledback some updates but that was all the keys were still not working. Also 2 days after I found this problem, I did a system restore to a restore point that I had created about 5-7 days ago(in the restore point I created, everything including the keys was working fine thats y I decided to use the system restore).

I have tried removing the keys and cleaning under them with a soft-haired paintbrush coz I thought maybe there was dust under them that was obstructing the working of the keys but that dint change anything n keys were still not working after cleaning under them. I don't know if the keys have stopped working bcoz of downloading the anniversary update or something else. As far I know the rest of the keys are working fine coz I did an online keyboard test(or maybe some key I dont use aren't working n I missed it) They do not work at all and nothing happens when I press these keys. Specifically the letters:- W, E, R, Y and the TAB key and recently I noticed the Windows Key is also not working. But after the second week of October(i think, can't remember) certain keys on my keyboard have just stopped working for no reason at all. N its currently running windows 10 and I downloaded the anniversary update in september(don't remember). Ok so I have an Acer Aspire V5-471G laptop.
