    Windows 10: pressing the A, S and C keys at the same time

    i am curious how to get windows to accept pressing the a, s and c keys at the same time.
    whenever i press this particular combination, windows will ignore the c press and beep if i continue to hold down all three. all other 3 button combinations work as expected so its not a hardware issue, its just these keys.
    is this combination mapped to some special use in windows 10? if so, how to i disable that "feature" or remap the keys?

    "Turn on Sticky Keys", "Turn on Toggle Keys" and "Turn on Filter Keys" are all disabled.

    Seems to work for my system. Of course, as you can see, I never manage to press them in the same sequence at the same time. :)

    hm thats weird. i havent really changed anything on my windows installation.
    testing in this browser text box it seems a, s and c isnt the only combination. if i press k, p + i it will ignore the i press but if i press c, d + f then it WILL input f or if i press a, s + r it will input r but doesnt work for c.

    also for the combinations that ignore the third input, the order doesnt matter. if i press c, s + a it will ignore the a press.

    Don't you need a special gaming keyboard to be able to use multiple keys at the same time? Gaming keyboards use a special n-key rollover (nkro) property that allows them to do this.

    uh no.. "gaming" keyboards are just a marketing gimmick. any keyboard can support rollover if operates from hardware interrupts.

    my problem is a problem with windows 10, it cant be a hardware issue because some combinations work as expected.
    if it were a hardware issue, windows wouldnt detect the keypress at all and i wouldnt get the beeping sound when i try.
