Laptop on screen keyboard color changed

My Dell Laptop's on-screen keyboard color has changed from black to white after an update this week.
I don't like it!
Is it possible to get my old keyboard back, please.
This is not the best place to raise this issue as most of us are not computer geeks.
However if your laptop is running Windows 10, I believe you should be able to take the OS (operating system) back in time before the update occurred.

Should find this under ‘settings’
