Hi. My name is***** you for your question and the opportunity to assist.
Try rolling back the computer to the state it was in before the updates.
Right-click the start menu button and select Run.
The Run box will open.
In the text area type: rstrui and click OK.
System Restore will open. Click Next.
Put a checkmark in the box labeled "Show more restore points" (if visible)
You'll see a list of restore dates. Select a date when the keyboard and mouse were
working and click Next. Click Finish and start the restore.
This will undo the updates and if all goes well the keyboard and mouse will start working.
Let me know the result please.
