Windows 10: Lag?

Basically, I have been lagging a lot, so I factory reset. Im still lagging a lot even though I have nothing downloaded... I need my laptop for school work

Random lag spikes

Hi,

We would like to know more about your lag issue:

• What browser are you using when you experience a lag?
• Does the lag occur in a particular game?

In the meantime, we suggest you run the System Maintenance troubleshooter. Here are the steps:

• Press Windows Key + X.
• Click on Control Panel.
• Select Troubleshooting.
• On the left pane, click on View All.
• Click on System Maintenance to run the troubleshooter.

Looking forward to your response.

 

One key has severe input lag but every other key is fine

The thing suggested by @lx07was yet another step of trouble shoot you need to perform to role out the hardware fail possibility than rather a topic for debate .
I honestly did not suggest it just because its level of technicality is a bit high and I am not quite sure about your level .
Yet however if you can do that step I can't see why not .
And yet even if you still manage to get lag you are down to the route I just discussed in my previous post , nothing more to do .

P.S I am not even sure what you mean that the button performs well if you change layout , the aussie & u.s layouts do not even acknowledge that button and most probably assigns a different function / key to which hints the conclusion of your test might be slightly biased

 

Upper right corner lag.

And the hotfix too, 10.12a over it as well?
sorry you may did but i no idea, so step by step.

And just make it clear;
your lag is the mouse arow in the corner/
if yes;
do you use samthing on sidebar?
if yes try to switch off and see...
just my one cent
