Windows 10: previous wimdow key

recently , i just replaced ssd in the place of hdd....but i lost my genuine window ... what can i do now?

:)

 

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

 

Taskbar bug: switching to another window -will not appear at the front


Follow either of these steps to fix the issue with the Active window hiding behind.

Method 1:
I suggest you to disable window by hovering over it with the mouse and check if it helps. To do so I suggest you to try the below given steps and check if it helps:

1. Press Windows key + X key and click on Control Panel.
2. Select or click Ease of Access.
3. Click or tap onEase of Access Centre.
4. Click on Make the Mouse Easier to Use was uncheck Activate Window by hovering over it with the mouse.
5. Check if issue is resolved.

Method 2:
I would suggest you to completely uninstall the touchpad driver and reinstall it. Kindly follow the below given steps.

1. Press “Windows key + X” and click on “Device Manager”.
2. In the list of devices, you should see the touchpad drivers.
3. Right click on the device and then select "Uninstall".
4. In the uninstall dialog, make sure you select the option to delete the driver package from the system. This causes the driver package installed earlier to be deleted.
5. In the Action menu of Device manager, select “Scan for Hardware changes” option. This will cause the device driver to be reinstalled. Once the driver is installed, close all windows and restart the computer.
