Internal Keyboard showing as Standard PS/2 Keyboard in Device Manager

Sr, I am using Windows 10 on my Lenovo Laptop. My PC was OK till I connected a PS/2 keyboard on it. After I disconnected that PS/2 keyboard, My internal Keyboard is badly working i.e it is autotyping a particular key randomly and whenever I go on Device
Manager, The keyboard Driver is showing as Standard PS/2 keyboard though there is not any PS/2 keyboard connected. I have uninstalled the keyboard driver and restarted my PC but there is a beeping sound and the Standard PS/2 keyboard driver is back on device
manager. I have also removed my internal Keyboard and reinstalled it but no difference was made. I have also attached the Standard PS/2 keyboard again but nothing worked. I also uninstalled and reinstalled Windows 10 but nothing actually worked. Should I buy
a new internal Keyboard? Will that fix the problem? I actually don't know why is my internal Keyboard is showing as Standard PS/2 keyboard in device manager. Please help and suggest me what to do to fix this.

My windows gone corrupted.As soon as I updated my windows , only the windows shortcuts of Standard PS/2 Keyboard (inbuilt) of laptop (Lenovo Ideapad S145-15API) are not working. I have done these following steps. Still no improvement was seen.

1. Uninstall Keyboard driver from device manager.

2. Troubleshooting keyboard

3. Command prompt.

And one more thing I want to tell you that when I use windows shortcut on-screen keyboard, it works fine or even using external keyboard. But the windows shortcuts (Windows + QWERTYUIOP) from the inbuilt keyboard do not work.
