Hi Mark,
Open Windows File Explorer
Create a new Folder on your C Drive called DriverBackup
Close File Explorer
Click your Start Button, type cmd, then right click Command Prompt and choose 'Run as Administrator'
Run this command and hit Enter
DISM /online /export-driver /destination:C:\DriverBackup
When that command completes, you will have a perfect backup copy of your Device drivers in that new folder, which you can store somewhere safe . . .
